Thank you for explaining the "why" behind each of these code requirements. Its easier to remember these things when there is a practical reason for their existence in the code.
Awesome, thank you so much!
Got2Learn Good vids. And as you know the code changes every 3 years throughout the country. So inspectors and tradesman are constantly in learning mode to keep up with this 3 year cycle.
My thoughts exactly! This was a great video and it covered a lot of common plumbing issues. And, as Harry said, the explanations were really helpful!
Thank you so much guys!!!!
My point exactly. Anytime I show a new person something I make it my goal to explain “why” it needs to be done a certain way, and not just “how” it needs to be done. I’ve always found that it gives someone a better understanding of what they are doing, and a stronger appreciation of how critical a failure can be if not done right. ✨✨✨
As someone that does plumbing i can say it all comes down to the inspector and what you get him for lunch
You buy inspectors lunch? They have about 5 minutes to give me a sticker and get off my job before they end up in a trench somewhere lol
I used to worry about what to get an inspector for lunch.
Nowadays, I just get them a large-breasted, young blonde ...
and it is universally accepted.
@@marshalllhiepler Soooo what you're saying is, I just need to become an inspector to get a gf?😩
@@circasurvive9891 ,
You are understanding me correctly.
😂😂 true , a big plate lunch
Great job! Unlike 98% of all RUclips videos, it was short, informative, and to the point!
🙏🙏🙏
Again, as a master plumber I approve this message! It's funny plumbing is my life and on my free time I watch stuff like this! 👍
🤣🤘🤘🤘
😂😂😂😂
Get a life!!! Just kidding. You never know when you might learn something new, even if you are an expert at something. :-)
Shut up. You hate your life like the rest of us
Nothing wrong with that!
As a bathroom remodeling contractor for 40 years I'm aware of all of these. Most (even some journeyman plumbers) are not. My job as a general contractor is to know everyone 's work. Not just carpentry. Good video!
Awesome, thank you Don!!
I’d like to see more videos on code regulations. Especially videos like this “more reasons why you’d fail inspection” I think it’s a fascinating topic, and there’s a lot of things that can go overlooked by a homeowner/DIYer
Code is a very tough topic on the internet. Many cities, counties, provinces and states all have varying codes. Especially handicap accessibility codes and fire protection codes. Different construction methods also change code applications.
Agreed... I watch Plumber Tom a lot... He goes over the IPC, chapter by chapter... You get a lot of why it's done which is why I like his channel too.
This is by far the best tips and tricks channel though
I just moved into a house and am beginning DIY home repairs. I'm so glad I came across this channel because I have learned so much and just in time so I didn't make too many costly mistakes. Thank you.
Welcome!!!
FYI. As long as the 90 is a “SWEEP” it can be used. A short sweep is perfectly legal and usually what people get when they say “I need a long sweep”. The fitting that you called a short sweep 90 is actually called a1/4 bend and can only be used for vents or drainage from horizontal to vertical
I was told by an inspector that a medium sweep can be used if you are transitioning from a horizontal run, to a vertical run like a waterfall. I still use a long sweep anyway. Medium sweep NO GOOD for a horizontal turn for waste water.
U shouldn’t be using a short sweep u should be using a San T with a vent. The name applies to both you can call them bends or refer to them in degrees
Reading from the "Cabot" plastic piping handbook, the 3" fitting in question is referred to as a "straight 90 and has a take-up of 1 27/32" used in dry sections of the vent systems only. The 3" DWV fitting known as a 1/4 bend (90) has a radius of three inches and a take-up 3 1/16". Difference in radius and take-up is due to hubs on each end. There is no such DWV fitting as a medium sweep. For DWV piping there is only one radius for each pipe size, unless special order. Standard radiuses are, Short radius= 1 x Dia. of pipe, Long radius= 1 1/2 x dia. of pipe.
@@AyeCarumba221 any SWEEP can be used in verticals to horizontal or horizontal to horizontal applications. BENDS can only be used in drainage from horizontal to vertical or in vents
I am a plumber and you explained it perfect will share this video with all new employees great stuff. Best plumbing video I have seen on RUclips 👍
Awesome Alex, thank you so much for sharing!
