A water Witch switch does not need as high a water level to run your pump as a traditional float switch. Is also not mechanical so less prone to failure. We have this switch mated to a diaphragm pump and this leaves very little water in the bilge as the diaphragm pump pickup is very low.

You can set the level switch higher in the bilge so that it only runs when the capacity of the gusher is exceeded. For what it is worth I was in a pinch and ran to Walmart LATE one night after the local chandleries were closed. I bought whatever they had (IIRC it was branded as Johnson with a 3 year warranty, 1200 gpm). It has lasted more than 3 years and considerably longer than the Rule pump which it replaced.

I mounted a Whale Gusher and it does a much better job of sucking the bilge dry than any of the centrifugal pumps that start picking up air earlier and then cannot pull any more water out. Those always seem to allow a lot of backflow, and a backflow preventer valve only adds restrictions, thus slowing the flow. Though the Whale Gulper is not rated nearly as high from a gallons per hour basis, judging from the time it takes to empty a nearly full bilge I get the impression that its real life performance is nearly as good as the small centrifugals. Just my $.02 worth...

I mounted them High and dry in a locker and was able to suck the water out with hose led into the bilge. If you can make the pump you high point and go gravity from there, you might actually be able to get the water level down very low with little backflow. I have to say, it is nice getting the pumps and the wiring out of the bilge. I plan on doing this same setup someday on the tartan.

I am looking for a replacement that has the water level switch in the pump. There are lots of these for sale, but what is the list’s recommendation? The old pump is a Shurflo (sp?) 355-100-00, rated at 1000 gals/hr<http://gals.hr/>, - the label says it draws 7.35 amps (but I haven’t measured it). Is Shurflo even made any more? I see Rule pumps and lots of brands I have never heard of on line. The automatic pumps I found online leave about 2 inches of water - is that the best we can do? And what pumps last well?
