We have a grinder pump in our hvac room. The issue is the small amount of smell that comes from it when it runs gets blasted around the house because it sits literally right next to it. It is elevated above it but we want to use our basement bathroom without the smell going throughout the house.

Would a fan on top of the vent stack on the roof help get the odor out quick enough?

Would you place the fan closer to the grinder pump to help get it out of the hvac room? We have had multiple smoke tests and nothing else is leaking.

Please help us get our house back!

you need to fix the cause not fix the sympton.
a fan is not the answer.
someone needs to figure out where the smell is coming from and fix it.

We know it is coming from the grinder pump.

Post a picture of pump etc. and maybe we can something ........

the 'lid' of the pump may need to be 'resealed'

bern.. i would think if the lid was leaking there would be a smell when it was filling not when it was pumping.

to me when its filling it pushes air (smell) outwards but when it pumps it is sucking for air.

person says it smells when it pumps ???

? improper cross connection of a condensate line ?

this is a perfect example of trying to diagnose a problem over the internet.

sometimes the cause of the problem is plain and simple.
sometimes (like this one) it needs an onsite visit from a qualified individual.

We have had three plumbing companies come and evaluate. No one can provide a good solution. I siliconed the top yesterday. This AM it smelled terribly after the pump ran. I will try siliconing more tonight but I doubt it will work. Any way I can find the right people to call for this?

Is it possible that a vent stack can be too long and cause a lack of gas exhaust because of how long it is? I just find it odd that it occurs when the pump is activated.

post some pics of ALL the piping including any from the ac / furnace / water heater

I can’t figure out how to post my own pictures! Does anyone have any tips? I have looked at the below information

Where does the white condensate drain pipe drain to? Is there a trap on that pipe?

Have you always had this problem ? Or Everything was Ok and it just started or was something changed/worked on/added etc. and then it started ?

Basically the history of the smell.....

There are 2 check valves near the hvac unit just wondering if they are old or spares
Once the lid is pulled from the crock it should be resealed between the crock and bottom of the lid

AND all the piping needs to be sealed

AND the electric



? is the top wet, or is it merely reflection(s) ?




all / any condensate lines require traps to prevent gas / odor backflow into hvac ductwork - the white pvc is evidently a 'standpipe' into which at least one clear flex discharges

does the tank vent go independantly thru the roof or is something else tied into it ?