Where can I find these codes?
Excellent video. I am a plumbing and gas inspector in Alberta and you're bang on, these are the top 10. A lot of my job is answering questions for people who pull homeowner permits (which I'm happy to do), but this video explains what they need to know so well that I'm going to start sharing your link. Well done.
I am very thankful of your comment Kevin, I really appreciate your kind words :)
We have none of this in the UK. No requirement to have pipework inspected. We also don't generally have vent pipes either. Only pipework requirements I'm aware of is that any tank overflow pipes cannot be connected direct to drainage - the overflow has to be visible - so you know it's overflowing - water saving requirement. The other requirement is where there are two sewerage systems - 'foul water' and 'fresh water'. You can't connect toilets to fresh water drains -as that bypasses the sewage treatment works. Many places have just one system and it all goes through sewage treatment works.
@@nuntius1933 The no back flow is a thing here, England and the no over-flows straight into a drain (although that might not be so significant now most of us are on water meters - so we pay for wastage). Other than that, anything goes. There are regs for gas and electricity, but home owners are not bound by those either - they stop non-registered people charging others for work - for gas work at least.
My dishwasher drain hose sprang a leak last night - so even quality of water parts used by manufacturers is not that regulated !
Hey Kev, Is there any way we could chat via email, or here?. I'm a new Journeyman, & i'm moving to Alberta in 6 weeks. I want to try & improve my code knowledge, & what better way than to pick the brain of an educated individual in the same field. Hope to hear back, ty
The city of Knoxville TN inspectors have always been tough on handicap dimensions and all the things you mentioned
They were also particular about commercial kitchens especially when it comes to proper venting of floor sinks and floor drains
Thank you thank you! Your videos are just so fantastic, the way they not only say what works and what doesn’t, but you also explain WHY!
#10 is fun to deal with on big homes with open floor plans. There is always a second-floor bath over the 1st-floor living room that is 40 x 40.
Man I really admire how informative and quality this video is. I've been studying plumbing codes when I can and was familiar with some of these. I learned some new as well,definitely a video that will save many people's butts . Keep it up man,you and roger wakefield are my favorite youtube channels when it comes to plumbing.
Thank you so much Ethan, I appreciate all of your comments and I am glad you learned something, mission accomplished for me, share if you can, it really helps!!
@@Got2Learn For sure boss! Also great job on the animation ,did a good doing it yourself.
Thanks a lot man!
I live in an old home built in the early 50's, my washer plumbing is indeed 1.5" pipe. I had issues with it sometimes overflowing too. But since I bought a new "HE" washing machine a few years ago that uses far less water, it's actually been working perfectly fine now. The drain hose on the new washer is only about 7/8" or so, and the 1.5" drain pipe is more than capable of handling the flow from that small discharge hose.
Awesomeeee!
As I am modifying some existing pipes, the previous plumber did a lot of the following examples that would fail inspection 😐. Good to know before I lay the patio. Especially adding a good and convenient clean out access.
worked for a plumbing shop in 1978.. one of the bins of fittings in the back of the shop where everybody walked was a really full bin of 3/4" galvanized street ells.. an elbow with female threads on one side but male on the other.. i stopped at that bin and screwed 4 street ells together just a few threads.. forcing the last connection to just be touching as i rotated the ells in place.. i hid to the side when the boss walked in.. he came to a skidding stop.. seeing the 4 elbows screwed into each other. he picked the assembly up and examined it closely. smiled and carried it away.. it ended up on his desk as a paperweight.
About the below grade drains, I saw another video about that. They said the same thing about using a 45 street ell in the sanitary tee to improve flow and reduce the chances of clogging. But it also has an added side benefit, in the event that it does plug, the longer sweep makes it much easier to snake out, as snakes do not like sharp turns.
Great job of describing ways to do, or to not do, something correctly. You've explained well things like,.... your description of why a "Y" is used and not a "T". This puts rationale behind the way drainage gets installed..... so that it will work. Good, valuable information for those who may not be properly trained journeyman plumbers, but want to do things right!
