Um, how would I check that ?
Just to clarify it is ONLY the shower causing the smell. The sink has no stench. The washer and dryer has none.
I got to thinking last night, I've heard some people talk about the trap being dry and what not but now I am wondering, the wash machine hasn't been used in a LONG time.
Basically, we closed May 2. I am gradually moving things over. Big move day is this coming Saturday. However, the house was vacant for a few weeks before closing and even then, it was just the previous owner's kids slowly coming and clearing out their stuff. Possible that the wash machine hasn't been used in well over a month.
Could there be some sort of "shared" system, whereby the wash machine needs to stay active too ?
