Jayco Winterization Question About Pumping Anti-Freeze

Close valve on fresh water tank suction line....don't want anti-freeze going into tank
Open valve on suction hose you stick in bottle of anti-freeze...turn on pump and put anti-freeze thru lines (hot/cold---showers/faucets, toilet, low point drains etc.)

Water heater cold inlet should be closed and bypass valve open (hot outlet valve closed if you have one) so anti-freeze doesn't go into water heater tank
