i have a question for all the very knowledgeable plumbers here. i want to move a toilet in an old house (cast iron pipe). i want to know if the vents that are stubbed up in a wall with a termination in the wall. i cant think what they are called will work ok? what size? and i am already sure that they are probably not to code. but will they work ok?

Those vents like nice fresh air from a proper roof terminal.

Because toilets have internal S traps and are by design a self siphoning fixture, they will operate just fine with no vent at all. In fact the IPC does not care haw far the toilet is from a vent. Those things "in the wall are Autometic air vents?" maybe. If so you have to provide access to them.

Are you serious?? or are you BS'ing?? I am in an IPC state. A friend of mine asked me about moving her toilet across to the other side of the bathroom, and I told her it would be no problem other than possibly cutting out some sheetrock for the plumber to run a vent to the attic, which scared her off. The house is a ranch, with an unfinished basement, so everything underneath would be easy. Attic access is horrible, however. She wants to move the john so she could have a double vanity instead of the pedestal sink (with studor vent. UGH) she has now. I have a million questions, but I will have to start another thread on this one at some point.

JTRoanoak,

im no plumber but why not use the vewnt stubbed out in the wall. i know im hardheaded, but seriously as a plumber or foot doctor, i see no difference if you vent it in a wall or 1000 feet above the house. a vent by definition is to let air in right? no house at least my old house is so tight it wont let the toilet flush. am i missing something big? i admit i am a dummy! lol

I'm no plumber either, so I listen to what these people have to say. I do know that a Studor type vent is a mechanical device, and mechanical devices wear out. In this case, when it wears out, you get a funny smell, that is not acceptable! Not to mention, sewer gas isn't the most healthy thing in the world to have leak into your house.An access panel in the wall is not cosmetically desireable in this location. I will run or have someone run roof venting for the vanity, and possibly rework a closet to get a vent in for the toilet if necessary, but I will not seal a device needing periodic replacement into the wall, even if my local plumber recommended it. I would rather not vent the toilet than put a mechanical vent in the wall. When I do side work, I sub out plumbing and electrical, and stick to what I know. I might run some vent lines to the attic to make it easier on the plumber, but if its wet, it's his. I am not a Jackleg, and I use this forum so I can learn enough so that no one does jackleg work for me.

I wouldn't ruin the sheetrock, when it was complete you would never know that I was there other than it would be smoother than the rest of the wall!

You can't bury AAV's in the wall. They must be accessible for service.

They are called Air Admittance Valves. You can put one in a wall but cover it with a grill so it can breathe and be accessed if needed (required). But someone was also right stating IPC doesn't care how far away a vent is for a toilet. You can vent two bathroom groups on one 1.5" vent pipe for IPC.
What code are you under in GA? IPC, UPC??? Do you know? GPC Haha or maybe RNPC?

First, you should really check your local code. Some place allow the Studor air admittance valve, and some do not. Besides the issue of eventual mechanical failure, there is another point: They relieve negative pressure on the drain, but do not relieve positive pressure, which can also occur.

Will it work? Sure.
Is it legal? You have to find out.
Will it have problems? God only knows.

MN allowed the Studor vent for *one day* and promptly banned it's use for good reason.
Do it how ever you wish,and good luck.

Most lavs are vented in 1-1/2" unles increased to larger size to accommodate another fixtures added requirements.

Water closets require a two inch vent.

The maximum distance for 3" from the vent to water closet will be no longer than 6 feet(UPC).This includes the riser on the trap arm.So if the toilet is wet vented underneath the tub you could loose another two feet on your trap arm distance dropping you down to four.

And people want to know why their toilet won't flush properly:mad:

Yea, but youse guys have a code that makes sense:D

Actually though, because a toilet is a s trapped, full siphoning fixture it get's it's vent from the bowl itself and any further venting makes no difference, which is why the IPC has decided that vent to bowl distance is unlimited.
