Depends on the check valve. I wouldn't trust any metal check valve due to the potential for corrosion. Corrosion could a) lock the valve open and b) ruin the sealing surface so it doesn't seal.
I do like, and have on Touche', a Bosworth Sea-Lect check valve. This is a plastic flapper style valve with a rubber flap. It's worked for almost two decades without issue. I also relocated the bilge discharge to the port side midships from the starboard quarter to decrease the hose run. If I was to reconfigure the bilge pump entirely, I would consider a Ultra Safety Systems mini bilge pump switch and a "water puppy" style impeller pump in a storage under a seat. Dennis C.
