Re: Bilge Pump Check Valve Issues on 2013 Beneteau Oceanis 45
Yes. Same problem. The check valve in my opinion is a bandaid. The bilge in the 45 is recessed and of very small volume. It doesn't take much back flow to fill the small bilge recess. Also the check valve is mounted horizontally, I think ideally it should be vertically positioned.
My plan is to try eliminating the check valve and installing a loop in the hose to retain some water. I have some suspicions though that this will do nothing. The other problem is the long uphill run to the thru hull at the stern. I would like to change the hose length so that I can create an early sharp rise in the hose run followed by a gradual drop to the thru hull.
