I purchased a brass Y with cutoffs on both legs from Lowes. At Camping World, I purchased 2 white six inch long hose extensions. Also bought a quick disconnect for the water hose. Hook one extension to the city water fitting and the other to the black tank wash fitting. Hook the Y to the two extensions. Connect the water hose to feed the two legs. Use the cutoff valves on the two legs of the Y to alternate between your water supply and tank wash. When I wash the tank, I learned to NEVER EVER NEVER leave the valve open and walk away!!!! ALWAYS make sure the DRAIN VALVE for the BLACK TANK is OPEN. Sewage from the black tank can and will enter the camper and make a mess that never leaves.