Thank you very much, have a great day Guy!
Other than replacing taps I would never do any plumbing myself but I love learning this so I understand what others have done. I had a new bathroom installed a few years ago with - necessarily - exposed outdoor pipes (I'm in Australia so no issues with freezing). I now know why all the things (e.g. the cleanout) have been installed as I am sure the rules are similar here to in Canada or the US
in my country (easten europe) you do it better by yourself because you don't really have a choice. the reason is that there are no good plumbers and they don't know any of those rules and regulations. the good ones emigrated to western countries and the ones that remained are extremely expensive and not available because they are working for important jobs only (not housing)
Great illustrations to screen shot for showing customers what's happening in their system behind the walls. Nice job. Thanks for putting this together.
Thank you so much Giovanni, I really appreciate your comment, don't forget to share :)
I don't know about others but I am keeping this as a reference to be checked any time I do any plumbing . Great video man !
Hehe, that's so cool! Thanks Robert, and share if you can :)))
Dude, this video was awesome and so informative. I just started plumbing this week and I felt so lost and this is the first video that gave me an understanding of how certain things work. Instant like and subscribe. Please continue to put out more vids
Thank you so much 🤗🤗🤗
Vents lower than flood rim of fixture:-- Although an odd duck for sure, the configuration for an island vent has a workaround for being an exception. i also love wet vents which usually get a knowing nod of approval from inspectors. I don't know your locale but in Los Angeles I stopped putting T&P on water heaters and instead just put a pressure relief outside by the shut off. No more pans or drain issues with old heaters inside closets. Always passed.
Not appreciated enough is the satisfaction of watching a main line stoppage let go, after you've been playing catch and release with a forest of roots, letting it tangle up just to the edge of the cable flipping in the cage, then yanking back, like fighting a marlin; then it goes BOOM like thunder and you may even have to hook the cable up to your truck and pull out a 10 ft tail of magnificent roots. You feel like mounting them as a trophy!
Retired plumbing contractor now, but thinking back, I enjoyed being Roto-Rooter man in L.A. Hollywood more. Every job was an emergency; calls in the middle of the night were like sweeping out of your bat cave, and whether you arrived at a swank Beverly Hills restaurant, a mansion on the hill, or some low rent apartment complex, you came in like a cowboy and everyone followed your commands, rich or poor. flooding sinks from floors above, main lines backing up into basements at exclusive country clubs. But all of them open sesame to you, fair haired hero of the moment!
My 1 century old building has many thing not "up to code" because there were not any code for many thing.
-No Shock absorber. (I did talk about my mom to not snap close foset because old rusted iron pipe could burst from their thin grinded wall)
-Many short 90° turns, also many pipe were done flat 0° so being so old the house ever so slightly sinked in the ground and now some pipe have negative ~-1 to -2°
-Many if not most 45° Y-Pipe on pillar sewer pipe are like at 3:13 So a mix of old pipes filled with junk plus that angle make most sink/bath and wat not "gurp"
Thank you for the awesome videos. I recently had to remove quite a bit of a 3 in waste stack to allow foundation guys to repair a structual wall. The tip about the horizontal sanitary tee saved me from a mistake since that is how they originally did it on my 3 in waste line where it merges with the 4 inch soil pipe. And yes I used to have to clear that blockage about once a year. Fortunately there was one clean out.
👌👌👌
Very well done video. Simple and to the point. Doing a complete tear out of my basement and relocating the bathroom and laundry room. As well as replacing all plumbing. Thanks!
Yeee hawww, thanks buddy!!
So well presented and explained. I love your use of diagrams. Also, I learned about that shock absorber thing from your other video :D Thanks for making these excellent videos!
🤗🤗🤗
Shock absorbers are not required on a class a pex system, but it is on copper, cpvc etc.
All great stuff, I'm no longer an inspector, but appreciate this as a refresher for work I do myself :) AT 03:50 you'd hear gurgling as the sink drained, an excellent indicator of a venting/drain problem :) great work, thumbs UP!
You are most welcome, please share if you can, it helps the channel tremendously ✌✌
@@Got2Learn How on earth did you have time to respond to a comment? Amazing!
