Sam,
The integral switches are “interesting”. Most of them spin the pump impeller at regular intervals. If they encounter resistance, they continue to run the pump until less resistance is encountered. There is nothing wrong with this approach, unless you can hear the pump from your bunk. I prefer pumps to be actuated by a switch than senses a need for the pump to run.

Anyone have any experience with these? I've got a Whale pump like this, but haven't got around to installing it yet. sam :-) C&C 26 Liquorice Ghost Lake Alberta From: Jake Brodersen via CnC-List Sent: Sunday, March 22, 2015 3:51 PM To: 'Josh Muckley'; cnc-list@cnc-list.com Reply To: Jake Brodersen Subject: Re: Stus-List 37+ Bilge pump Josh, The wiring is certainly suspect at this point in the boat’s age. I prefer to mount the pump low in the bilge because most of them push water better than pulling it uphill. Putting it another way, they blow better than they suck… You’re still going to have the bilge switch in the bilge, why not locate them together? Mine are side-by-side, which makes for shorter wiring runs.

I suspect that it has to do with some of the older wiring becoming corroded and causing a higher resistance. I had this happen before. I'm planning on replacing the Rule 500 with a Whale Gulper 320. I recognize that the capacity is probably on the low side but compared to zero, 320 is a lot and it beats a bucket. The gusher is a single diaphragm pump, can pass debris and has a rated suction lift of 10'. So this means I can mount the pump above the water and have the suction hose run into the deepest and most confined space of the bildge. Hopefully getting the pump out of the water will help prevent corrosion. Anybody have any thoughts or personal learnings? Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD
