We have a leak pro here, cause of you I’d love to work for them. You’ve taught me a lot in the last 3 years of me being a plumber. My first comment on your vids was about how hard it is to find a job to become a plumber. I went from 15hr to 19 hr to now 21 an hr. I’m just three years. Thank you for you inspirations and your info. Keep the dream alive.
That is awesome! Keep on learnin brother 💪
Running the water to fill the traps in rarely used areas of the house - GREAT ADVICE!! Thank you Roger!
I had a clogged vent pipe for years and didn't know it. It wasn't until I started noticing that the sinks, shower/tub and toilet were not only draining slower, but water was coming up through some of the pipes followed by, well, you guessed it - the smell. I ran water down mine and had someone keeping an eye inside just incase the piping had a possibility of leaking. Basically, a lot of pine needles were the issue (again, don't know how many years, but it had obviously gone neglected. Everything instantly started draining far more efficient than it ever had. I'm the tenant of the home, and unfortunately, the property management can't always put in a speedy work-order in, so if I can't manage a few maintenance issues myself, I'll go ahead and do it. Probably one of many reasons my property manager keeps me around, lol. I'll be getting back onto the roof today because the issue is coming back, but, thankfully for me, the part of the roof the vent pipe is located, is on an 8ft flat roof rather than a much taller and steeper one. I'll be placing a cap over the vent this time to allow the plumbing to do what it needs to do and prevent outside interference from coming back in.
I work for a commercial service company and quite a few of our calls are vent related in that we usually have to extend them above parapet walls of business because the sewer gasses were escaping back into A/C units of the businesses. Vents are integral and definitely unsung heroes of the install!
Thanks for the info. I needed that tonight👍
No problem 👍
Well this gives me a decently good idea on how to go about making the new drainage system for my grandparents house, as that thing is nearly 70 years old and it's been long overdue for a overhaul since i was was a toddler
I’m just learning about DWV piping and this video helped a lot. Better than reading a few chapters in my textbook 😆
Amazing! I'm a homeowner and a sharp plumber asked "Do you guys use the shower down here in the basement?" Me: "No we never use the shower". Plumber"well that is the issue everything is dried up". He ran the water and just like that my sulfer smells were gone! So happy it was not a serious issue.
Gotta keep those traps hydrated! Glad y'all were able to fix the problem!
I'm suffering from sewer gas in my apartment for over 3 years now. I only smell it whenever it rains fairly heavy, and 98 percent of the time, it's in the evening or at night. It's making me sick, so I'm trying to figure out what I can point maintenance to. I do have a second bathroom with a cube shower that I never use because no matter what I do, the shower curtain sucks into the shower and constantly touches me. I've never once considered the shower being the problem causing the sewer gas, because the smell ONLY comes from my washing machine. I have never once smelled it anywhere else.
I have been using it for storage for things like huge packages of toilet paper, that absolutely won't fit in the single cabinet or under the sink.
Tomorrow I'll pull everything out of that shower and, and make sure I run it for a minute about every 2 weeks... I have no idea how often I should do it, actually. Maybe I'll just run it for a minute every day until I figure out if it solves the nightmare or not. If the smell comes back anyway, I'll ask maintenance to climb up on the roof.
Roger, I know it's a sink demonstration... but push fittings...
Just bust out the Flux!
I enjoy your channel man. Thank you for taking the time to post and make videos.

I’m a handyman own a couple rental houses was in basement saw leak coming out of cast iron toilet piping. Ending up opening wall up to discover 3” cast venting was all corroded and crumbled onto itself. Needed to replace with 60-ft pvc from basement to roof. Toilet finally flushed like it should.
Had some issues with frogs going down into the plumbing vent stack on the roof a few years ago. Don't think the frog liked the shop vac sucking him out of the line but decided to put metal hardware cloth on the top of the pipes with a pipe clamp to hold it into place. Works well and keeps critters from trying to get down in the pipe.
That's a fantastic idea! I'll mention it to maintenance when they come... Thank you! ☺️
Hi Roger, could you please make a video about deciding between Residentia/Commercial apprentice vs. Apprentice security and fire protection plumber.
I recently replaced my toilet with with a new low flow Kohler. The master bathroom toilet and hall toilet are back to back with a shared vent. When I flush one toilet I notice the water level lowers on the other toilet. Could the vent be clogged causing suction?
This is timely, I'm actually having an issue with that exact thing and I was wondering if it was the vent stack, again. About this time last year we had a plumber come out and pull stuff out of the vent stack, and it opened all the drains up. We live in a forested area with a lot of little critters, and well, you know. I can probably save the plumbers a trip, if I can unblock the vent myself.
Hopefully you’re not scared of heights!