@@FrederickDunn it's important to me and I always make it priority #1, thanks for noticing Fred!
I’m a plumber in massachusetts and we have to take a refresher class 8hours a year. Fairly new rule.
@@daveatkins3568 sounds like a good idea, it seems to me that the rules keep changing; just hope it's not another money grabber?
Thanks for putting up this good video with explanations. Those doing their own plumbing should bear in mind that these are "minimum" requirements, and that your local code may require some different or more 'robust' features, .e.g. washing machine drain no less than 1300mm (about 4 ft 6 inch) above floor level _not_ above the point where it ties in to the drain. Likewise, local weather conditions (i.e. winter) may specify where running water, waste lines and vent stacks must go, in order to avoid damage from cold air ingress or being close to a cold outside wall. (These also govern rules for things like sizing of natural gas hot water heater and gas furnace exhaust vents.
When roughing in, bear in mind that Code is a _miminum_ standard. In many cases, going one size up, while slightly more expensive in the short term, can prevent future problems that are much more expensive to repair once everything is closed in. As with electrical, it's much better to "do a bit more" at the rough-in stage than try to retrofit later on. If you are hiring sub-trades to do some or all of this work, do not assume they will do it to code, or to the plans, or correctly at all. There are many excellent tradespeople, but every profession has its share of "take the money and run" bums.
It's also worth remembering that some "big box" stores sell products - plastic accordion flex pipe sections, for instance - that do not pass code anywhere, usually for very good reasons. Just because they sell it doesn't mean it meets or exceeds local code requirements.
Well said Flying Beaver!!
I love your videos especially how you explain the problem but then go on to explain the implications. Most valuable as usual!
🤗🤗🤗
Great info. Problem is that the plumbing inspectors in Atlanta just made up rules to flunk the plumbing on my sister's addition in the 1980's. They disallowed the sanitary-tees in vertical pipes, claiming they had to be combo-tees, as you show for horizontal. They failed a screw-in PVC connection to older cast-iron sewage pipe, saying the PVC pipe had to be leaded into the cast-iron (wouldn't it melt?). They said the hot-water line to the kitchen sink had to be 3/4", even though it necks way down at the facet. The later was in the State code, but a great waste of energy and water waiting for hot water to get to the sink. They wanted the job redone by their "pro" buddies, even though state law allowed doing the plumbing in your own home. Much corruption in building trades.
At least by IPC code mostly right.
Short sweep 90’s are allowed for horizontal to vertical transition and for directly come out of wall to a fixture.
Double wye or wye fittings are not permitted to a fixture branch as shown unless it is vented. (Of course if the branch is vented his previous example of an incorrect why in 45 combination would also be permissible) A cross or double tee is permitted but most plumbers who have ran a drain machine will tell you 2 separate tee’s.
You absolutely can tie into another vent. His standpipe example is tricky because for washing machines you need to have soapsuds relief (it’s just a special venting style). Total vent size is 1/2 of the drain pipe served with a minimum of 1 1/2 inches so one and a half inches canserve a 3 inch main. Venting on most houses can be combined and come out roof in one single pipe.
I'm currently doing some DIY work on my place. We are about to start plumbing. You mention that vents can usually be connected to exit the house as one pipe. What would be the requirements for that? All my fixtures are within an 15x18 ft area (estimate) but I kept them close to each other to save on plumbing supplies.
trance_dance 30
Does vary in code but most use IPC. So you need a vent pipe to be 1/2 the drain pipe served with a 1-1/2 inch minimum. If the house main drain is 3” then it’s 1-1/2” If it’s a 4” main then it’s 2” vent needed. And when you exit thru the roof in frost areas you need to increase pipe size to 3” vent just before you exit so your vent doesn’t frost over.
All of your other individual vents can tie into this main vent.
Vents will slope allowing moisture to go down the drain. Also because vents are flowing air, tee fittings will upside down on a vent only line.
@@markchickenbutt8740 thank you so much for the reply. I'm finally to that part and the advice is MUCH appreciated
Hey@@markchickenbutt8740!
