Sewer gas smell in house - frozen vent pipe?


Hello,

My friend's bathroom has been smelling, on and off, like sewer gases. We're in upstate NY, and there's at least 2.5 feet of snow on the ground. My thought is that maybe the vent pipe is clogged or iced over, and traps are getting sucked dry due to the lack of venting.

Short of getting on the roof, any recommendations? Would heating the bottom of the vent pipe in the basement possibly send enough heat up the pipe?

Would it make sence to instal a cleanout at the bottom of the vent pipe, so we could remove the cap and blow hot air right up the pipe?

Thoughts?

Add water to all your fixtures and wait for a thaw. Do it every time you flush.

If the vent is clogged you should here gurgling from the fixtures when water is used in another fixture as the water is sucked out of the drain.
Another possibility could be a bad seal around the bottom of the toilet or a dried out trap somewhere that is not being used like the basement.

Tub and toilet don't drain


I have 4 sets of plumbing in my converted barn that were installed at different times. The 4th and newest is not finished. The oldest (1st section plumbing, toilet, tub, and sink), is backing up, not draining. The 2nd section is working fine. We are in upstate NY and it has been unusually cold. We suspect there's a problem with the drainage pipe, where the newest section connects to the oldest section.

Just a thought. If the roof vent is covered with snow, try using an extra long roof rake from the ground to uncover it.

Can you see the roof vent at all?

Have someone drain a sink load of hot water while you observe your vent stack from outside. You will quickly know it your vent is frozen shut or there is a new pope.

Do we need a new pope?
