Maybe you could pull the hose up to the deck where it comes through the hull
and make a loop. This might break the siphon. My discharges are just below
shear.

Subject: Stus-List Bilge pump siphon
Hi. 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.
