Thanks fellas. You confirmed my thoughts
You betcha!
What part were you struggling with?
Tub trap arm length to wet vent. I have trap arm distance of 7.5 ft.
If I make trap arm 2" pipe from tub, do I need wet vent bigger?
I am old school, vent all but have bathroom now, that is making that difficult. Trying to learn wet venting.
Thank you
You're welcome
Can you explain upstream and downstream in regard to wet venting, and where you can and cannot put a WC(toilet) in relation to the other fixtures? Thanks
Great information here thank you guys. So this brings up a question, I have a Bathroom on the first floor of a two family home. There is a 3" existing soil stack that Ill be feeding the fist floor soil drain to ( 3" obviously) this first floor Bathroom is a Lavatory, Toilet and Shower in that order.. I have to drain the toilet to the middle of the 3" horizontal soil pipe before the shower. So I have 1 1'2" sink, 3" toilet and last 2" shower. According to your instructions, a 1 1/2" vent rise from the sink at through the roof would not be adequate to vent this arrangement? Assuming I'd need to vent each fixture?
Many thanks in advance. Oh by the way, Im under the IPC
I had so many questions, I now have none. Thanks!
Happy to help! If there’s any questions you have in the future. You can contact us in our Facebook group. The plumbing gurus
There's no maximum distance on the length of wet vent, as long as its all part of the same bathroom group.
Exactly!! Thanks for the feedback and for watching.
Thanks for this great video! It’s very well explained. One question : can you connect the 1.5" vent to your main vertical soil vent pipe ?
It has to connect to the vent above all fixtures in the house. So above the upstairs flood level rim. It would need to tie into another vent near by if there is one. If there is not you have to locate one and tie into it.
Unfortunately when they built the house they installed rough plumbing in the basement but no vent pipes. What are my options if I don’t want to tear down many walls in the house ? Is an AAV legal? Or can I install a side vent through the foundation wall ?
Thank you for your video. It looks like the 2-inch line from the sink and the bathtub tie into the system after the toilet. I thought the toilet must be the last fixture tied in.
The toilet is the last fixture tied in upstream of the wet vent.
Great INFO, I have a master bath remodel in a Mobile home where I'm installing a Neo shower on an outside wall where the garden tub was located. It had a mechanical vent inside the tub cubby. So I'm not sure where or how to vent it???
Thanks for the comment.

Hey guys. Great video... quick question. I see how you have dropped a 2" Y from the 3" line to the toilet.... my toilet is in the middle and sink is on one side and shower is on the other side. Can i add 2 Ys to the toilet line? Also if i am able to do that, i would need to take 2 vents, 1 each from the shower and sink and have them join somewhere along the wall and then vent the combo together into 1 pipe going outside. Thanks in advance for your reply
Your best bet is to follow that drawing. But if you want to also contact us in our Facebook group “ The Plumbing Gurus” and send some pictures.
Good to hear from Calagary Ab. We recently bought a house near Okotoks with an unfinished basement. It has a section about 6ft by 10 ft with a 4in pipe projecting from floor by 6in and capped, obviously for toilet. It also has a 1 1/2 in pipe from above running vertically down the wall about 2ft to the left of the 4in pipe with a 90 stub capped and a cleanout. Also a 2in pipe from washer on above floor running down about 3ft to the right of the 4in pipe in the floor. I WOULD LIKE TO DO THE WORK MY SELF BUT A LITTLE CONFUSED as to where to connect etc. I hope u can figure out what I'm trying to say. Regards. Andy S

Thank you
Can you add a clean out to a vertical stack vent that is in the wall, so its east to clean out both directions? What kind of fitting would I use?
+FixmyToyota
Yes you can. You can use a line clean out or a Y with a fitting clean out
That last bit about the toilet being the last fixture, you pointed at the 2” and said you can’t tie in there. Assuming the pipe was sized to 3”, would it still not be the last fixture? I’m a little confused. I do appreciate the time you took to make this video. Maybe another video demonstrating improper wet venting would clear that up. Again, thanks for the video as horizontal wet venting definitely perplexed me
The IPC has a chart listing stack size, vent size, total DFU and and maximum vent length. This chart corresponds to a 1" WC maximum pressure differential across the traps within the vent line. It is important to follow these guidelines to ensure that a flushing toilet will not cause your sink trap to evacuate, for instance, which would allow sewer gases into your house.
thanks for watching and leaving a comment!
So where is this y thing located? Do I have to tear up floor and walls? I'm comfused. This is no James jam his wife Cindy
What other rules are applicable to ipc wet venting. Toilet is last fixture. Run has to be under the pipe id in length. Help me understand this. Thank you

