I've had one of this style check valve on both the electric and manual pumps on Touche' for 15+ years without a problem.
https://www.fisheriessupply.com/bosworth-company-foot-and-check-valves-smooth-ends I always thought it was a Whale brand but it looks like a Bosworth. I had the "cycling" problem with the electric pump when I first bought Touche'. The bilge originally discharged under the toe rail on the starboard quarter. Quite a long run. I relocated the discharge to under the toe rail on the port side nearly directly outboard of the pump location. Greatly shortened the hose length. If I was starting from scratch, I'd think about installing a diaphragm or impeller style positive displacement pump and the Ultra Safety Systems mini bilge switch. That would allow the suction hose to be run to the bottom of the bilge sump. Right now the Rule 1500 centrifugal sits up fairly high and doesn't pump all the water out. It would also eliminate the back flow issue without having to install a check valve. Dennis C.
