I have an undersink water filter that has plastic tubing lines that jerk just a little when water has turned on or off in the house or yard, just so you hear them creak and you know water pressure has changed. Today I've been around the house all day and I have been hearing them doing that frequently throughout the day when I'm not running any water. My outdoor spigots are still closed off for the winter. The toilet's not running. I haven't done laundry or run the dishwasher. Single family home on city water. I don't have a PRV, pressure is fine without one. I'm just curious what would be causing these pressure fluctuations? Does it affect my water pressure when my neighbors run their water? I'm just curious. Is it normal?
