Bathroom Stinks?????

POOLMANinCT

hi guys,

my bathroom stinks on humid days..

1. my house is a ranch.
2. 3 full bathrooms, 2 upstairs & one in finished basement.
3. drop ceiling in basement, I removed ceiling tiles & no leaks in any drains.
4. prior owner, re-did bathroom in question himself.

can only detect smell on hot, humid days... seems to be from drywall behind toilet. all bathroom have sinks, toilet & showers or tubs....
thoughts/suggestion?
btw I have been in this house for about 1yr & only noticed this condition about 6 weeks ago.

No complaint of smells but I repaird it anyway.

Is that picture upside down or is the fitting?

rex

if i were to guess its re-vent....its hard to tell though as you can't see the floor or celing

Looks like the picture is right side up based on the sheetrock dust accumulating on the top of the sanitary tee.

Is there a mechanical vent in the plumbing wall? Those have been known to leak after time.

Here's my messy work space on this one. Electrical was being done by the HO. I offered and he said it wasn't that hard.

The WC is under my sawzall blade holder, so you can see the 2" vent is the vertical run. The other vent is for another WC on the other side of the wall. Notice the copper tee (1/2") feeding both. And my other pic was not upside down...LOL

Well at least the concrete wasn't that thick to jack hammer out. Or did the homeowner take care of that.

If you are not positive that the smell is coming from behind the drywall, I would first change the wax seal and see if it still stinks later.

Ron The Plumber

Scum build up in the lav sink overflow can give off an odor, it could be coming from it. Just follow your nose.

Grumpyplumber

Thats a vent connection, I assume.
The problem is the crack above the lowest hub in the PVC tee.
Wonder what kinda glue the genious used on that with ABS?

Tmrrptr

I DID see the crack, first off... then, I noticed there is fall in the pipe to the sanT... Don't know as there would ever be a prob, but replacing the cracked part is always good.

If you have access to a combustible gas detector, like a TIF-8800, they can be used to find sewer gas leaks.
