Dirk E Redding , CA December 29, 2020 Diverter valve seal started to fail and was leaking water onto the floor. Needed to replace the entire sump since the model has the seal as part of the sump instead of being able to replace just the seal. Nothing to difficult, just took pictures of everything before disassembling. Just have some towels handy and dish soap for lube. Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
