Hi, I work in an office and we have two bathrooms. one we use as storage and dont use the toilet at all so there is no water in it. Well we came in this morning and it smelled like someone cut the cheese :eek: !!! I went next door to see if they had the same problem and they did. Well I called the property owner and then realized that it was coming from the unused bathroom for some reason. He came and said that it was because we need to flush that toilet every once in awhile, that the gases build up in the wall....is this true????

I'm no plumber but gasses shouldn't build up in the wall unless there is a break in the soil pipe.

I am a roofer and I have fixed this sewer smell a few times by removing birds nests from the top of the soil pipe, which was clogging the pipe.

No. Gases can escape through drains into the room if the water that is usually maintained in the trap, from regular use, evaporates over a continuos period of non-use. Gas does not "build up in the wall". Run all the bathroom fixtures for a minute and see if that doesn't fix the problem.

No, gas is not building up in the wall, that is just plain silly. Basically what is happening is that water is evaporating from your traps and letting the sewer gas up through the toilet. You should run water in it every once in a while to fill the trap back up. Trust me on this one, I've seen it before and I'm very smart. :Thumbs:

Its not so much that you need to flush the toilet, you just need to keep water in the toilet bowl to keep the trap working properly. Can I suggest that you just have the toilet and other plumbing fixtures removed and plugged up so you can properly use the area as storage? A lot easier than stacking boxes on a toilet! You can easily plug the fixtures while allowing them to easily be hooked up again in the future.

You need to maintain the water level not only in the toilet (in the bowl) but in the bathroom sink trap as well in order from keeping the sewage gases from coming through.

We had this very same problem in our guest bthroom a couple weeks ago. My wife even called the "honey dipper" to see if they could come and pump our tank. Thankfully it was 3-4 times the cost down here in the KEYS as it is in VA, so we thought about it for awhile and bingo! We thought about the traps and how the water may have evaporated. After running a little water in the sink and shower, no more problem.

The septic people also wanted something like 200.00 to come out and "inspect" it. I would be that they knew exactly what was wrong. At least they should have!

Regards,
Paul

Also check for floor drains, they dry out as well and allow sewer gas to enter the building. Had one once where the floor drain was covered by some shelves, but still was open enough for the smell to come in.

Hasn't anyone else noticed that this thread is 1 year old. Digger has brought a whole bunch of threads back from the dead here in the plumbing section.
