Hi Paul, Everything that adds resistance reduces the capacity of your bilge pump. Check valves and small diameter hoses reduce the capacity of the pump. You have to be very careful about using a check valve because of that.
I have two bilge pumps on my boat, A small-volume one at the lowest point in the boat (inside the keel sump stub) and a high-volume primary one about 8" higher in the engine compartment. I do NOT have a check valve on the primary bilge pump in my boat. Be thoughtful about your installation... be safe out there.

I had a check valve on our old boat, but hadn't gotten around to on the new boat. I had been a bit hesitant since most folks say don't, but if Judy's got one on her boat, I want one on mine. --- In ic...@yahoogroups. com, Sonshingle <sonshingle@ ...> wrote: > > I also have a Rule 2000 pump and know what you are talking about.
