I have a 3/4 hp 230v submerciable pump matching control box and new pressure reg. tried 4 pumps and all have same results, pump start cap. kicks on and kicks off, even if i use air to see if tank gets pressure it wont. water seems to make it all of 95ft but doesnt make it to tank it actually got water to come out low and slow but not more than 10 min. or so and at less yhan 10 psi on the tank. could the tank stop the pump from staying on.? the tank is approx.6 ft. high and I could ptobably wrap my arms around it.
