Thermal overload

Here's the problem I've been having lately.

I have a 30/50 pressure switch and when the pump kicks on and the tank fills the pump keeps running, not shutting off at 50, but reaching about 80 psi and holding there for while before dropping. If I open a tap and let it run, the pump doesn't turn back on when the pressure reaches 30 psi. Instead the pressure continues to drop until the tank is completely empty.

It takes anwhere from 5 to 10 minutes for the pump to turn back on and the above described cycle to resume itself. I checked the tank for signs of bladder damage and found none. Air pressure is set 2 psi below cut-in as well.

I was wondering if this sounded like thermal overload of the pump motor to anyone? Iron concentration is 3ppm. Hardness 50ppm. Pressure switch is new. Thanks for the advice.

Your pressure switch is clogged. Replace the switch and unclog the nipple or the port that its threaded into.

Thanks Sammy. I replaced the switch last weekend but didn't think to clean the nipple. Is this a common problem with well water with high iron content?

Most certainly.Those ports can plug up quite often if you have a mineral content. The reason why it's building such a high pressure is because the switch isn't getting any pump pressure to shut it off. That 80lbs is probably the max pressure the pump can build so thats why the gauge sits at 80 psi. Make sure the air pressure in the tank is set at 2lbs below the cut in pressure of the pump so the tank doesn't empty before the pump turns on. Make the air adjustments with the tank empty.

Thanks Sammy! You're the man! There was a plug of clay/iron clogging the nimple. I had to use a hammer and a nail set to clear it. If I could only get rid of this sediment issue now. Thanks again.
