Last week wife was washing dishes and water quit, i hit the reset on the pressure switch and it filled back up, about an hour later I noticed no water again. I checked the pressure tank and it had 2 psi. I filled to 28. reset switch and filled back with water. next day no water again. i took pressure switch off and checked the T going into the pressure tank, it had sediment and goo in it so I replaced the T , the pressure tank(20 gal) and the switch(30-50). after that the pump would cut on at 30 off at 40 1 min later cut back on run to 50 and cut off. Someone told me my pump was overheating, so I pulled the pump and replaced it (submersible 1 HP) For a day after the pump was replaced everthing was good. Then no water again. I flipped the switch on the pressure switch and it filled back up. about 24 hours later the same thing happened again. The first time it happened my wife had been washing clothes ( 6 loads) that had built up for the week and I figured it had just run our well storage down.the second time (24 hrs later) no one had been there all down and she started a load of clothes and it quit. I have noticed that when you run the faucet the water pulsates alittle.
