ejection pump vents/syphons toilet
I have a Zoeller 267 ejection pump in a basin in the basement that can be used for sewage but is only used for the washing machine (second bathroom never put in). It is installed IAW manufacturers instructions and has a DOM of 11-99. I have a septic system. I have lived here for about 2 and 1/2 years. The last 6 months when the sump pump runs while doing laundry bubbles appear in the upstairs (main floor) toilet and it syphons water out of the toilet. I cleaned out the pit and remove alot of lint out of basin and off pump. I checked and cleaned the check value which is very rusty. I have snake the main 4" pipe to the septic tank and flushed with garden hose. I have snaked both the roof vent and the vent on the tank to the outside. The problem continues can anyone help me figure out what is causing this. Do I need a professional pipe cleaning or what?
