#2102, "RE: 2 way bilge pump for a cooler?" In response to In response to 0
I run a transom mounted pump to fill my well and a second pump inside of the well which recirculates the water. I've installed a y-valve in line on the internal pump with a second hose off the y over the gunnel to pump out the water. When I want to pump the water out, I simply close off one port of the valve and open the second which empties the live-well.
