Re: Bilge Pump Check Valve Issues on 2013 Beneteau Oceanis 45
We have a mid-sized Rule diaphragm bilge pump that works so well it will actually clear all of the water out of the bilge and the hose from the bilge to the pump itself. A key element of the arrangement is having a debris filter in the hose between the bilge and the pump. Our pump is placed fairly high in the machine space so that the run from the pump to the discharge is all "down hill". Accordingly, virtually nothing flows back into the bilge without any need of a check valve.
