Puzzling case of sewer smell only while showering
I have a tiled shower in the master bathroom that started smelling like sewer gas (rotten egg/bathroom smell) but only while showering. The shower is used every day. The trap is visible and is working and there are no issues with any of the other drains in the bathroom.
I've had a couple of plumbers out to look at it but all they can really suggest is putting bleach down there. The drain has been cleaned out and there is no debris or gunk down there. The toilet does not gurgle, the wax seal is intact on the toilet, and all traps seem to be functioning in the bathroom.
I've done a lot of reading on this site and elsewhere on the internet but I'm no plumber so I would desperately like some advice on what to do next.
I think it might be one of two things. It might be the lining of shower was laid flat (house was remodeled in 2005) and so water and whatever has collected under it but I can't see how it would create that distinct sewer smell. It is not a musty odor, it smells like sewer.
The other possibility involves some work that was done on a bathroom almost directly below this one. On a Friday in June, the crew reattached the toilet and sink of a downstairs bathroom after doing a fair amount of work in the room. On Saturday, the shower stunk for the very first time. Is it possible that something the plumber did when reconnecting the toilet and/or sink could be causing this by trapping gas in the drain pipe so the gas rushes back up the shower drain when the water comes on?
This is very distressing so I would appreciate any suggestions on what to do or where to look.:(
Sewer smell in shower drain, and I've tried "everything"!
Hi, Did any of you solve this problem? I have a TERRIBLE sewer gas smell and I have tried everything in this column and then some! I've replaced the p-trap, added a second one, snaked and camered all the lines and all the vents, installed new vents, had smoke tests done, had 4 plumbers look at the problem, cleaned the drains and all the pipes with cleaners and brushes, used bleach, draino, pipe cleaner, pro biotics, replaced my main lateral line, filled the vents with water to detect blockages, opened up all the walls to look for leaks or broken vents -- NOTHING has found the problem! Please help!
The smell comes ONLY after or while running the shower. If I cover the drain and run the water, there is no smell. It's MUCH worse if I uncover the drain and let a large amount of water drain at once. It goes away a little bit if I don't use the shower for a month, but then comes back full force after using it once. Any ideas?
What does cause that smell in your shower?
I have been reading about this Chinese Dry Wall complaints.
Seams the smells are intensified by moisture?
Do you know where your drywall came from for the bathroom?
There might be a link here.
or perhaps it this......
I've been working on my exterior deck and stumbled upon a serve smell from the wet tiles. I'm using slate for my deck and it was not the stone that smelled but the glue that held the smaller tiles to a larger sheet of them. This glue and this mesh smell horrible. Since many tiled showers use mesh backing for sheets the smell might very well be your tiles themself or the glue holding them to the sheets.
If you have extra tile try soaking them in hot water for 90 minutes. Do they fall off the sheet or mesh? Place this sheet or mesh in a plastic bag and leave it a day. Take a wiff in the morning. Does it smell like that smell your trying to track down? If so you might have found the answer....
Rotten Egg smell - Chinese Dry Wall
Inspect one of your electrical plugs our switches nearest to the shower.
Have your wires turned black - this would be a sign of Bad Dry Wall.