Thanks for this informational video. I have question. I have one drain that I want to use for a kitchen sink and a clothes washer. I know it isn't recommended to have both on same drain, but how can I make this work. I have 2 inch pipe that runs approximately 2 or 3 feet then branches off to a 3 inch abs pipe.
Great video, I think you may need to talk about vent blockage prevention... Are there things you can do to the vent pipe to keep animals or other things from blocking the pipe?
There are! You could use wire mesh to cover the top to allow gases to still escape while keeping animals from getting side, or like the thumbnail shows
we have House traps in NY- our neighbors sewer or the whole neighborhoods sewer stink doesn't affect us if a trap dried out
Happy to find a second vent pipe and plumbing video on your channel today!! You are definitely helping me understand my household plumbing.
My next quest is to understand the cast iron vent pipe on the outside of my 1929 two story house. I'm not sure it even functions, how could I test it? Ty
You could put smoke down a pipe and see if anything comes out…I’ve made a video on that too,
This information is so valuable. I called a roofer for an inspection and they told me the plumbing vents had cracks around them and that caused wet spots my ceiling. Should I have called a plumber instead? I really thank you for making this video.
What style vent cap should on on top of the outside pipe for a toilet? I see some with just an open pipe and others with a reducing cap.
Got a question. We moved into our new manufactured home in march of this year. The last few months or so I’ve been noticing sewage smells behind the house and on the side. We’re on a septic system and it’s all new as well. I’m curious if the smell could be coming from our plumbing vents? The septic is a good ways down the way in the front yard along with the tank and there’s no smells or wet spots so it’s not that. Any help would be appreciated
I just acquired a shop with a small 1/2 bath in the back. No vent. The sink drains slowly and the trap often gets sucked dry. Will be adding venting in the next few months.
I would like more info on toilet venting . We have remodeled bathroom (2 full baths in s split level home). When the upstairs toilet flushes, it bubbles in the downstairs toilet! I could use some help with more information. Thanks!
Thanks, Ann C
A video on waterproofing roof penetrations would be a great follow up on this video.
That would be 👀
#1 in the #2 business!
Do you recommend a vent cover to keep critters and debris out or leave it exposed is generally?
I noticed my home didn't have a vent stack on the roof, only to find a T with to pipe that was covered by insulation in the attic, house was built this way in 2007! I added a 2" extension for now, but I assume it clearly needs to go out of the roof?
Hey Roger. I'm terrified of heights and roofs. I get scared to look at my feet some days haha. Is that something that could be a deal breaker when it comes to being a plumber?
My house was built in 1955 and has a few fixtures that aren’t vented, however we’ve never had issues with sewer gases. The toilets are vented at least so they flush well.
My stack has a small crack at the bottom. My good friend is a union plumber, so he mostly does commercial. but he bought me home (from the supply house and i paid for it) a huge fernco and we banded it, its been on there for like 13 years
Just what i always wanted to know. 😂
Do this work the same for the kitchen my sink not draining an been trying everything
What's the minimum height for the plumbing vent on the roof? Is it OK to shorten if next to a solar panel?
My toilet on the top floor of my brownstone is not flushing well & when I pour a 5 gal. bucket of water down the toilet it doesn't go down right away. Could it be the vent on the roof? I've tried to snake it with an auger & also took it up to see if anything was stuck in it, but everything was clear. I do have an old model Kohler toilet, could that be a problem as well?
I have a house that was my grandparents place and was built back in the 60's. Far back as I can remember the toilet would always barely flush and wiggling the handle was the only way to get it to flush. My grandfather had a plumber convince him to split off the septic system so gray goes to the tank in the back of the house and brown/black water the tank in the front. After having it done it still didn't fix the issue. After I took over ownership I was determined to get it fixed. After having multiple plumbing experts out finally one of them figured it out. Since the tank in the front yard was part of the old system from the 60's and was connected to the toilet. The vent pipe was also from the 60's in the wall which they liked to use metal pipes. Over the years rust had accumulated at the bottom of the vent pipe blocking most of the air. The plumber was able to snake it out and flushed it out with water. So to prevent it from happening again I was instructed to flush it with a garden hose ever so often.
they loved to use cast iron offset bends back then, to offset from an exterior wall in past the foundation or header beams. they were often too sharp radius, large rather flat horizontal between them, used on both the waste and vents.
Sadly it made perfect shelves for debris falling down the vent/stack to clog, I've found things like rodents, birds, cats(usually dead) balls, toys, rocks, boulders, roofing materials, cans bottles and more stuck in them, often times they'd use them at the top of wall to get further back from the roof edge. 🤬
I live at the top of a hill. Some days the sewer gas smell coming out of my vents completely stinks up my yard. Then in the evening when I turn on my house fan…. The whole house smells like the vent pipe.
