I would like to hook up my jabsco electric head on my B40 to fresh water to both rid my boat of the stink when first Using the head, and to increase use of fresh water so that the tanks are regularly emptied and refilled. Is it as simple as teeing of the fresh water hose from the forward tank on its way to , and before it reaches, the fresh water pump? Is any sort of valve or special fitting needed? I assume I do not have to energize the fresh water pump or use the accumulator tank because the Jabsco head has its own pump. A schematic and pictures would be appreciated.
