Thank you both, AnnaK and Watermom, after much consideration (and compromise) we are leaving the multi-port on. It is already too late for the pressure gauge as it was having a problem when we were cleaning the pool prior to closing. We thought it was the pump/filter but when we turned the power off the gauge only dropped to 15 so now we are guessing that it didn't like one of these past cold nights. If that is the only problem that we have when we open in a few months I will be happy!
