Thank GOD this isn’t another waste of time filler 12 minute video for the algorithm. Straight to the point . And more informative than anything else out there
Dude, you say more in four minutes than most of these guys can say in an hour. I really appreciate your attitude, your work ethic and your ability to explain things in an experienced way. It's obvious that you know your trade and you know how to explain it in a complete and concise way without going all the way back to Cain and Able in the Bible. Thank you for doing such a great job and doing such a great job on your videos.
Good video, i’m still not familiar with wet venting, but this one I got, and this would apply to horizontal assembly Do you have any videos of upper floors plumbing, with 4” stacks and two bathrooms back to back?? Thank you
He is in North Carolina and his pitch is not wrong. 3 in min 1/8 fall per foot. 2 in pipe or smaller 1/4 per foot. 4 in laterals you cal get away with 1/16 in per foot. Now that is said I still try to get the 1/4 per foot on all but the pitch’s I and he listed will pass code and inspection.
I can't thank you enough for putting these videos together. I'm building my own home and doing most of the work myself, including the plumbing, and the information you're sharing is priceless. Thank you!
Finally, I've been looking for this video for days, I had to watch half hour videos that in the end did not help me, thanks for sharing and for making it short but well explained and easy, bravo.
Instantly subscribed! If more contractors would use this short/sweet to the point videos- us rookies would cut our trips down to Home Depot from 10 to 4 !!! 😂
Jeff, would love to see a video on how the DWV is tested / inspected. Understand the concept, but would love to see the process step by step. Thanks again for the great content!!
Here in California, the minimum vent size is 2” for a w/c. I would rough a 2”x2”x 1 1/2” Santee for the lav and go straight up 2” on the dry vent by code in Cali. Thanks for the video, just subbed.
Great info. You might want to mention that while the slope and trap arm length may be legal in NC, it does not comply with Uniform Plumbing Code. Many states use the UPC and most use the International Plumbing Code. Please check with the plumbing inspector (Authority Having Jurisdiction) or you may be having to tear out your plumbing to make it pass code. All in all though, Great Job!
I stopped doing plumbing work in '86 . California. Watching your video surprised me with whats allowable now. Back then only vertical wet vent was allowable, and a WC needed a 2" vent. 2" trap length was 5' , 3" trap length was 6' . Horizontal vents from a wye branch needed to roll up above the center line of the drain too. Lol, my last code book I owned was the 1976 version.
Thanks for you videos...been trying to find out while watching videos and reading books...New construction with a basement full bath and laundry (roughed in, floor poured after passing inspection.) There is a pump in the basement floor to pump drains from the basement up and out to septic tank and I was going to tie main and 2nd flr drains into 4" where pump line goes through the outside wall. I have a full bath on the main floor right above, and a bath right above on the 2nd floor with 2 vanities, , oversize tub and sep shower. The kitchen is on main floor sharing wet wall with bath. My question is vents... Can I just use a 3"stacked vent all the way up for everything? Seems like a lot of fixtures...1 washer, 3 toilets, 4 lavs, 3 showers, 1 kit sink, 1 big tub. I just can't find anything to calculate vents per fixture even if everything is stacked on top of each other.
Great video. I know nothing about plumbing but attempting to DIY my moms tiny home. This is her exact bathroom set up. It’d be great to see how that ties in with the kitchen sink and dishwasher.
Cool short video, i like seeing the difference in plumbing in other states in the U.S. im from Massachusetts and its very close to what you explained. Only difference is the 3X2 wye and 2" wye would need to be rolled up above the drain, which is almost impossible to fit most plumbing especially if the floor is only 2x8 joists .
That was so awesome. Right to the point. I have a question. Do you have any experience with saniflow toilets or shores? We have an unfinished basement with access to main drain in crawl space and trying to find best solution.
I find it interesting all the different plumbing codes across this great Country. What's acceptable one place may be totally unacceptable elsewhere. For instance. Lets say that bathroom group was basically the only DWV in a small 1 bedroom cabin or such. Here where I live there has to be one full sized VTR. Don't forget: "It's not a mess up until the concrete is poured". Lol.
Yes, I wish all states, cities and counties were on the same page. You would think in 2024 that the rules are the rules but the folks who make decisions per to code can disagree just one county away here in MD.
