Mulitble pumps
I have one manual and one Electric, a 3500 GPH in my C-36 witch mostly only gets rain water from the mast in the bilge (The boat is in Portland, Oregon, it rains a lot here). The 3500 is big an only draws the water down to about 1 1/2 inches. I would like to install a small, 4 or 500 GPH pump, and have it wired on a separate circuit or battery. Then let the little pump do the normal duties of keeping out the rain water, etc, that gets into the bilge. Let the larger pump work only if the little pump fails (Dead battery, broken wiring, bad switch, etc.) or is unable to keep up with the in coming tide. I feel the little pump will use less battery power when it does run and it will be able to draw the water down to a ½ inch or so, then evaporation should be able to dry the bilge. But I do not want another through hole, so how can I tee the output of the new little pump into the existing through hole for the larger pump? Boy, are we having fun yet?Bob
