Over the summer I had a problem with the dockside fresh water port. When connected to the dockside water we found that the water pressure would diminish to a trickle, almost nothing, and then return to almost normal water pressure. When I used boat water system with fresh water pump water pressure was fine. Did a search for kinks in fresh water lines or hidden filters, nothing. Then I remembered that the PO left me some spare parts among them was a new fresh water port pressure regulator. I replaced it and the problem was solved. Question, why do they go bad and are they repairable? Thanks
