How do I get rid of smell in basement drains? We have 2 floor drains and 2 sub pumps - never wet.?

Answer 1

Are there traps in the drains? If so, just pour water down them to fill the traps, and the odor will be gone. (You'll probably have to add water from time to time as it evaporates.)

Answer 2

The purpose of a p-trap is so there is water caught in the "p". The water prevents sewer odors from coming through the plumbing. If the water evaporates in the p-trap. The odor will come in through the plumbing. When you smell odor, pour a couple of quarts of water in the drains and that will be good until it evaporates again. Don't waste money on bleach. All you get is the smell of bleach as the only thing it is doing is taking the place of the evaporated water.

Answer 3

I don't have a professional answer but I would try bleach solution, 1/2 water, 1/2 bleach. Stronger if you prefer.. There has to be a bacteria accumulation. The bleach odor will dissipate sooner than the bad odor.

Answer 4

I had this once and I used drano extra strength and then a week later used bleach. That took care of it, until the next heavy rain. I think my problem was tree roots.
Best of luck. Granny

Answer 5

Put some water in them.
If the have plumbing like a "p" trap, the water will prevent the gases from escaping.

Answer 7