Hard to visualize this process, would be amazing to get some visuals on this.
Vents are sized not by the drain size although it could be a good rule of thumb but sized by the number of fixture units for the fixtures in the system. For instance a full bathroom is 5 fixture units so an 1 1/2" pipe is adequate but if you tie a kitchen sink to that vent it would add 2 fixture units to that and if there are any horizontal runs above that tie in you would have to increase your pipe size. once you get over 10 fixture units horizontal runs must be increased to 2 1/2" and so forth.
I’m an electrician by trade but also a finish carpenter and I can fix anything.
I do plumbing too
Any crackhead can glue pipe together and “ make it work “
But it’s knowledge spitting, like this guy, that turns us closer to craftsman and professionals.
I follow the general rule of only using a hard 90 on vents.
It was nice to learn that they can also be used on toilets too.
Learning about other trades helps us all out and makes us better craftsman.
Thanks for sharing your knowledge!
You do great service to others
Most welcome, please share if you can, cheers!!
ya I bet, fix the economy superman.
I'm going to school for plumbing. I found this video fascinating. thanks for the content.
Great video! Clear concise organized presentation while providing explanations of the logic behind each one.. Thank you.
🙏🙏🙏
I didn’t learn anything new from this video, but it was so well done!! The visuals and explanations were so helpful and informative!
Thank you so much, maybe someone you know can get something outta it, have a great evening :)
Nice
Best illustrative instruction I’ve seen on this topic. Thanks.
Thank you so much!
This was so well done. Graphics were awesome. You are concise and precise.
Thanks a million!!!
Drill plates are not always required for plumbing or electric; they’re only required when the distance from the face of the stud/joist to the surface of the pipe/wire is too little.
A simple sanitary T on the flat won’t work for long, especially with toilets as the flow can hit the T and split leaving solids to build up.
All of this is very helpful. But everyone also needs to keep in mind the code varies from one municipality to the next. So check with your local code enforcer if you have any questions.
Kevin Benecke 100% true
Yes, there are variations, but the foundation to pretty much all of the is the Uniform Plumbing Code or International Plumbing Code. In my experience much of the variance is in materials, like whether plastic pipe is allowed. I think much of what he mentioned is pretty universal. That said, talk to the local permitting agency for details. Or even call the inspector.
You’re wonderful!!!! We just finish the plumbing code module and I learned several rules even more than in school!!!! Your channels is way too professional 😂😂😂 way beyond for doitselfers
Thank you sooooo much, I really appreciate it, don't forget to share if you can :)))
Fantastic video, this has helped me to not make several mistakes, thank you
Thank you!! I'm doing the pipes myself, this helped allot!
A double sanitary tee makes near impossible to run a snake through it since it goes right through to the other sink and a clean out is not practical since there usually is not enough room. Where I live we use double "Y" or off set the drains. Sanitary Tee's also have a lot of resistance with flow even vertically installed.
Absolutely great info. I do my own work and always like to do everything up to code. Thank you 👍🏼
Glad it was helpful!
Just found your channel. Love it. Thanks for this resource for us struggling do-it-yourselfers.
🤗🤗🤗
I really thank you for the clear demonstration as an animation, it really helps rather than just explaining verbally. Well dobe 👍👌🙏
😇😇😇
Another reason for using a purpose built device for water hammer is that when that 18" section of pipe fills with water, it sits stagnant. Stagnant water can breed bacteria, like legionnaires disease.
Fantastic video!
Yes, forgot to mention that, thank you very much! Please share if you can :)))
Small comment, if you don't mind, but "harbor" bacteria is more accurate.
How true is that since all my houses and friends houses all have pipes that go past the faucet?
@ Not be a pacifist, alarmist or to high-jack this comment, but keeping the major concern in sight relieves unnecessary worry: First, the device's primary intent is to address water hammer and water-logging of vertical-pipe shock absorbers, of which a draining of the supply line can usually be done with minimal effort. Secondly, the contraction of the bacteria is generally by inhalation of contaminated water mist. Typical chlorination by the water company is enough to impede the bacteria's proliferation but not sterilize a potable water supply completely; pH, temperature, time and other conditions can affect its efficacy. Also, copper pipes have an ability to suppress growth. Biofilm can also form within the system.
