When we finished our refit
in 2008 I put two bilge
pumps in. A smallish Rule
for regular duty and a $200 Rule
3700 with a 1.5" discharge for emergency
dewatering. Long story short, due to installation
details and the switch/monitor I used, the large pump was fully submersed several dozen times in the intervening years. It cycled on probably two dozen times in 7 years. The motor
has seized. When I opened it up water
poured out. Please correct me if I am mistaken, but a "submersible" pump is designed to be full submersible, yes? Anybody else have experience with Rule pumps of this vintage. Recommended alternatives of similar capacity?
In any case, I won't be taking any chances in the future. My new emergency
pump will be located up higher where it won't touch salt water
unless the boat is going down. And I am not buying
another $200 Rule pump. I bought a $50 equivalent (Chinese?) Seaflow knockoff that is identical even to the mounting basket. I'll let you know how it works in test mode. And I'll post a photo
when I get the install done.
