Ok, so I installed a jabsco Par-max 1
about three years ago. I connected it for the sole purpose of showering in the cockpit. I have it connected to a switch so that after a swim we switch it on( it is a pressure regulated pump) and we can rinse off the lake nasties from our fresh water tank. It is only a 1.1 gallon pump and has worked great until today.I flipped the switch and nothing. I checked it out and all it was doing was getting very warm!So, I removed it and dissembled it to find that the armature that the pump cam is on had rusted to the bearing.I have never had a problem before. I have never really drained the pump, I just drained the tank. The pump motor has also taken a toll (looks like the moisture from the pump has damaged the pump housing) but I think it might work again.I have it freed up but it is raining and hard to get back to the boat right now. Warning, That motor was sitting there power on for about 2 minutes before I diagnosed it. It did get very warm to hot. Hope your commissioning goes well!r.w.