I'm not a professional but do have experience and familiarity in the field and of the subject as well as a big concern of the vulnerability. I would be more concerned about hot water storage tank temperature before this (i.e. don't turn the temperature down to save on heating costs), and the conflicting issue becomes the allowable hot-water supply temperature (105F-120F, residential) versus this bacterial suppression (140F @32 mins., disinfection @158F-176F with circulation being beneficial); the answer - a mixing valve (thermostatic is the automatic of that). So at this point we have costs creeping higher and higher where history does not show a problem within this small specific area of focus (shock absorbers - the issue is more complex) although it is technically logical as the OP stated. Still, it is much more about inhalation of contaminated mist.
Good ones, but nail plates are not required unless the pipes are 1" 1/2 or less of the edge of the wall. Also You can't catch 2 different fixture from a drain stack unless both trap arms are at the same level using a back to back fitting(double fixture fitting). Regarding to tie-into an existing vent, its something you can do as long as you count all the fixtures units and ensure is capable to vent whatever fixture you will be adding. Clean-outs are required to have when is the end of the line, change of direction exceeding 135°, branches off the main larger than 5' , foot vents and long runs every 100'.
Thank you so much for these explanations!
Im a huilding engineer apprentice, and I always wondered how those water hammer cylinders worked... Thanks!
You are always so good at explaining everything. I learned a lot
Thanks so much Kev ;)
Honestly, I'm looking toward designing my own homestead in 1-3 years, so coming across this video on my recommended list was awesome! Immediate subscribe! While I'm intending to thoroughly read through the codes and make sure I am up to them in the design phase before even starting buying land and building, it is good to know the reasons why for things that would cause a failed inspection. I did a lot of work helping my godfather (who passed this winter from cancer) with remodeling an apartment building he was a caretaker of when I was younger, and I did plumbing, electrical, and basic carpentry work then, as well as taking an architecture class later. I know what I don't presently know now I can learn, especially with so much information online including the different codes, but it is wonderful to come across videos like that which actually explain the reasoning and show examples. Thank you!
You are most welcome, and sorry to hear your godfather has passed, plumb on my friend 🤘
@@Got2Learn thank you. My godfather had fought his cancer into remission three times before it finally took him. He and my father (who is still alive and he and my mother want to join me on the homestead since we're already in an apartment together) both taught me a lot about practical skills, and gave me the room to try things here and there. I was still in junior high when I fixed a toaster they let me take apart and use a voltmeter on, and replace a piece on a PS1 original with a piece from a thrift store cd player. My godparents and parents may at times have irritated me, as all parents occasionally irritate their children, but they were good teachers of useful skills.
Knowledge is everything.
2 years later you get to design your homestead yet?
@@VitaKet unfortunately, no. The plan was to purchase land and build a small home for my parents, and a separate one for me. However, because they're both disabled and making just high enough to have a spenddown in our state, very few other states are possible for moving to, without them losing medicare. Even moving outside our county would mean a massive jump up in co-pays due to programs here that help... and the price of land is too high within the county for anything that allows residential, let alone the fact that it has stricter building codes limitations than other places we were looking into before, which aren't feasible for them to move to at all. We're even in the cheapest apartment units in town, and yet the price of rent, utilities, food, co-pays, etc, mean that they wouldn't survive without me helping as able. Maybe if I ever make enough to get them set up somewhere that they're on half as much rent to me, or none at all, then I could do whatever separately wherever I wanted... but I'm not about to abandon them when no one else would help.
I live in a rural area & don't even need to have plumbing inspected, but this is good to know just so you know you did a good job & did it right...
Thank you ! One of the best explanation. Short and precise.
Excellent presentation. Great use of the visuals.
Thank you so much, yeah I made it so it was the most easy to understand as possible, thanks for noticing L, please share if you can ;)
Thank for the explanation of the horizontal drain. Didn't know that an angled pipe would suck out the P trap.
Most welcome!!
Always great information. Thanks for all your work !
thank you for good information!
