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.

[@NiceMuslimLady]

@@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.

I guess things have changed now in 2022 with these fancy newfangled porcelain devices but I still like the way toilets were ‘vented’ in 1922 - there was a louvred vent on the back wall of the outhouse and you just left the door open for a few minutes for cross-venting.

[@oldtimefarmboy617]

One thing I would like to see addressed would be vented covers for the vent pipe that exits the building. As a custodian for 25 years I have seen times when the wind is blowing from the right direction hard enough, it will create a suction on the vent system strong enough to actually pull the water out of all of the traps. I have actually seen a toilet gurgling because enough water had been sucked out that it had become low enough that the air flow could not pull more water out but not so low that there was an open space for the air to flow without going through a small amount of water. The best traps in the world do not amount to a pile of packing peanuts if your sewer vent is sucking the water out and leaving a path for sewer gas to enter the building after the wind dies down.

[@spiritualistgirl]

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??

[@oldtimefarmboy617]

@@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.

[@oderusurungus4438]

Sometimes a "wye" fitting won't work because the Joist space is too short and may possibly be more expensive as you need to use a 2" 45 fitting to make it ready to plumb the vent vertically. The most appropriate fitting in this instance is a 3x2 "tee" on it's back. If backwash venting/ wet venting then a wye is most definitely in order.

Funny how this was on my timeline. I did Vo-Tech in carpentry for 3 years. We remodeling a home for training. I got the master bathroom. The instructor said this is your Budget and this is the code book. Code books are easy. 2 things. Minimum size max size. Min 2” max 4”. Done. But venting toilet problem. Instructor told me about this venting and said all other vents to it. I Learned this back in 1987. The instructor said what the video talked about. Why do you see odd things like a 3 inch vent pipe or in some cases a 4 inch vent pipe. If you have the room run one or two of them because somewhere in the codes you can only have so many vent pipes in to one. Like in the bathroom bathtub , 2 sinks , toilet all into a little 1.5 or 2 inch vent pipe that would not pass codes because if all of the appliances are running at the same time it ends up not being adequate venting. What was I gonna say he’s the instructor.

[@rupe53]

... 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)

[@jameslowmanjr6141]

@@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 KZbin 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.

[@tonyturner487]

Only issue I see with this is you should never reduce in the direction of flow. With that being said, it should be 3” or 4” full size up to the closet flange. Additionally, you’re able to use a tee rather than a wye long as it is a vent only. Could help in the event you have tight spacing for said vent.

The 4x3 closet bend is used in probably 80% of homes in the U.S. Agreed that you should never reduce in direction of flow but the closet bend is an exception and is made for this very purpose.

[@jpapajcik]

Ohio follows IPC. We are relocating a toilet about 8 feet from its current location and hoping to tie into the existing vent for ease. The vent stack is currently in the wall directly behind the current toilet location. Our code states: 909.1 Distance to trap from vent: Each fixture trap shall have a protecting vent located so that the slope of the developed length in the fixture drain from the trap weir to the vent fitting are within the requirements set forth in the table. Exception: The developed length of the fixture drain from the trap weir to the vent fitting for self siphoning fixtures, such as water closets, shall not be limited. Is the EXCEPTION what removes the distance requirement? We just need to be sure before we continue. The toilet will be about 8-9 feet from vent stack. thanks you!!!

So glad I only do permitted remodeling. I get to plumb according to what works based upon my multi-decades of experience.. Obviously there is more than one way to make it work...the code books offer at least 2 different ways.

