Sewer gas coming from washer p drain

kaciiiJune 9, 2010

We don't have a washer and just moved in. The laundry room started smelling like spoiled milk. It is really bad today. I ran a hose into Pdrain (as there isn't a washer hooked up.

Will this help? Don't think a washer has been hooked there for over a year.

Yes. That is likely the problem..your trap was dry. All your drains should have water run through them. Dont forget any floor drains.

If your not using that drain you should pour about a quart of water in it monthly to insure the trap stays full. After you pour the water in you can also pour a couple teaspoons of cooking oil in the drain. The oil will form a film over the water and retard evaporation.

Mineral oil (the stuff at the drug store) works better since it does not go rancid like cooking oils.

Mineral oil with added fragrance is marketed as baby oil in the US, UK and Canada.

This is from Wikipedia. If you don't already have this in the house any grocer carries it.

Keeps the water from evaporating.
