When I was looking to replace my automatic bilge pump switch, the Water Witch was high on my list of choices until I read this note on the Water Witch website.
NOTE: If large amounts of rain water can enter the bilge, it may dilute the normal, fresh or salt, water outside oursensitivity window. Corrective action can be to switch pump on manually to remove diluted water or toadd minerals such as salt, baking soda, bilge cleaners, etc... NORMAL FRESH WATER HAS AMPLEMINERAL CONTENT FOR PROPER OPERATION. Since the only water coming into my boat is rainwater from the keel stepped mast, the Water Witch was no longer a viable option. Some people who install this switch may not be aware of this shortcoming which can cause unexpected non performance. Ted Drossos Long Island, NY C&C 29-2 (for sale) C&C 110
