Hello, thanks for taking my question. I have a home with a well for household water supply. We used to use an above ground pump with holding tank. When that went bad it was replaced with an in ground submersible pump. For several months now grit is getting caught in many of the aerator screens and from time to time the water is a little bit muddy. By now the pipes have been flushed several times and the screens have been cleaned several times also. This issue has not calmed down as we were told it should. Could the pump possibly be a couple of feet too low in the well and stirring up sediments when it comes on... WE NEVER HAD A PROBLEM BEFORE THE NEW PUMP WAS INSTALLED. Any info on this would be greatly appreciated. Thank you.
