Plumbing vent

[skihuckster]

Didn't find this in a search of the forums. Has anyone dealt with plumbing codes and specifically, the main vent on the drain system? In a typical framed house, the vent goes through the roof but that's not an option for a yurt. The codes are damn specific and not compatible with yurts.

I can think of plenty of ways to accomplish this functionally and my place is remote enough the plumbing inspector may pass anything for want of not coming back, but I'm curious if anyone here has dealt with pluming inspectors and if so, what did they allow or not allow?

I will post whatever I learn but if I can leverage others' experiences first I'd like to.

That is going to depend on your location.

You will probably have to contact your local inspector and get his/her take on this. As an FYI, most who have a yurt, especially if they live in it, have a wood stove. The pipe goes either through the tono or the side. Ours goes through the side and can be sealed enough to be safe. Note sure if that is an option. That is a question you will have to discuss with the inspector.

Not on a yurt. But around here inspectors cut you NO slack at all. The gov't wants no lawsuits against them, believe me. One of my mantles flunk because the top was>> >1/4"<<< too wide per spec book that came with the insert. I sh%$ you not. 1/4". I wanted to kick that dudes a$$ into next week.

Well that's not promising.

Since my deck is off the ground I was thinking of teeing my vent off the main drain where it will exist under the deck structure and bringing the vent pipe over to the stove pipe and using that support to also support the vent to a proper elevation. Yes I could run it out the wall through a grommet like the stove pipe but I prefer not to.

The inspector has no idea what a yurt is. His inspection will probably be the first time he's seen one.

More than ideas I'm looking for any examples of when folks on this forum did it wrong and didn't pass. If I fail inspection I hope it's on a design that hasn't been tried/flunked before.

Wish I could give good advice here but I'm no plumber. I do know when I built our house (year 1999 codes applied) there had to be a vent stack directly up and through the attic and roof, within 10 lineal feet of any/all drains. Sink, tub, toilet, shower, clothes washer, dishwasher. If it had a drain, 10' max to stack. Of course there was a stack size minimum diameter as well.

The dude that plumbed my house was a pro plumber friend and he was real upfront about what he had to do to get everything to pass inspection. I didn't get gigged on plumbing. My own work did though. But that's another story.

One thing I’ve seen is folks running the vent pipe out through a wall instead of the roof. I know a guy who plumbed his own cabin like that, and the inspector didn’t bat an eye.

I had forgotten about this post from 2y ago but can update on the final result, which passed a couple months ago. I vented all my sinks with an AAV indoors (behind an access panel on the bathroom wall). All the drains went below the floor and combined into a stand pipe that drains to the septic tank. Off that stand pipe I put a Y fitting and extended a 3" vent sideways (to clear yurt wall) and then up to a point 10' above the floor elevation of the yurt. I supported it the same way many support stove pipes on yurts.

That satisfied the inspector without arm twisting. I had to deal with a pair of them: one wanted the 3" vent, the other thought 1-1/2" was more than enough.

IMO the inspector signed off on your 'custom' vent because it was a one off install that was gonna work fine regardless of the code spec.

Residential subdivision around here they wouldn't have. I got gigged on 10 items. Some were BS. And some weren't. I'm especially glad the inspector caught a basement 'form step' violation of 6' drop where 4' was maximum. The day before the pour.

Plus I caught another foundation form mistake myself where the foundation morons missed a counterfort clearly marked on the plan. That would REALLY have screwed up my front deck and roof foundation at the front of the house. It would have cost >thousands< to correct. Effing illegal morons led by a foreman that couldn't have cared less about the accuracy of his work. I had an entire set of trusses rebuilt over the laundry from that dumbass building the footer 8" on the wrong side of a foundation line.

Of course the items I got gigged on in my carpentry work were total BS. lol

If you’re stuck, it might be worth having a pro take a look. I’ve had to call in help when I hit a wall (pun intended) on stuff like this.

You're fortunate to have a cool plumbing crew that speaks English and understands what you want them to do.

Why would I sat that? Nowadays around here, you'll quite possibly be talking with a foreman that's bilingual. What you actually want done can get lost in translation, or dropped simply because because the crew is gonna roll the way they want. What you want is unimportant. "We doan need no stinkin badges!" lol

The crew does what the foreman tells them. He may not be telling them what you want because he knows you don't speak their language. You can be standing there talking what you want with the foreman and watching the crew doing something else. I've had that happen. Nowadays in construction, bilingualism is a real problem.