For a long time I thought it was a drain trap… but no. It’s coming in. Even in the “winter” (California) the furnace running pulls the sewer gas through the poorly sealed skylight. Or down the gas oven vent or down the chimney. It’s not all the time. Just calm still days, and maybe when something is wrong with the city sewers.
Drives me nuts. Want to put a house sewer trap on but I hear those are a clog nightmare.
Hello, I have a question my basement washroom is letting out sewage smell. I took out the toilet and capped the flange but now the smell is coming from the shower. I poured hot water down but it seems not like it’s not doing the job. The p trap for shower is full of water but it’s still smell.. help please what can I do?
It’s funny your last name is a big city in the UK! Love ur videos man
Could an obstructed toilet vent cause inconsistent flushing, slow flushing, big gurgling bubbles sometimes and sometimes not? My toilet vent goes up in to the attic, takes a 90° turn to a horizontal run, then turns 90° and goes up out the roof. Can I drill an inspection hole in the horizontal and run a camera both ways to look for an obstruction?
Yes a plugged or clogged up vent could be causing the slow flushing, if you’re positive the clog isn’t further down the drain line
In South Florida it's ,+ Tree frogs that plug up my vents they hibernate over winter then cross rainbow bridge , over years there's skeletal havoc occurs
My house has a sewage smell that comes and goes. I've had so many plumbers come out to assess the problem, and I tried a few different options, but the smell is still there. I believe it's the vent pipe. Either there's a hairline hole in the pipe or a smoke test that may need to be performed. My problem is not trusting who's providing an accurate diagnosis. I don't have water leaking, but every time I wash or after the dishwasher is done, the odor is reaking. Then there's times when nothing is running and the smell is just overwhelming. I have to open the windows, especially in my bathroom. I run the water in the basement bathroom sink and flush the toilet about 2-3 times a week, and when I do wash, I pour a gallon of water in all the drains in the basement I sometimes add bleach, baking soda and vinegar to try and eliminate the odor. I live in the state of Illinois. Do you have any recommendations/ referrals for a great plumber in my homestate? Thank you so much .
How do we vent the plumbing in a very old house. It was either installed incorrectly or prior to codes. We are having a terrible time finding a plumber to hire so it might be something we take on. Every time I do laundry suds comes up in the tub and the toilet starts to burp and solids start back washing into it. There is always brown clumps of crap in the toilet.
What is the purpose of studor vents. A family member lived in a second home for a few years and took out a studor vent, which I didn't discover right away. How important is it to find out where the vent was from and replace it. I think it may have caused water hammer. Could it do that?
A studor vent was designed to replace an actual drain vent. And water hammering is caused by pressurized water line not drainage pipe.
Help...Sink in the bathroom backs up when the washing machine empties. The toiled flushes OK.
My kitchen sink doesn't drain and had plumbers out to snake it out and still gets clogged could that be my roof vent? I haven't ran water down
Hard to tell, I'm not sure how the house is plumbed...it could be an issue
Where's your sink located in your house?
I have a small leak in my toilet plumbing vent pipe, in an old fitting joint in my attic. How is this possible? Also . . .
I’ve noticed the toilet started flushing a little bit less effectively, but nothing major.
Shouldn't the little exhaust pipes have rain caps? I mean a rain gauge takes in so much water? I swear mine are putting water into my ceiling. There's water spots on my ceiling in those areas
I hear my pipes making a light rumbling sound when I flush. I have an issue with sewer Nats. I have no smell, but when I drain or flush my furthest commode from the sewer tank?
Nothing comes out at the clean out! Nothing backs up through the commode or bathtub either! However, if I leave that flapper valve open in that tank. It'll take a few minutes but it'll push everything out! Can I run a water hose into my vent from the roof? This is the only thing I haven't thought of until now. I don't have a snake. Again, no smell & no back up but it's not flushing all the way down that slanted sewer pipe.
Hey I'm a number 1 better than being a number to nothing like some toilet humor
No snow in Alberta Canada 2023/24 I thought I had a 95% frozen problem from my shop to a open lagoon... I could fill the system with hot water twice a day and it would drain slow... Day 1 I had burping in my floor pit I thought trap was dry because I had not washed a car in months so I filled pit with water and it took 2 days to drain... Filling all the pipes with water twice a day created a vacuum on all the traps and vent pipe... I didn't think of the Vent pipe till 2 weeks in and the next day All the sewer system was clear and working... I think it was the vent from day 1 because of the Burping :)
I have one bathroom used very regularly. One roof vent. In higher wind I get the sewer gas smell. Particularly in the tub where the p trap is not as deep. The vent is wide open to atmosphere. What is the fix? A ton of videos on here telling me the problem I already know. None tell us the fix. How the hell do I stop it from syphoning the p trap? It's there a cap available to negate this? Is it safe to use in freezing conditions? Thanks. Ps not yelling at you just frustrated I can't find an answer.
