Hot water tank drain
Lee,You can pull the fresh water intake and discharge lines and the unit should drain.Then when you winterize your frsh water system hook these 2 lines together with a short length of hose that way the non-tox antifreze will still circulate through out the system.You can also fully drain the bow water tank and just put a half gallon of antifreeze in it and run the water pump to get it in the water line to the pump.In the main cabin tank, full drain the tank and then add 1 1/2 gallons and open the head sink fawcett until you see the anti freeze solution come out and do the same with the galley fawcett.The system should be in good shape for the winter.
