Low point valve leak- See this thread -current- in Georgetown section. Trekker having same problem with new pump and new check valve.
SHURflo's fresh water pumps have been the industry leader since 1988. These potable water pumps are self-priming and employ three independent
pumping chambers to pump water smoothly and quietly. Built-in check valves prevent backflow into the tank. They can run dry without damage. Their patented design delivers smooth, consistent flow at all ranges of operation, while drawing low current. SHURfloŽ fresh water pumps provide flows from 1.0 GPM up to 3.5 GPM. They are built tough to provide reliable, smooth and quiet operation for many enjoyable years of use. Each SHURfloŽ fresh water pump is thermally protected for added safety and peace of mind. CE versions are available."
Here's why I say that.= The second purpose of the check valve is to prevent shore pressure from over pressurizing the pump. It can be higher and not everyone uses a pressure reducer. Just a thought. The water should not be getting back through your check valve and the pump built in check valve. Here Shurflo brags its self priming and they truly are, slow but it works. The pump is flooded suction it does not pull well when empty however.
