Joel We have a diaphragm bilge pump with a Water Witch. Due to the nature of diaphragm pump it does not drain back and this switch does get the bilge close to dry

When the when the switch activates the bilge pump, the bilge is pumped relatively dry. However when the pump shuts off water flows back into the bilge and so the pump is running in an endless loop. I see my alternatives as installing a check valve or installing a different brand of switch. I believe I previously had a Johnson switch. any recommendations Joel 35/3 Annapolis -- Joel 301 541 8551
