Shower Sump Pump starts every minute or so...

[jfboucher]

Seems the shower sump pump (and A C condensation) starts every minute or so for a few seconds, never really empties the sealed compartment. I put a new bilge pump in and a new float switch with same results... Seems the one way valve works fine also.....Any suggestions ?

Thanks

I had a 2006 320 that was doing the same thing as well as a friend of mine with the same boat. I installed a plastic one way check valve (from a hardware store) in the discharge hose very close to the sump box and that fixed the problem. Your check valve maybe be defective or too far from the sump box.
