In May I posted a problem I was having for a long period of time. In short, my water pump (Flo Jet) would not stop running after the battery dropped a few tenths of a volt. After spending much money trying to resolve the problem (I was told bad batteries, bad hoses,bad converters etc), I finally found a local rv repairman that did the fix. In my original post, I mentioned that the Flo Jet service man said there is no way to adjust the pumps and sent me a new pump. The new one was worse. What my repairman did was adjust the pump with an allen wrench at the set screw on the front of the pump, much like Shurflo suggest adjusting their pumps. Wa La!, now my pump stops crisply after each use even as the battery drops in voltage. I'm going to write a letter to Flo Jet.
