How To Vent & Plumb a Toilet (in 2024) 

Re check your information from 5:15 about the IPC code regarding 3 toilets. Check the footnotes of table 710.1(1). There are footnotes on allot of these tables that are basically exceptions to the rule. Hope that helps your future study.

Actually, I stand corrected. That is my local IPC code. You are correct about the National IPC.

So in Santa Maria California, is it IPC or UPC

@@ahci9585 california is UPC. Santa Maria may have additional codes

Union?😅 Chicago still requires 3"x2" tee to vent a toilet. Most counties got different codes.. u should mention that. Venting by Wye u can add a sink to this vent and make wet vent..

Yeah we always use 2 inch

I hope you're not being serious.

Does it necessarily have ti be a closet bend or can be a long sweep 90 ?

You died of dysentery.

I bet spiders bite you alot

Perhaps your outhouse is already on wheels, but when I read that you moved it, I immediately imagined you picking up one side and pulling in on its wheels, 😆.

I mean, without a vent that outhouse I'd going to stink

😂👏👏👏

Lol thanks and blessing to you as well,

Good to hear

Thanks.

Water Closet need not be vented This is one fixture unit that do not require to be vented

@@tab529 It CAN be done...but, there are special conditions required for it to actually be useful. If you have a high water table, for example, a ventless WC won't work well...unless you don't mind your bathroom smelling like a sewer. If your WC is on an upper floor, the long drop can cause problems because of the lack of venting. So...you might end up having to go back and installing a vent for the WC anyway.

Thanks David

Don't fall for this horrible advice.

​@@Hammerpedia when venting is it on to vent at an angle, so it could go up wall instead of right in middle of bathroom

👌❤️

Thank you sir.

i have a prob. its windy and the walls rumble, and the vent PVC stack..is vibrating..loud..but my parent n partner cant hear it??.. infra sound? it iiss that.. as i emptied all the tanks, toilet and turned off mains water.. its out of alignment..maybe leaking on the roof/???.. any ideas??

@@spiritualistgirl The range of men's hearing is different from the range of women's. Like the eyesight of insects that feed on flower nectar range into ultraviolet and some predatory animal's eyesight range into the infrared. If the wind is blowing hard enough to cause your walls to rumble there is most likely nothing you can do to prevent the PVC stack from vibrating either. You would either need to build a wall that blocks the wind or make major modifications to the building. A vent pipe vent cover is not going to fix what your problem is.

This is the orfice effect that carbs on small engines and old cars used. There are ways of siphoning using this same effect.

How about a STUDOR VENT?

Bullshit. Vents pull air in and release it the wind will never affect a vent the wind will only affect gas appliances. Studor vents only allow air in not out.

... up north they don't get too strict on the vent size inside the house but going through the roof MUST be at least 3 inches because the more water flows the more likely it will frost up in the winter. Yeah, there's lots of older homes with 1 or 2 inch vents and those are probably single bath houses.... AND... it seldom goes to -20 outside.... BUT... that's why we have a new code. (because some DO freeze up)

@@rupe53 I had to do some work on my septic lines. Went outside where the bathroom was started walking around kicking the dirt poking the dirt. It should be a four-inch pipe that comes off and comes right up to the top of the ground somewhere in this area. Nope not the case. This was like two years ago three years ago. My neighbors like what are you doing. Digging a hole running another check and vent pipe. He shaking his head. Well I got it all done. I see this on RU-vid about a month ago two months ago I can’t see when I posted. Maybe it was just a post from a state that said they change the codes or something. But I was always taught when I was in that field that’s how you run your vent pipes. As soon as I put mine in my wife comes out of the bathroom and goes what did you do to the toilet. She says it sounds like a vacuum cleaner when you flush it now. I said I eliminated back pressure lack of venting I allowed the water to go where it needs to go without any restriction so it creates a vacuum in the toilet bowl now. Because how fast the water is leaving the toilet. Now it’s a good thing because when we put the new environmental lesser water toilet in. It will flush perfectly.

You are welcome!

They have one way check valves for vents that may be worth adding for the sink. Also the main sewer line vent may be too small.

@@adamplummer2190 I do have one through the roof-- looks to be about 2" pipe. I plan to tie in the washing machine, tub/shower, & toilet to that vent but the kitchen sink, lavatory, and other bathroom groups in the house will have their own separate vents.

@@catsmeow5566 make sure if it goes sideways it's above any water points or it can fill with stuff. May need to be snaked.

@@adamplummer2190 Yeah, all vents will be vertical for minimum 6" above flood level. For the ones not connected to main vent they will have their own individual vents that go through the wall, follow it up, and then elbow around the eaves and then elbow again to go above the roof. That is how the circuit vents are done. I am considering some AAVs for some of them since there is at least one atmospheric vent. The AAVs would be accessible for maintenance/replacement. Might need an AAV for kitchen sink specifically bc there is a window less than 6" above and if I tried to angle it around the window I'd hit electrical.

Ask a master, the always Cary the upc code book, I’ve been plumbing 40 years. Journeyman plumbers can only do a limited amount of work. A master plumber is required for any plumbing company

Thanks

Good question. I know that a WC waste arm was 6' maximum in our old Oregon Specialty Plumbing Code book,but they switched to UPC the last update! It's unbelievable. The things you're allowed to do,like running 4 WC on one 3" waste line. 8 WC on 4" too. I run 4" mains as well. It's just as easy as 3",but you're covered in case of fixture overload or additions.

@@daddy1571 I work with upc everyday in Austin and as far as I know it has the same 3” 3 toilet limit. It is limiting with trap arms. We didn’t have any maximum for a wc trap arm. It was just the trap arm length for whatever size you chose. UPC, though seems to have completely arbitrary trap arm lengths. Like 5’ for 2”. I don’t know where that comes from. In IPC it’s 8’ based on the fact that when graded at 1/4” per ft you have 8’ before it’s an s trap. As for using 4”, when I started that’s all we used. I started in a small town. We one hardware store with a decent selection but still limited. The rest of our stock got delivered once a week. For this reason we only ran 4”. It automatically cut in half the amount of stock you have to keep. I only used 3” on repairs.

@@joshcowart2446 Small towns are good places to grow up in. Probably what makes you a great plumber lol!(I'm from one too) I got a diagram from my city inspector that shows 8 WC on a 4" line. As long as you run vents between the last WC and your first WC you can run 8. Circuit vented branch is the specific name that it's called according to the diagram. I used it on an underslab rough this year. You just can't use combos looking up for your WC(I asked but the inspector explained why it couldn't). You have to turn them on a horizontal grade,then 90 up for your WC.

@@daddy1571 yes I agree. Just in terms of plumbing I can think of how small town people are better. In the city, everything is an emergency. I’ve been called out for an emergency that turns out to be not at all what I would consider an emergency. Small town people, due to not having 24 hr plumbers available, know how to deal with things. They can get by until a plumber can get there. They either know more about how to do things themselves or they’re much more willing to make due. As for the circuit vent, yeah I’ve never actually done one but I remember being taught about them. I thought you were talking about sewer pipe sizing. I don’t know how the Oregon code is but from what I hear from lots of plumbers is UPC is stricter than IPC. I have to deal with both so I should know the differences because Austin is UPC but every city around Austin is IPC. The only thing I can think of off the top of my head is the UPC is more strict in terms of trap arm length. The rest I’d say they’re more similar than they are different.

Australia only uses 100mm or 4 inch for all toilet piping. Vent pipe 50mm or 2 inch. All toilets are dual flush.
