GARY C :

Hi my name isXXXXX will do my best to help solve your problem

GARY C :

Is this actually a sump pump? (for ground water) or is this actually a sewage pit?

Customer: T is the sump
Customer: Dont have a sewage pit
GARY C :

If this is a sump, the only may have a sewage smell, would maybe stagnant water, sitting in the sump basin, Your idea with bleach would be a good approach, you may wan t to take a shop vac and suck the pit dry, then fill the basin with water again and add some bleach. If you still have the problem i would suggest using a sealed lid (cover for the pit)

Customer: I have a seal on it
GARY C :

you have a lid? or a sealed lid? a sump pump usually has a u cut in it for the discharge pipe which would not be sealed

GARY C :

If it has bolts on it its probably a seweage pit

Customer: Could I have a break in the sewer line
GARY C :

and there is a gasket that is supposed to be between the lid and the pit to seal it

GARY C :

If it is a bolt down (sealed lid) the gasket is not there, or the gasket is bad

Customer: It's a lid
GARY C :

You can fix this by using silicon on the bolts and the rim of the lid

GARY C :

It sounds like this is a sewage ejector pit and the seal is not there or is bad thats why you have the smell, seal the bolts and the rim with silicon

GARY C :

Also where the discharge pipe leaves the pit lid, and where the power cord leaves as well

GARY C :

any break in this will cause the sewer mell

GARY C :

smell

Customer: Is it used as a sump to cause it takes the ground water out
GARY C :

No matter what you have a sump or sewage pit you say it has a sealed lid, There has to be a bad gasket if is truly a sealed lid (no holes where you can look into the pit without un bolting the lid) then you just need to caulk the rim, bolt holes, and pipe's with 100% silicoln

GARY C :

Do you have a sewer pipe in your basement that go's out the sidewall about chest levl? or at least above the basement floor? im talking about the sewer not your sump pump?

Customer: I'm sorry I was wrong it's just a black plastic lid
GARY C :

with a u cut out around the discharge pipe? meaning you can look into the pit throught the u without removing the lidd

GARY C :

and the lid you can just pull off, its not bolted down?

Customer: Ya
GARY C :

ok your right its just a sump pit

GARY C :

again you should not have any sewer smell, i would first shop vac the pit out, then add some water with a hose again and add bleach

GARY C :

Then if you still have the smell maybe add a sealed lid with a gasket or silicon

Customer: Done that an the small just comes back in about a day
GARY C :

You should not have sewer gas so yes it is possible you have a sewer break and its going into the foundations draining system

GARY C :

which ends up in your sump (and thats the smell)

GARY C :

If everything is flushing good (plumbing) i would just seal the lid, I have not seen a sewer break result in what your describing (but that does not mean thats not where its coming from)

Customer: So I'm going to be writing a big check to get it fixed
Customer: So I should seal it first
GARY C :

Try what i suggested, but if it ends up down the line that it is a sewer break, you looking at a tractor digging up your yard (would have to be just outside the foundation wall or it would not end up in the sump) probably a $1000-$2000 job

GARY C :

I would think you would see backups if that was the case

GARY C :

seal it first

Customer: Ok I will try sealing it first
GARY C :

If the line has collapsed you should have backups, just make sure you seal the lid first, if you have backups from the sewer i would suspect a pipe breakage or collapse

Customer: That is what I thought that it was right out side the wall
GARY C :