[@joshcowart2446]

I was told in CE that UPC got rid of the toilet limit on 3” and just bases it on dfus. I haven’t look in the code book to verify yet because it’s usually irrelevant as I always run a 4” main anyway except in specific situations. As for the unlimited trap arm in IPC, is there an exception for flat roughing or for toilets because there is a limitation on trap arms. In IPC (the best code for trap arms) it’s based on 1/4” per foot fall. If the trap arm has this slope then at a certain point it will be an S trap. So you divide the ID of the pipe and multiply by 1’ and this is you max length. 3” would be 12’. The upc has seemingly arbitrary numbers. 1 1/2” is 3’ 6”, 2” is 5’, and 3” is I believe 10’. I do commercial so we mostly stack rough so there may be some exceptions I’m not aware of. I didn’t know if the length was allowed to be longer because a toilet is anti-siphoning

[@daddy1571]

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.

[@joshcowart2446]

@@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.

[@daddy1571]

@@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.

[@joshcowart2446]

@@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.

Every state has different codes regarding venting/back venting. And you can not reduce pipe size as the flow goes. Meaning you can’t go from 4” to 3”. That would be an immediate fail

I was going to watch this video whilst on the commode, but I didn't want to cause a rip in the space-time continuum. 😅

What do you do, if cut existing old DWV that goes through roof and “DON’T” add a new one? Do you cap the “cut old DWV” thru roof; so water doesn’t collect inside and/or pool under a slab in grade foundation? FYI: had contractor help out w/ bathroom remodel and they had sub do plumbing and they ended up digging up slab as flipped toilet and vanity and added a tub and extended existing shower (which they had to dig 2 times after finished since during flood test 1, forgot to connect drain, & flood test 2 forgot to connect drain to exist 🤦) that was there. After all said and done, and pouring concrete 1 time, 2 times, and busting up to fix mistakes before poured 3rd time; which on 3rd time, they STILL DIDNT VENT ANYTHING IN BATHROOM TO “OLD EXISTING” VENT THRU ROOF 🤦. So, when time for final inspection, guess what, found that wasn’t vented to code, but they able to “fix” w/ adding 3 AAVs, argh. But what am I supposed to do w/ the vent pipe coming thru roof, cap it so water won’t enter and pool under slab etc….or rodents, or “nature crap” etc… Thx for vid and everything, cheers✌🏻

Why did they use a Studor valve rather than connect it to the existing VTR? There's something that you aren't telling us. A contractor "helped" you to do the remodel? So...did YOU do it, or did you actually HIRE a contractor to do the whole job, or what? How much did YOU do, and how much did the contractor do? I'm a bit confused by this.

Well if you aren't using the roof vent and it is not hooked up to anything on the bottomed then yeah, cap it and the next time you do the roof, delete it.

What is the purpose of venting a fixtures with a trap? Will the fixture function without a vent? How many bends can the toilet drain pipe have?

[@gwot]

when looking at a T or Y is the 3rd dimension always the T/Y part? 3x3x2 for example, the Y part is always the last one?

THANKS

[@bubbavox]

Thanks for all the great resources. I'm assuming this is Sketchup -- what do you use to model drain pipe and fittings? In the past I used 'pipe along path' which simply converted lines to pipes of chosen diameter.

[@txmade4371]

Since when does a 3” or 4” pipe need a vent?

[@carultch]

Other than "because the code says so", what is the theory behind how plumbing vents are sized?

[@JohnMiller-ee9pn]

You should have made mention of the dry vent rules for the DIY pro.

I have a vent already going through the edge of the roof of the back of the house. I'm moving the soil pipe to a side of the house as I am building a single storey extension. I wonder if I could use the top most part of the existing vent by connecting it to the new soil pipe by running it around the house along the wall. Is it allowed and is it something I can do? The existing soil pipe and vent runs straight up from about 100cm from the (outside) corner of the building in the back of the house. We are to move that to the side of the house about the same distance from the same corner of the house. So the new pipe will continue from the ground up to where it connects to the first floor toilet and then straight up (vent) and instead of creating a new hole through the roof on the side of the house, bent the vent pipe towards the edge/corner (100cm), bent it and run it along the back wall (100cm) and then connect to top part of the current vent which already runs through the roof and opens above the roof.
