We are one of five families on a small water system that shares a well. There is a small pressure tank at the well and we each have our own pressure systems. A neighbor installed a hose bib on a two inch line several feet from the well and used the hose bib constantly during a construction project. The hose bib was in use about ten hours a day for several months. My pressure system is several hundred feet from the hose bib. I believe that my pressure system was also supplying pressure for his construction since my electric bill was 30% higher during his project. Please explain the sequential draw on water pressure systems located on the same lines. Also please tell me if the well pump could have been damaged by constantly turning on and off because of the use of the hose during construction. We are now getting 5.5 gallons a minute from the system instead of 25.

I would have to inspect this to be 100% certain but I do not see how his draw of water would cause your pump to turn on. What creats the pressure in that tank by the well and who pays that bill, it could be higher. 5.5 gallons per minute only tells me your volume not your pressure. If volume is down there could be an obstruction in the line. How about the other 4 families, having any pressure or volume issues like yours?

The volume was measured at the tank which is shared by all five families. The idea of an obstruction is interesting because the feeder line for the tank was placed under a driveway during construction. The area was graded down and compacted many times with bulldozers and a roller. Can a two inch PVC line be crushed without breaking?

Only slight distortion before it cracks or breaks. Is there any extra silt or sand in the tank? A cracked PVC could be losing a good portion of the water supply. You can isolated the line from the tank and do a pressure test using a compressor or vac pump
