I have a submersable pump thats about 3 years old. I was told its around 400 feet deep and that its a 4" well. I recently added a water softner and ever sence then, I'm hearing an air sound when running the faucets or outside hose (not all the time). And now my sprinklers won't work. I have a small system that just feeds around the house and it worked fine till this? As far as I know there is no leaks and the gauge holds around 50 psi. I hope my well isn't going dry!! My neighbors wells are fine. Any ideas?

Just made my second failed attempt at getting a shallow well installed. The set-up is a sand point laid out with a 3ft point, 1/4" galvanized pipe (now at 30ft deep), good drive couplings, a "t" , a check valve, a Rand 3/4 HP jet pump. There is water at 25 ft down, in the pipe, which I have blown out with a compressor and air hose until water bubbled out clear. Question: Should I have put water in the pipe and observed that the water runs down, into the water vain, to confirm weather or not I am in good water? I didn’t think to do this. Or should water stand in the pipe, which I should have filled prior to connecting the pump? I have tried a hand pump which hissed when disconnected (so it had build some pressure), and tried hooking up the pump (primed, primed and reprimed and tried to bleed air out) running it for up-to a couple of minutes. It would not build over 15psi. When pounding the pipe, I tightened the couplers and pipe every couple feet, and used pipe tape, too. Not sure what to try next. Any advice is Greatly Appreciated!!!
