Folks
I am modifying my waste system this Spring in order removal the miles of unnecessary hose that runs from the head to tank back to the seacock. The 1985 factory installation used two manual valves to direct waste to either the tank, pump out or seacock. When I installed an electric head a few years ago I envisioned steam lining this system to minimize the amount of hose. I am thinking of installing two new ports on top of my tank: an 1.5 inch dip tube directly to the pump out and a 1 inch fill tube from the head. The hose from the head would include two 12v solenoid valves that would direct waste to the tank when no power is switched on: one value closed that would direct waste to the seacock, the other open to the tank via a "T". When offshore the option to discharge directly to the seacock whould be activated via a single switch that powers both valves. Can I assume I still need a vented loop between the offshore "valve" and the seacock? I don't mind installing it but was just wondering since the 12v valve will be closed and seacock shut during sailing inshore. Thanks