There we can help you further.
I have a question. Could you tell me if my layout is correct or not?!? So I’m installing a bathroom in my basement, which includes shower, toilet, sink, and then also a washer machine. From what I understand of the plumbing code, I’m planning on wet venting everything back to the soil stack (which vents thru the roof). The toilet would be a 3” - 10’ run to the soil stack and then it would pick up the shower (2”) about 5 feet down the run, and then it would pick up a non dry vented sink about 8 feet down the run (2 feet from the soil stack). Is that a proper layout? And where am I allowed to tie in my washer machine drain line (which will be vented individually through a AAV)?? Thank you very much in advance!!
Hi. Join our Facebook group. The plumbing gurus.
We can help you out further. You can even post pictures and such.
How high above the vertical 90deg can you put the clean out? Is there a min on how close the clean out must be?
+John Perricone
Great question. Usually you want the clean out right above the floor. There is no min max but it’s easier to use the clean out for draining cleaning when it’s installed closer to the floor.
Congratulations and thanks for having the most easy to understand wet vent residential video on UA-cam!
Just one question - what is the requirement for the wet vent wye connection relative to the waste line? Is it correct that (unlike a dry vent) it has to be in the horizontal plane (0-45 degrees) to maintain the air layer at the top?
Thanks! That means a lot. If your main toilet line is running horizontally then it is best to keep the wye on the horizontal yes, you can roll it up a bit if needed. But you can also wet vent pipe on the vertical too. So I don’t think there’s anything g in the code saying that you can’t roll your wye on top of the pipe if you had to. You just need to make sure you keep proper grade. Hope this help. Thanks for watching
Awesome video. Would it possible to add a double t fitted for 2 inch for 2 inch wet vent up to to the 1.5 inch vent 2 inch on one side for a washing machine and a 1.5 inch for a sink!
Or do you need to come in with two separate tees first the two inch washing machine then the 1.5 inch sink? If that makes sense? Lol
You should post some pictures on our Facebook page.

