Burl-- Didn't mean to confuse anyone. I drained the WH tank by removing the plug and opened the two pull ring low point drains under the sink that drain the hot and cold water lines and the one under the dinette sink that drains the line from the FW tank. I don't have a air compressor so I needed to add RV antifreeze after I closed the drains an the two WH by-pass valves under the sink and opened the third. I wanted to add anti-freeze on the suction side of the water pump and leave the FW tank empty. The white water hose that goes from the FW tank to the pump did not want to come off at either end on the barbed fittings. I unscrewed the fitting on the suction side of the WP and once I had it off the water hose pulled off the barb without breaking. I then put a longer length of tubing on the barbed end and screwed it back on the WP. Put the new hose in a gallon of anti-freeze and turned on the pump. It pumped the antifreeze thru the system. First time for me but I think it went okay.
