Just moved into a house last month. A musty smell comes up from the double kitchen sink drains when you pour water down there. There is no garbage disposal. I tried pouring clorox down the drain, it works for a few hours but then the smell comes back. It’s not a very strong smell, but I definitely know its there. There’s no leaks under the sink. I am sure the smell is coming from the drain.
Anyone know what causes this or what I can do to get rid of it? I’m sick of using candles to mask it instead of just treating the problem.
