I have a Goulds J5SH 1/2 hp jet pump sitting at the base of a 500 gal storage tank which is filled by a submersible pump from the well. It is connected only to irrigation. We were out of town with some freezing weather expected so I shut down both pumps and bled the lines from the pump shed to the irrigation system. When we returned two weeks later, I turned on the jet pump and started the irrigation timer. I forgot about the submersible and when the 500 gallons was used up, the pump ran continously for 36 to 48 hours until I caught it. It was pretty hot to the touch, but when I introduced water, it cooled right down and sounded totally normal thereafter.
But instead of holding 50 or so pounds of pressure while the sprinklers are running, now it is holding about 35#, although it still does recover to the 60# set limit when the spinklers are turned back off. So, did I:
1. Ruin an impeller?
2. Plug a filter I don't know about inside the pump when I sucked up the last of the water?
3. Something else?
And is there a kit I can order to get it back to normal pressures if needed? I am pretty mechanical, just unfamiliar with this pump.
Appreciate the help.
