Had the pit been used yet?
Note to self...
When fill checking the dwv plumbing, don't forget to plug the vent line between ejector pit and the basement floor drain..
I needed to mop the floor anyway...
Are you saying that the basement floor drain vent and the ejector vent are the same? You wouldn't get away with that here - the sump is supposed to be vented separately if you don't want the pump to siphon traps.
I think he was saying he was filling the DWV system for a leak test and he didn't block the vent for the pit... When the pit filled and the pump went on it got ugly fast!
The inspector has not seen this yet.. Did I goof? I could not fund much specific info on vents for ejector pumps. I just made sure the vent and the ejector pump outlet were the same size (2") to be conservative.
There is no way the pump could siphon the traps even if the tank and fixture vents are connected together, and that is the way we have done it since the beginning of time.
