I had a periodic problem with water coming in the bilge pump under certain conditions. It seems that when the bilge pump outlet was under water, usually when motoring, water could flow under pressure through the bilge pump. This seemed not to be a siphon, but a water pressure situation since it stopped when the boat slowed down (making it difficult to diagnose, of course). I installed a check valve in the bilge pump line and the problem stopped for several years. It happened again last weekend while motor sailing in swells, so I am planning to replace the check valve. I vaguely remember someone suggesting a particular brand of check valve as working particularaly well, but I can’t find the post. Reviews I have seen on various sites have complaints about all of them, so hard to choose. I think I have the Whale no-return valve now. Anyone have a brand suggestion? Thanks- Dave