I have a question. I have a 2nd floor. Where the water lines were run and capped off. Between them is a 3 or 4 inch pvc pipe that goes through the roof. The room next to this was framed for a toilet. How can I know if I can use this 3 inch pipe as a drain for a toilet and shower and sink? Thank you
Where I live, you can also come off of a 3x2 double wye with the trap coming off one side of the wye to serve a 1-1/2” trap and 2” wet vent serving the lav.
In California there are some differences, 2" diameter minimum for a vent that serves a closet regardless of drain size. (That sanitary tee would have to be 2" all around) 6 ft. maximum to the vent after closet. 1/8th in./ft. grade is only allowed for 4" and bigger Awesome video, just wanted to point out some differences
Hello - I hope this question makes sense. Would be easier with pictures. Currently my system of Vanity /sink1.5 inch vent, toilet 3inch vent and Shower 1.5 inch vent, all had their own vent going into attic and joining on the toilet 3 inch. With a remodel I am doing the bath will connect to the old vanity/sink line and have a 1.5 inch vent wihin 4 feet. toilet isnt moving. The main concern is the vanity/sink. it is moving 5 feet away from the old shower spot. Do I need another vent for this? Based on the video and already having 3 vents in the line... im guessing not, just checking. Thanks for the awesome videos.
Use the fall as precisely as possible, for example, 1/8" per foot for a 3" diameter pipe. If you pitch it too much, you can have all of the water run down the pipe and leave solids behind to harden into obstructions. The only exception is 45 degrees or more is treated as a vertical pipe.
If I want to add in a laundry to this fixture group, what are the options? Can it be part of the 2 " arm or maybe it can be, but that arm would need to be 3"?
Everyone seems to forget that wet venting is an exception meaning it's allowed but not preferable. The vent in the video is a flat wet vent meaning the vent center line is at same elevation to the drain it's connected to if you're going to use a wet vent the invert of the vent should be above ithe center to the drain line it's connected to
Hi there can you hook up 2 toilet and 2 showers and 2 sinks in 1 - 3 inches abs pipe With 2 vent it is all under ground in concrete it’s 1 story house no basement
what is the rule for the bathroom sink pipe i heard you have to have some horizontal run running to the wall before it drops so you are not making a s trap?
OMG! Please help! I am having such a problem understanding this. Are sinks the ONLY way to wet vent or can a shower, tub or toilet also be a wet vent? Picture this. I have a 60' main drain that will be under a slab and runs east to west through the house with the septic on the east end. I have a bathroom slightly NW of the main branch and septic. The bathroom consists of a shower to the NW, a tub to the North, a toilet to the NE a sink to the SW and a sink to the SE. The sinks are split by a doorway and are only 2' from the main drain. The toilet is about 13' from the main drain. Should I run 2-3" branches from under boths sinks North to South and connect the shower, tub to one and the toilet to one with the sinks being the wet vent? That would put the shower tub and toilet on the high side of the drain so will the wet vent work or does the wet vent need to be the highest point of the branch?
I have a question and maybe you could lay it out. We had a 5 foot roman tub, we had it removed and put in a large 3 head shower. We paid extra to have the concrete slab broken out and moved the drain the middle of the shower. We never had a drain issue with the bath tub, but when we put in the high dollar shower we have nothing but problems with drainage. Any ideas or suggestions, we simply do not use it anymore.
An Oregon the toilet vent must be at least 2 inch. And there must be a clean out at the end of every run. You can only use a closet bend or long sweep 90 for the toilet. All clean out must be at minimum floor level or accessible to the outside.
So on a wet vent I still got to run a vent pipe up threw the roof im adding another bathroom and just gunna tie into my main drain pipe wich is already vented from the toilet before it do I have to vent my second toilet or will the one vent from the toilet I have work with both
You would have to bring the 2-in vent up to the second floor and you would also need to bring a 3-in stack up top of the top plate on the first floor so that way you can run your drainage for the second floor. If you're able to wet vent the second floor, then you'll have the first floor vent coming up and the second floor vent coming up. You'll tie those in together or send them separately out the roof
I pretty much agree with everything you said, but we don't use sanitary tees like that for the lavatory. . Doesn't drain well with a sanitary tee straight into the drain line. We use short 90 then branch to the sanitary tee.

