water both cold & hot shut off 5 minutes while showering

hello, my pump and bladder had to be replaced. Old system water pressure was around 20, my problem is when I went to take a shower after 5 minutes in the water shuts off both cold and hot. Had repair man to turn down the pressure from 50 to 40. Still the same problem, today I flush the hot water tank and replaced both upper and lower elements- retry shower and in 8 minutes water just stops with no warning. I have called all in the phone book and asked a lot of people no one has heard of this. I never had a problem before 2 people before could shower back to back but after new pump and bladder I now have a problem. PS after water shuts off I wait 1 to 2 minutes and water will run for 10 minutes then shut down again. no air problems in any water lines. Thanks for your time.

Without seeing and inspecting what you got, it sounds like your pump or power to the pump is the problem.

It could be that your well runs dry after a few minutes. then slowly refills.

Another possibility is a faulty pressure switch. If debris gets into the pressure switch, it can prevent the switch from turning on right away -- it's as if the switch thinks there's pressure in the line when there isn't. Over several minutes, the pressure in the switch bleeds off, so the switch turns on, pumps things up, and things are good until there's a continuous water draw. I have seen this happen on my own well pump system.

You can troubleshoot this yourself. Open the cover to the pressure switch -- be careful, there will be live, exposed conductors. Wear safety glasses to protect your eyes from electric sparks. Turn on an outside faucet to draw down the water quickly. Watch the contacts on the switch. If the contacts don't close (come together) before the water stops flowing, you have a faulty pressure switch. The contacts should close at the "cut-in" (turn-on/minimum) pressure that the switch was set for, and open at the "cut out" (turn off/maximum) pressure. The cut-in pressure is usually 20 PSI below the cut-out pressure.

If the switch wasn't replaced when the pump and tank were replaced, have it replaced. If it was replaced, you may be able to have the switch disassembled and cleaned out -- or replaced again.

I could also be that the pressure in the bladder tank was not set to 2 lbs less than the low pressure setting.
