So I'll try to keep this short. I have three pits in my crawl space. Ejector pump pit, sump pump pit, and this one. I had plumbers replace our existing sump pump and while they were there I asked them about this pit. Guy in charge seemed to think it was a pit separate made for grease build up. Said back in the day some homes had those installed. He recommended I get a wet vac and suck up the gunk inside, fill it with gravel and throw a lid on it. So taking his advice, I grabbed the vac got in and started sucking it up. My Lord. The stench it released was the worst smelling thing I've experienced. Is it possible it's sewage? And that he's wrong? Should I seek another opinion? I sucked up most of the liquid, now all that's remaining is bigger clumps and solidified stuff. Pardon my ignorance also, I'm just beginning to learn about all of this. Thank you

Only way you could find out it's active or not have someone run fixtures one at a try the kitchen sink first were they mentioned grease when your sure nothing drains thru it seal it up

I’ll guess that it’s active or was recently if it’s stinking like you say. 👍

Grease interceptors (I've heard) can produce the worst god awful stenches. I agree with what's been said so far.

I bet they have separate bedrooms at home, spouses will still smell that stench on them a mile away.
