    Describe Problem_Just in the past week we are experiencing pressure drop. Simply running bath water pressure will drop to less than half of normal until you shut it off and let it refill bladder tank. Pressure switch seems to be functioning normaly. First noticed issue a few days ago when our Geo-Thermal unit was running and we couldnt get but a trickle out of kitchen faucet. Faucets run normal if nothing else is going. Geo thermal unit is a Hydro Heat Mega Tech model 03-090-WTAR-TS-AT. When it is running in heat or cool mode at max flow its pulling about 10-12 gallon per minute. I think problem is well related not geo because I can shut unit off and problem is still there. Well is about 6yrs old and Pump was upgraded with larger bladder to a 1hp pump to run the Geo unit 3 yrs ago. Any ideas would greatly help!

    My guess if you have a hole in the pipe somewhere, probably right above the pump. You need a clip around amp meter on an incoming line. If it is pulling 9 amps, you have a hole in the pipe. If it is pulling low amps, your pump is not doing as much as it should.

    Default hoe in pipe?

    Not doubting or questioning your knowledge but how would you get a hole in the pipe? Could it be caused by wires rubbing or what?

    Maybe he meant "leak" as PVC is less likely to develop a hole like steel pipe might.

    Default voltmeter readings

    I borrowed a voltmeter with a loop. I had 8.7 reading on the red wire. Is that close enough to 9 or is 9 a firm number?
