I am on a shared well with four other families. We were the last addition to the well. We have our own Pressure Tank, however our water pressure is not good, unless we remove our water filter. we have to change our filter every 4-6 weeks and even when the filter is new the pressure is not great. The other houses on the well don't need to change their filter nearly as often and have not problems running two sprinklers at once when everyone else in the neighborhood is home and we can't even get one to barely turn when no one is home. If we have our own pressure tank why would we have any problems at all? Is there usually a filter that is placed at the main site of the well that is perhaps defective on our line that we have such excess in our filter. Any suggestions on correcting our problem is appreciated.
