I have about a 18 year old Red Jacket QuickSet Jet well pump model 60RJ 1/2 hp. It sits on top of about a 10 gallon pressure tank. I have a about a 15 to 20 feet deep dug well. Last night after my wife did a couple loads of wash I noticed that the pump was running continuously. I checked the pressure gauge and it was at about 38 lbs. I turned the pump off and ran some water to verify the gauge was working (it was), turned the pump back on and the gauge came back up, and we have water pressure so long as the pump's running. It has a pumptrol pressure switch, which I'm not all that familiar with, so with the pump running I tried turning but nuts on it both clockwise and counterclockwise with no results (pump continues to run). I'm sure that I don't have any leaks or water running anywhere, and the gauge holds pressure overnight so I don't think it's a foot valve issue. Any ideas, suggestions, or other tests I can try?

Your pump can't build up enopugh pressure to shut off. The causes are either sucking air, something blocking the eductor or sucked up against the screen of the foot valve. A single line shallow well jet has the eductor in the wet end of the pump and a two line deep well jet has it in the j-body in the well. Both have a foot valve with a screen on it. Another possibility is a broken or warped implellor.

This is a single line pump. If it was sucking air, which I assume would be caused by a hole or bad fitting in the suction line, it should lose prime when the pump is off, correct? Since that's not happening, can I rule out this possiblility?

Also, I was able to adjust the pressure switch by loosening both nuts so that the pump will now turn off at a lower pressure.

Some air leaks don't leak water. If you have hose clapm type fittings, tighten them. The cause of your problem will probably be one or more of the things I listed.

The short screw nut controls the cut-out and losening lowers the setting. The tall screw's nut controls both in and out and losening reduces both.
