"Funky-ish" odor from sink. What could it be?
About 3 months ago, we had a kitchen renovation completed. Included in the renovation were a new double-bowl sink and new dishwasher. The new sink is about 24" from where the old sink was situated, so the sink plumbing was shifted accordingly.
About two weeks after all was completed, I started noticing a strange odor at the sink. This odor did not exist before the renovation. It doesn't smell like rotten food and it doesn't smell like a decaying animal. It's hard to describe it except to say it's mildly funky. At first I thought it was coming from the dishwasher, but I notice it even when the dishwasher is closed. Another thing I should mention is that after the water has been running for a short while, I no longer notice it. Maybe my sense of smell is just adapting to it, but it seems to go away when the water runs.
Can anyone help me identify the source of this odor? And, more importantly, help me get rid of it. Thanks!
