I have a problem that I don't know how to address. When I turn on the faucet, flush the toilet, was clothes, or take a shower, air shoots out with the water. I don't get the amount of water I used to in the same amount of time as I used to. We live in the country, have a private well and have agricultural wells (approx 1/4 mile) to the north and east of our house. We had our well drilled and pump installed in 1997. The installer called the pump a white water system. What could be causing this and what can I do to fix the problem. The installer of my system is no longer in my area.