@@ThePlumbingGurus will do thanks
Great explanation on your codes. Unfortunately here in Kentucky they don't allow any wet venting or flat venting whatsoever... it would make things easier if they did.
Shit that sucks. They’re slowly making it harder and harder to wet vent here actually. I’m sure it’s coming lol
@@ThePlumbingGurus it's kind of dumb. Kentucky code is so strict on venting, but they allow things like putting a san tee on its back (not on side though) for drainage, and min flow is 1%. I get it, kentucky developed its own state code back in the 60s when there wasn't any overarching codes really, but kentucky plumbers can be really stuck up regarding other states code. I can vouch for that as a master and journeyman in KY. Ask any southern ky plumber about working in Tennessee and they will talk absolute shit.
Ya I’ve noticed on a lot of groups, people sure like to bash other peoples work. People need to realize there’s different codes everywhere
I wonder if your plumbing code would be the same as down here as in Ontario..? By the way you gained a new subscriber :)
It’s hard to say. Every province is a little bit different. But in general these wet venting codes are very similar. The best thing to do is call your local inspector and ask them any of your questions.
Forgot one more question if you don’t mind...is it ok to add an additional dry vent to the wet vent? Not required, Just for extra insurance?
You can always add individual vents to whatever you want. The point of wet venting is to minimize the amount of vents you need to run. You used to be able to tie a separately vented sink into a 2” wet vent. But you can’t anymore. They’re making it harder to wet vent now.
When the vanity is vented as you've shown, does venting needing to be 6" above the flood line come into play? My initial plan was to have as your diagram, but also have a vent coming up off the vanity, coming up 6" over flood line then into the vent.
As long as the vent is above flood level rim you should be fine.
@@ThePlumbingGurus Can a vent pipe run horizontally (slight slope) under the floor? I have a vent pipe coming down through the wall, but in order to get it to the drain, i need to run horizontal for 2 ft. Its for a shower with its own dedicated vent. In this case it is well below the 6" flood line.
Would it be consider a horizontal wet vent wit only the lavatory ?
+Refugio Alonso it would be a drain. But it could be used as a wet vent.
What if you have two bathrooms back to back, do the toilets need to enter in a double Y or can the be two Y connections, one for each.
It can be either or.
How about using a 4" double wye? 4" to pick up the closet, the other side use a 4 x 2 bushing and pick up the lavatory. This is for a half bath.
I would just use a 4x2 wye to shoot for the sink, then a 4” 45 to shoot for the toilet.
Job
Thanks
So you guys dn't have combination fittings? Like a comby..... thats a wye and a street 45.
I'm doing a bathroom in the basement and the vent was not roughed in to the roof. My plumbing layout is very close to your wet-vent drawing. Can I vent back into the vent for the lifting sump?
Hi. Join our Facebook page. The plumbing gurus.
There you can post pictures and we can help you further.
Thanks for watching!
Can the 3" x 3" x 2" wye be 3 inches from the 4" x 3" water closet elbow?
Yes it can be as close as you want to. We usually try to leave some space just in case you ever need to tie in for some reason. But you’re good to go tight
Are you guys allowed to wet vent without the WC meaning tub and lav only
+Plumbjitsu yea we are. It has to be min of “2 wet vent
How many fixtures can be wet vented off the 2” line?
In Calgary Alberta it’s 3 fixture units into a 2” wet vent. So generally just a tub/shower and vanity.
At 7:22 where you indicate the max distance between p trap and attachment to wet vent can not be longer than 6' for 1.5" pipe ( and 8' for 2" pipe) - you explain that for the normal slope, this would be the equal to the inner diameter of the drain pipe. So that I can understand the background behind this - what would happen, for example if we used a 1.5" diameter pipe and it sloped for say twelve feet, which would be two times the diameter of the pipe. Forgetting the code for the moment... if one did this in the 'real world' what would the real 'problem' be that one would have if they actually did this? If this were explained to me - then the rule would be better understood by me.
These are just codes that have been written. It will technically still work in most cases. But what they say is that it won’t vent properly, so then it won’t drain as fast as it should. In the really world yes it will still work and probably be fine. But if you’re to get it inspected, then you would want to put a vent in between and tie it back into another vent above flood level rim. They also say if you drop your trap arm to fast without venting it, it can then potentially siphon.
Hi! My wet vent is about 2.5m or 7-8ft horizontally before reaching my vent vertically. Is this okay? Thanks in advance & cheers from Phil.
What size of pipe and what is it wet venting?
There’s no maximum length for a wet vent. You can run forever
Doesn’t the vent going through the roof have to be 2 inches since it’s for a 3 inch toilet line and other fixtures?
Minimum vents size for a toilet is 1.5” except when wet venting, it needs to be 2”. But once it’s out of the wet vent it can be 1.5”
can you explain how to read a plumbing drawing
Could you be a little more specific please ?
The minimum vent pipe for a toilet is 2” according to UPC in the US, where are you?
We are in Calgary, Alberta, Canada. It’s minimum 2” for a wet vent, but you can individually vent a toilet with 1.5”
You mean maximum is 1 meter or 3 meter... Not minimum...
I didn't get when he said the toilet has to be installed last. Make it make sense, because how are you going to rough everything else in? I thought plumbing starts from the ground up?
We should have been more clear. It all depends on what you are doing. Reno/new build/ addition. Ground works you would start from the trunk line to the toilet. In the joists you would usually start from the toilet. Usual it’s what ever is easiest.
Wet Venting isn't allowed where I live- Kentucky. Neither are air admittance valves or waterless urinals. Interesting to see how it's done elsewhere. Thanks
Always nice to hear other people’s codes too. It’s crazy how different it is from place to place. You would think we could all just follow the same rules lol
So you are not allowed to have a kitchen island with sink or dishwasher?
so i think what you failed to mention here is that your using a 1-1/2 vent only. and that the discharge line has no other vents. i was assuming the 3" toilet discharge was running into a stack of its own. and if that was the case would change the entire possibilities of wet venting.
good solid video tho and the color is great idea

@@ThePlumbingGurus to what end?
What is it you need help with ?
@@ThePlumbingGurus I'll take a picture of the issue and put it up here if I'm able. Basically a 3.5 or maybe 4 inch pipe that goes through basement wall to outside, it's leaking a little and the cement that should be there is gone. Just around that pipe though, the wall is not cracked or anything like that, just the piece where the pipe goes through is gone. Wondering how to staunch and stop the leak?
Much easier to come to our Facebook group. The plumbing gurus, or you can email theplumbinggurus@gmail.com
Has to be a san tee on drain arms as a tee wye/combo creates an "S" trap
Where we are from it is a ty on the vertical and wyes on horizontal. And the vent would break that siphon so the ty is just fine. Since it is going from horizontal to vertical.

+Roch White good choice!
good infor but background noise
Sorry for that
They removed the pulling toilet in the code book in 2017
Sorry what do you mean? To clean out the line?
@@ThePlumbingGurus Yea, I know it seems silly to me as well. But it's not in the Canadian code any more in the national code book. They now want a clean out for the toilet instead of pulling the toilet. I don't understand the rational and I'm probably going do it to snake a drain.
I had no idea they did that, they definitely still let us do it in Calgary. I have never been told that or called on it. I haven’t looked at a code book since the 2005 lol
@@ThePlumbingGurus Yea when I went to nait they made me cross that out in the ILM and make a not in the code book.
U can’t go more than 45 ft using 1 1/2
Sorry what are you referring too? 1.5” wet vent? We don’t use 1.5” for wet venting bathrooms. Minimum 2”
That’s wrong, nothing is rolled up above center line. Two clowns
I hope you know how inexperienced and childish you sound.