Great information, I followed all this codes as a plumber
Niceeee!!
When I was a residential new construction plumber no inspector was the same. We had to remember what area we were in whether it was a city or county inspector. They were all different. Some things were the same. It resorts back to the code book. It says left to the discretion of the code inspector.
Interesting, in my 30 plus years as a codes consultant for over 150 jurisdictions, I never saw any legally adopted code allow inspector discretion. The codes are written in mandatory language; if an inspector claimed he had discretion he was flying blind.
Very nice instructional videos. I like watching your videos to help me improve my knowledge and skill level. Very impressed with the smooth and clear speaking of a complex technical dialog. A master is distinguished by making difficult tasks appear easy. Great Job 👍
😇🙏
Everything there you explained was correct my hats off to you that being said you could have a video that's 3 hours long explaining a whole lot more thank you for explaining what you did
Great job and as someone that does their own plumbing in remodeling jobs, I learned the code the hard way, well before youtube was invented and well before AOL...:) But, I only needed once to learn...Thanks so much for putting this up, it's nice to take time out of your life to help others, if everyone did that, the world problems would get sorted out much faster...Namaste!
You are most welcome :)
Main reason for #8 is, that this (old) version would create a "dead space" in piping, where bacteria like can Legionella accumulate
I've watched your video many times. Very helpful. I think this gives a home owner the ability to recognize poor craftsmanship.
What a great, practical and informative video! Thank you!
You SURE DO make thorough video's, with easy to understand explanations!
Glad you think so!!!!
Very comprehensive. And most importantly, accurate. Keep up the great work. Also there are many other ways to fail like S Traps. And too long of branch drains. I hope that inspires you to make more content as i will be shareing this video and more like it.
Thank you soooo much Carson, will do!!
Your channel has the right name, always learning something when watching your videos! Thanks for the explanations.
Glad you think so!!
In my area, the 2" washer standpipe has been required for as long as I remember (early 90s). Also, they don't allow normal pipe to be used as water hammer arresters. They have to be the bladder type. They were required for washing machine and dishwasher lines.
Get the $15 book on plumbing from the Home Depot and follow the suggestions - I passed every time.
In Maine, If you put a cleanout on a vertical drain through your slab, you must put an access panel in the wall
I just wanted to thank you 4 the video n all the explanation is hard to find someone that has a lot of knowledge and be kind sharing this with others thanks bro
😎😎😎
awesome info!
Thank you!
Metwood joist reinforcers are really handy when homeowners or builders dont want to build a box and want 3" pipe run through floor joists.
Never even knew these existed, thanks! (link to these: www.metwood.com/joist-reinforcers)
What's code today, can be a violation tomorrow. It's always changing. Not being to code, doesn't necessarily mean the job is bad, or that it won't work properly for many decades.
Totally agree with you.
Sometimes when someone follows existing codes and then after it is in service the powers that be realize they screwed up . A perfect example is a full size drip leg on a gas pipe and someone decides to add extra appliances with total disregard to the cubic ft demand of the added load
screw code
it always comes down to the inspector's EGO
Lll
I enjoy this videos. A lot of thought and prep goes into them. Well delivered.
🙏🙏🙏
All good info, well explained, with top-notch illustrations/animations. Thanks!
You are most welcome, please share if you can, it helps the channel tremendously ✌✌
Well worth the wait, good animation, and informative.
Thank you so much, don't forget to share Andre!
The cleanout also works as a test plug for inspection. Most inspectors like their drains filled with water to the top of a 10ft stack.
Absolutely, I should of mentioned this, thank you!
In the area where I live a test stack with 10 ft of water would freeze in the winter Here all the lines a capped and a air gage is used and filled with pressures air and it must hold pressure.
@@timhale501
That is true, but its difficult to test air on a plug. You woud have to cap off or does air work as well?
Very helpful info for us non-pro DYI-ers. Thanks.
we need more of these. plumbing inspects also teach the codes by default and would ingrain the thoughts
Thanks for the upload. I almost made a mistake that would have failed inspection (long 90 vs short 90). I appreciate the tips. If you could do a video about sewer pipe slopes that would be great.
