I have a 2006 Hunter 45 CC,. The aft shower and sink drain into an "Atwood" sump with a float switch pump, which discharges overboard. My problem is that the pump constantly cycles on and off due to the backflow draining back into the sump. I have added an inline backflow preventer, but after so many years it too leaks. I am sure that this setup is common on a lot of other Hunter models. Question; Has anyone changed over to the "Whale Grey IC Shower Waste Pump Kit"?? I believe that the 12-volt model number is WM 8284. If not, has anyone changed the system so as to prevent the recycling? Any and all ideas welcome.
Thanks,
Jeff
