Please help if possible. My pool will not hold a prime .When I turn the knob to pull from the hot tub it will start for about a minute then stops. When I turn knob to pull from skimmer no luck. I have tried replacing o ring on backwash valve, placing water around pipes to see if it would prime due to a leak but no luck. Should I have it all redune? I am at a loss on what to do. Any help is appreciated.
