I have a sta rite anb-30 1/3 h.p. pump on a well x trol wx-202. It is all hooked up to a shallow well with one pipe going outside. The other night my toilet was making gurgeling noises that where soo violent they made the toilet shake. Then the next night the sounds where coming from the kitchen sink. Then the next day the water started spitting out the faucets and it was black, then it just stopped flowing all together. So I went down stairs and shut the pump off, and primed it. When I turned it back on it would hold pressure until I opened the supply valve, then it would drop to zero, and not build back up. I did this a few times and finally I got it to hold pressure. When I went upstairs and turned the faucets on they ran for a couple of minutes then the pressure dropped and that was it. Any help would be great. I just got laid off and can not afford to pay someone to fix this and my family needs water. Thanks!!
