Why would there be a sewer smell coming from the basement? There is no leaking of water.?

Question

Had recent plumbing replaced and no water is leaking in the basement on the floor. No flooding either.

Answer 1

A dried out u bend (water trap), to a sink or toilet, would let sewer gases come up into the basement. Do you have an inline pressure release valve on a drain pipe going into the sewer. If you do: it could be malfunctioning, jammed open or actually brocken. They are a bad idea ALL sewer vents should be vented to the outside. This is for your own safety and health.

Answer 2

I lived in an older house. It started with the smell. The sewer pipe had cracked and was leaking sewage in to the ground under and around the house.

The problem needs to be found before it gets worse, and like the previous answer, itis very dangerous.

Answer 3

Sounds like a drain trap has dried up. Try pouring in a few cups of water to refill the trap. To keep the trap from drying out again for a long while put a teaspoon of mineral oil in the trap to reduce the amount of evaporation.

Answer 4

Checking the floor drains for a water seal and each and every of the P traps are an outstanding idea. You did not element out a washer connection. Do you've one downstairs? each and every of the traps must have water in them. It sounds very very like a venting subject. (drain & vent) try this; briefly "cap off" your kitchen sink. perhaps for 2 days. (water & gas tight) Have your moms and dads do each and every thing up stairs countless situations. nevertheless getting an scent? this is no longer the KS. next try the WM connection., the lavatory basin, the tub or bathe. try the technique of eliminating idea. once you locate it, settle on how you are able to re-plumb it to prevent the scent subject. solid success.

Answer 5

You probably have a drain somewhere in the basement and the smell is backing up from your septic,if you have a septic. If you do, it's probably coming from bad bleeder lines. And Baby's Mom is right, it can be fixed and it is dangerous! We had the same problem and it cost a bit to have it fixed and we didn't have grass for a while where they dug but it was worth it.

Answer 6

do you have a sink in your basement?
if you do, maybe it's because you haven't used it for a long time, and there is no water in the sink pipe, so there are things building up, that's why there is a sewer smell.
so let the water run for a bit, maybe that'll help

this happened too at one of the classroom at my school.

I've had the problem before, it was leakback from the sewer lines, it can be fixed, and it can be dangerous.
