Bilge Pump Discharge - New Thru Hull ???
Run separate, properly sized hoses for each pump. The single line theory is good until it gets knocked off or screwed up at the end toward the thru hull. Then all pumps on the line are useless. Redundancy, donchaknow. I put a Rule 360gph automatic at the bottom of my 5'' bilge. 8" higher I put a manually switched 1500 gph. There''s also a whale gusher, each on separate lines. Skip the Rule float switches. They seem to go to crap on a regular basis, even the more expensive "waterproof" ones. The 360 auto I have (I don''t know if they make it any more - they might only have the 500) draws very little amperage and has done so since 1994. The float switch problem I''ve noticed more and more after moving to the Caribbean and replacing switch after switch on friend''s boats. Further, hoses and bilge spooge and spooey can lay across the things and keep them from activating. KW
