Hello,
We have a lift pump in the basement. Whenever the washer empties, our upstairs toilet
Gurgles up a lot. We've had the septic taken care of and pipes in the basement replaced and it still does this. The vent pipes were supposedly taken care of too. We are stumped.
Any help would be appreciated.

Linda

Hi Linda, Please excxuse the delay.

This is a venting problem that can be cured by venting the lift pump.; Regards, Tom
