While it would not be my choice, if you do decide to install a check valve, 
install it where you can get at it. They do stick shut sometimes, and for no 
obvious reason. Happened on a boat that I was crewing off the west coast of 
Vancouver Island. Nearly changed out the electric pump before we thought to 
check the check.

  Subject: Stus-List Automatic bilge pump switch help


  I replaced my automatic bilge pump switch with a waterwhich. When the when 
the switch activates the bilge pump, the bilge is pumped relatively dry. 
However when the pump shuts off water flows back into the bilge and so the pump 
is running in an endless loop. I see my alternatives as installing a check 
valve or installing a different brand of switch. I believe I previously had a 
Johnson switch. 


   any recommendations
