Steven, On my 37+, the discharge points are a few inches above the waterline, but the hoses leading to them loop up well above the waterline to make sure no water can come back in when the back of the boat is heavy.
Check your hoses and make sure they go upwards. Also, I have, in the past, used check valve on bilge pumps without any problems. Good luck. All the best, Edd ------------------------------- Edd M.

I have a 34+ and had an unusual thing happen this morning while at anchor. I woke to the sound of my electric bilge pump cycling on and off. The bilge was full of water. I turned the pump on to drain the bilge and it filled up again once the switch was selected to off. I had the same result with the manual pump. When I removed the manual bilge pump hose from the bilge and then turned on the electric pump again, the bilge stayed dry, so the water must have syphoned in via the manual pump discharge. The discharge on this boat lies only a few inches above the waterline, but with any weight aft, it is below the water. Has anyone else experienced this? I understand check valves are not recommended. Thanks for any advice. _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com [email protected]
