Bilge Pump Alternative


Recommended Posts

Old Bilge Pump by design kicks on when bilge water is nearly three inches deep



New Pump by design kicks on when water hits 3/8 inch deep





Here is a link to a youtube test video

I will test it over this weekend and let you know how it works.

I have ordered a whale non return valve that will keep the water from flowing back after the pump is turned off or cycles off.

Does anyone use a non return valve in the line out of the bilge pump?

here is a link to one, I may add


To keep maybe 12oz from draining back?..... Maybe I see your point now though, the backflow might trigger the pump again and it will just continue to run :crazy: Maybe that's why the factory's trigger at higher point...? For my ballast fill lines I used a 3/4" brass check valve from Lowe's for $9.

How did it work?

Great, I worried about the pressure required to open the valve and it was alot less than the PVC check valves. Just have to make sure you mount it horizontally and buy a couple cheap barbed fittings.

Tested the Whale pump this weekend, rough windy two days on the lake, one minor bow dip into a wave. Overall fairly dry bilge when I pulled the boat out on day two. Pumps much lower than the Rule.