Great video! Can the sink and shower be on different 3x2 wye’s?
Nice channel. Quick question, what is the best material to use when RE plumbing the bathroom drains. Cast iron, PVC, or ABS?
Thanks!
Great video if the sink is not there, can you still use the same configuration? Meaning just the toilet and the shower?
Great video. I know nothing about plumbing but attempting to DIY my moms tiny home. This is her exact bathroom set up. It’d be great to see how that ties in with the kitchen sink and dishwasher.
I'll keep that in mind for the next video. Thanks
@@risingtideplumbing How much would you charge to provide a plumbing diagram with parts and pieces if I provided a floor plan?
This is t he most efficient bathroom drainage system I've ever seen.....excellent!
Thanks so much.
Thanks so much!

This is easier to understand than the teachers at plumbing school. I'm just in Chicago lil different
Wow, good stuff, My flumbing drain is fluged up 😅
Is the only one 90 or two 45s a rule just for wet venting or is it a general plumbing rule for trap arms?
One of the best videos i've seen. This guy knows code.
Ipc.maybe
Is the long sweep need on the sink drain line?

Like everything else in California, their vent requirements are as expensive as they are inefficient.

No plumber but remember the toilet as 1,2,3. 1 toilet 2in vent 3in drain. Also same answer for water head. 1 psi = 2.3 feet of head. Good video.
Use the fall as precisely as possible, for example, 1/8" per foot for a 3" diameter pipe. If you pitch it too much, you can have all of the water run down the pipe and leave solids behind to harden into obstructions. The only exception is 45 degrees or more is treated as a vertical pipe.
My old memory was that only until 4" were you allowed to run 1/8 per ft. Slope.
Nice horizontal wet vent 👍
All the specs in the shortest amount of time. What a chad.
Nice, Short and sweet. No B.S.
What if the toilet was wall mounted? I am having trouble figuring out code for that and how to set it up for the foundation pour
Is it possible to put a washing machine standpipe into a 4 inch wet drain that drains from the 2 nd floor?
Can I use this wet vent system in Sacramento California?
Damn good video. Make more
I've heard that the toilet needs to be downstream from the other fixtures when wet venting. Is that what you have here?
If I want to add in a laundry to this fixture group, what are the options? Can it be part of the 2 " arm or maybe it can be, but that arm would need to be 3"?

Dry vent isn’t preferred anymore, if there’s a clog it won’t have water going through it to flush any solid out
Hi there can you hook up 2 toilet and 2 showers and 2 sinks in 1 - 3 inches abs pipe With 2 vent it is all under ground in concrete it’s 1 story house no basement
what is the rule for the bathroom sink pipe i heard you have to have some horizontal run running to the wall before it drops so you are not making a s trap?
Gerber WC makes a 10” rough in from the wall in case your tight on space
Very true. Thanks
Yeah, plus most plumbing supply houses can get almost any brand for 10", 12", and 14" rough-ins. Good video!
Shouldn't the WC be connected after the lav and shower drain?
Under. Fucking. Rated. This guy needs waaaay more subscribers!

What are the problems you've experienced, and how long did it take them to occur?
Excellent, and only 4 minutes instead of stretching it to 10...
Will this way work also if im doing a double vanity(w/cross T and 2" going up for vent) ??? tia
Yes
An Oregon the toilet vent must be at least 2 inch. And there must be a clean out at the end of every run. You can only use a closet bend or long sweep 90 for the toilet. All clean out must be at minimum floor level or accessible to the outside.
How far can the main drain be from the toilet?
Using the wet vent shouldn't that be 2 in up from lav ?
Sorprenderme y as este mismo diseño de otra forma, cumpliendo el codigo
So on a wet vent I still got to run a vent pipe up threw the roof im adding another bathroom and just gunna tie into my main drain pipe wich is already vented from the toilet before it do I have to vent my second toilet or will the one vent from the toilet I have work with both

If you're able to wet vent the second floor, then you'll have the first floor vent coming up and the second floor vent coming up. You'll tie those in together or send them separately out the roof
Also, if you do tying both vents together, it has to be above the flood ram of all fixture units on the second floor