Thanks Steve, really appreciate it buddy, I am glad you fidn't make that mistake ;) and yes, i'll be making a video on that too in the future! ;))
1/4" per foot grade on 3" and less
1/8" per foot grade on 4" and greater.
Use a level that has grade marking.
Simple.
@@98ek9 umm I thought 1/8" needs administrative approval?? old UPC........
@@jeffli2893 I'm in Canada. Codes may differ but regardless, 1/8" per foot on 4" + is enough to move solids.
Boosted DC2 we can do 1/8” on 3” and greater
The state plumbing inspector in Illinois will fail you for anything if he's having a bad day.
What a pain. I hate that his actual humor comes into play when it comes to passing or failing, that should not happen...grrrr.
It happens more often if you are in the city of chicago.
Same in California
This is true ever where and with every trade. Yes, there are inspectors out there that are the exceptions.
Find that in any state I've worked in. Even when you redo it the RIGHT way(AGAIN), BANG, NO-PASS! A Lot of inspectors don't read new codes. Or turn their back with their hand behind them looking for a bribe.
A lot of help. Good explanation
very informative video. Lots of great info for the home plumber, even a professional plumber. I have a question though. For #7 starting at 4:00 into the video, the illustration shows a santee as the drainage pipe which earlier you stated was illegal. Shouldn't it be a long sweep in that installation?
The plumbing illustrations are great - what CAD software did you use?
Great video. Good job explaining. Though, I'm unclear when adding a new fixture why it is not acceptable to tie into an existing vent???
Thanks, the reason for that is sizing.
im a journeyman plumber, nice work man, good info for people
an excellent and helpful video, thanks!
For #6, some codes require a clean out above a double sanitary tee, otherwise when snaking, the snake can jump to the other side of the tee and never be able to go down the stack toward the clog.
That was a double combo
I’ve plumbed for 8 years and have never seen a snake in a pipe on any job. I do run drain cables with drain machines to clean lines
It's a double fixture tee, a double combo creates an s-trap and is illegal.
Forgot to add the max length of waste arms for the sink. You are only allowed MAX for 1¼" pipe 5' of run and 8' on 2” pipe. Which by theory (if ran at ¼" per foot) prevents it from dropping more than it's inner diameter.
Thank you SO MUCH ! GREAT VIDEO!
Thank you for each explanation.
🙏
Some of this is brilliant but others are unheard of in the UK. Like drill plates, over here it is the dry liners fault if they put a screw though a pipe.
Also 2 inch trap and upstand for a washing machine is so over kill especially as it most always T's into a 2 inch float straight away.
I moved from the USA to Norway, where they also do not use protective nail plates. When my house was being built, I made and installed my own and the plumbers and inspector all commented on what a great idea that is. It also has saved me a couple of times both when I installed the sheetrock and afterwards when hanging shelves.
I much prefer preventing an accident over someone being liable for one.
Mr Sam Drywallers here are idiots 😂 Just kidding. Really though, they’re often in such a hurry in new builds that I could totally see someone not marking the sheet for the locations of piping, or not marking it properly, then screwing through a line 😬
As for the 2” standpipe for laundry, I wonder if it’s an appliance thing. Maybe the washers here put out more volume when draining? 🤷🏼♂️
Just imagine if the dry wallers drill a screw into a main copper supply and the screw only lets only a bit of leakage out , you won’t know till you see your drywall getting moldy, the nail plates are just an extra precaution.
@@orboflightning Just looking at how you boys do it over the pond, seems like you run a lot of pipes through timber! Must be loads of holes to cut! Can see how those drill plates come in handy.
We almost always have a void to run pipes, then the dry liners put up sheet steel stud work and then plaster board/ dry wall on top of that. Much less likely to put a screw through a pipe like that.
@@armandopena7921 true. But that's not a precaution that should fall on the plumbers. The drywallers should be doing that, if they are too incompetant to be sure of where they are putting their screws.
When calling my inspector for my rough in I take him to Wingstop beforehand. Works every time.
👌
I appreciate that you actually explained WHY these are violations.
