I have a winterizing valve that you turn and a hot water bypass valve, but when I turn the winterizing valve, I don't know where to put the af to pump it threw the lines, can anybody help
Turn your CITY valve to CITY, WINTERIZING valve to WINTERIZING, the pump will pull from your CITY hookup. Put a short piece of hose to CITY hookup and the other end into a bottle of antifreeze, turn on pump.
