shallow well pump and tank problems/tank will not fill
Hi, I need help, I can't get water to pump into tank. I bought a new pump and tank but it still won't work. I have a 19 gallon upright tank with air value on top and one hook-up at the bottom of the tank. And a 1 hp, 800 watt, 60hz, 10 amp max, 3/4, 120volt, 23 to 50psi, 23gpm max water pump. I've tried the recommended air pressure in the tank, I even let all the air out of the tank but nothing worked. The fossit is about 40 feet from the pump. I have a shallow well. The pump works/ primes fine because in a few seconds all the lines get cold even the line going to the tank, which let me know the water is there but it will not go in the tank. If I go to turn the fossit on ,water and pressure comes out fine until all the water is out of the line. Pump kicks on again until it fills up the line and then it kicks off, still no water in tank.Why is there no water going in tank?
