Questions and answers
Hello, Foul water from my toilet rises into the show tray before the pump kicks in.
Foul water from a toilet rising into the shower tray before the Grundfos pump activates could be caused by a blockage in the main drain line. If the pump does not activate quickly enough or if the waste cannot drain properly due to the clog, sewage can back up into the lowest fixture, which is often the shower tray.
