After the water softener/filtration/backwashing system runs over night, our pressure tank will not pressurize above 38-39 psi for about, like clockwork every time, the next 24 hours. It used to happen only sometimes. Now it happens every time the backwashing system runs. We have a 550' well, 1 hp sta-rite submersible, 52 gallon State pressure tank, and a 40/60 pump switch. The air pressure in the tank is at 38 psi. I will frequently turn off the well pump at the breaker box during this 24 hour period of pressure/pump ineptitude so that the pump doesn't burn out from running constantly. When the pressure gets down to zero, I'll turn it back on temporarily so that we have [U]some[/U] water pressure in the house. It has no problem pressurizing up to the 38-39 level but once it gets there it's as if something is blocking the road. It doesn't matter what time of year it is so I know it's not a pipe freezing issue. I used to let the backwashing system run at the recommended every-6-days interval but cut that back to every other Friday. Now I only let it run about once a month on a Friday night because I know I'm going to have to be home during the day Saturday to monitor the pump\pressure. And then on Sunday morning when I go turn the pump back on at the breaker box, it pressurizes up to 60 and cuts off as it should and it works fine like nothing ever happened... until the next month when I let the backwashing system run again. I know a 1 hp pump isn't ideal for such a deep well especially when it's almost another 300 feet from the well to my house, and uphill mind you, but it was all I could afford because at the time, which was about 2 1/2 years ago. It was a 1-1/2 hp pump before that I had to replace the wiring too. I replaced the pressure switch at the same time just for good measure. I replaced the pressure tank just a few months before that because I thought it was bad but it turned out to be the pump coming to the end of its service. I had this issue with that pump as well but I figured it was because it was old. Any ideas or suggestions are more than welcome because I'm stumped at this point. Apologies for the long post. I just wanted to include as much info as possible.

We have a well with heating element in it about 30ft away from the well x trol in the house. There's no pressure and no water in the taps. The pressure switch won't build up any pressure either. How do I determine if the pipes outside froze or if it's something wrong with the well x trol. [url]http://postimg.org/image/v5gle7075/[/url] [IMG]http://postimg.org/image/v5gle7075/[/IMG]
