I am back to working on the freshwater pump problem. I replaced the old pump (unknown age) with the same model Jabsco ParMax 1 that had failed and now it is pressurizing the system, so the old pump was definitely the problem. However, the new pump will not shut off, even if left for extended time. I can find no water or air leaks and the system stays pressurized enough to get water from the sink days after running the pump, so it does not seem to have a leak on the outlet side. I am stumped as to why it will not shut off. Suggestions? Dave