I have a trairer. Ever since we had the septic tank the outside has a awful smell
Well my best analogy is are behind water and it flows downhill LOL 😅😅
The opening of the sewage pipe is directly below the vent in the yard.Mine is any way,maybe everyone's is.
Im on septic have horrible smell checked everything had several companies out never have been able to fix it and they can't find the issue ... 🤢
hay rodger i ve noticed on your 4-in your Y is backwards
Keren👍🏻😍
Is there a tour video on that Browning safe?
Check out my Saturday livestreams, I leave it open 👀
I thought I had a plugged vent, I had one bathroom sink that stunk all the time. Cleaned the P trap of any crud, cleaned the pop up drain, did the baking soda/vinegar trick, etc. Turned out it was the over flow from previous owners being full of crap and slime. Cleaned that, and smell went away,. and saved me from climbing on the roof to check my vents.
when cleaning your sink/s, part of the routine should be running full hot water with cleaner in the sink, until it runs down the overflow fairly quick, then release the sink letting it drain as fast as possible. even start/stop it just as it gets draining fast, that will cause the water from bowl to surge backwards and down the overflow fast helping loosen crud.
wow you help me a lot about something i never knew or stop think why stinks i try your thing water in sinks i don't use lots not more stinks ??
My son is 14 and I'd like him yo learn your trade. As his dad i know nothing about plumbing. THANK YOU!!!
In my non biased opinion..plumbing is the best trade! 😅
@@RogerWakefield where should I start? Online classes? Just something to get him in the door. Thanks 👍
The United Association (UA) apprenticeship is a great way to start a career in this field and more. You can learn several trades
was that your pops at 2:48? He sure looks like an older Roger!
He ain’t as good looking as me 🤣
@@RogerWakefield You got a point!
I used a blow bag . It cleared up
Well I’m curious, is it normal for a house to have only one vent on the roof?
It varies, but every house will have at least one
It also depends on the location of the plumbing. If you have a long or big house with plumbing fixtures at both ends you increase your chances of multiple roof vents. I like having fewer penetrations in my roof-fewer spots to have a water leak. The boot had disintegrated around the vent and was actually the source for water in the basement. My old 1930 home had one inch and a half galvanized vent. Roger would get a chuckle out of how hilariously messed up everything is. Going to have it all redone. The only thing vented right is the washer and dryer that was relocated. Supply lines were all replaced, the DWV system is next but making that coincide with the bathroom remodel.
@@opinionatedman My house only has one vent, the master and second bathroom are close to each other. That would explain why there’s only one vent.
My previous landlord who originally just built a house, had added to his building later on converting it into a triplex.
About every 4-6 months he would grab the garden hose and put it down the vent pipe and would turn water on through the hose to flush the system out. My speculation due to watching this channel, is that the triplex was built with S-Pipes . Though this is San Joaquin County of California and homes were built with…creative liberties and friendships with inspectors between the 1950s and up to the 2010s. Plumbers are very busy nowadays fixing said old creative liberties
I want to harvest sewer gas as a substitute for cooking gas. It is made from hydrogen sulfide and methane. I know how to scrub hydrogen sulfide from methane. The question is how do i harvest sewer gasses without compromising the function of the vents.
this question is out of my range...I like your thinking
I have a blocked vent on my roof. I have slow flushing toilets. When the master bathroom bath is unused (the trap dries out), the toilets flush better. I can hear the sucking of air over in the tub.
I cannot get a plumber to go on the roof to clear the vent. No plumber in my county, or neighboring counties will take any “roof” work. Insurance seems to be the off-ramp. (In Central New Jersey) I am trying to get a Chimney Sweep to take on the job, literally.
I’m too old, my balance stinks. I’ll take comments and suggestions.
I need to extend my pipes. If you can access the attic. I’m thinks of cutting it then adding a couple to connect back to check it out!
Why did water came out of my vent ?.. my front porch had water
I have never heard of plumbing vents. Do these affect neighbors with shared well water?
Hi
Howdy
Thanks for the big secrets now the whole world will be a better place ok plumbers now you can do a better job the secret is out !😵
Plumbing Vents prevent homes from being Bombs
There are no vents or pipes going through my roof. I found them capped off in the attic. But there's no smell, and everything works fine. What dark magic did the previous owners employ?
Uhhh what? What about in your crawlspace?
How many bathrooms in your house?
Are those sharkbites I see??
QuickFittings…
I am so happy I was introduced to quick fitting s for temp work
😢
what's up?
the biggest secret is not standing down wind or sniffing them.. 🤪
seems to made them stinks go away thank's
