I've seen what John is describing many times over the years. Before retiring I would often take a vacation day on a monday. n Sunday the mass exodus would begin and I would monitor the water pressure and the pedestal voltage as they would both creep up and up. Wouldn't be unusual at all to see a water pressure below 40 PSI on Sunday morning go to over 100 psi on Sunday afternoon.

Quality water pressure regulator connected to 5/8" hose and a quality water filter, along with the EMS (permanent mount on ours) for the shore power connection. Never leave home without them.
