Had a plumber replace my basement sewage ejector pump after failure, he “upsized” to a bigger pump. Ever since then, when the pump runs, it causes siphoning (gurgling sound) from a ground level bathroom sink and sucks the trap dry so sweage smells permeate the house. The sewage ejector pump discharges into a pipe along the side of the house, which then runs right by the outlet for the ground level bathroom.
1. Is it possible the plumber “over-spec’d” the ejector pump, and its just too big for the system?
2. How can I test the adequacy of the air vent for the upstairs bathroom? Maybe it is blocked? I’m not even sure which stack on the roof belongs to it, but I think it is a 1.5” air vent.
3. If the u/s bathroom vent is clear, and the pump isn’t over sized, any other solutions to this? Someone suggested I try putting a bigger trap on the u/s sink drain.
I welcome any troubleshooting ideas or solutions. This is a smelly problem and the installing plumber is saying the issue is with ventilation and not their install or the pump. I’m not arguing with them, just want to get to the bottom of this one way or another.
