After just 18 months of use, the factory installed Marine Johnson Pump (SPXFLOW) went bad on the pressurized freshwater system for the cabin sink. The problem started when the pump made a thump-thump-thump sound all the time even when the faucet was off. At first, I suspected that there was an air leak or loose fitting in the water line between the water tank and pump. I inspected the line and all of the fittings and found no leaks. I replaced the pump with a standard RV pump that I had on-hand and the thumping discontinued. This RV pump was very noisy and not a long-term solution. Knowing that the problem was with the pump, I contacted the manufacturer, who sent me a new pump once I provided sufficient documentation.
I installed the pump today and it works perfectly. My thanks to Johnson/Aqua Jet for a quiet, quality pump and for backing up their product. Gary.
