{Stus-List} Jabsco Par pump failure

I had a similar problem and only had to replace the pressure switch attached to the end of the pump housing. If you open the cover and remove the switch you can bypass the switch and see if the pump still works. Then decide to replace the switch or the entire unit.

  Maybe the diaphragm or piston is stuck.new pumps are not that expensive considering what they do for us.  Try a new one and refit the old one over the winter season.

  Two weeks ago I went out for my last sail of the season on the upper Chesapeake Bay and the Par water pump would not work. This is a new problem and I did not think much about it until last weekend when I went to winterize the boat for the season. I leave Frolic II (1979 36' cb) in the water for the season as the slip has an excellent bubble system and our winters have not been severe for the last few years.  I ususally run the pump to empty the water tank and then add a gallon or so of the pink stuff and pump it through the various outlets in the head, galley, and cockpit shower - both hot and cold. Obviously, with no pump I have another issue on my hands - I was going to the boat today and pump air through the system using the reverse outlet of the vacumn cleaner, unfortunately it is pouring rain and my plans changed. My question to the group is - has anyone had a similar problem with the Par pump and solved the problem? I have a circuit switch on the bulkhead in the galley (in addition to the fuse on the electric panel). I replaced the fuse with the switch in the off position and had power to the switch, when I flipped the switch on the fuse blew. Is there any additional electric breaker on the pump, I do not have the manual and to get to the pump physically is a task that I am trying to avoid.
