Step 4. Locate the water pump, disconnect the inlet fitting, install the winterizing hose and insert the other end into the jug of antifreeze.	Larger image
Step 5. Turn on the water pump and open the taps, one by one until the antifreeze appears. Do the hot and cold taps at every sink or shower faucet … don’t forget the toilet or the outside shower if you have one!	Larger image
Step 6. IMPORTANT! - Make sure to relieve the water system pressure before proceeding! Turn off the water pump and de-pressurize the system by opening a cold water tap. At the city water connection, pry out the screen and washer, and press in on the valve stem until the antifreeze runs out.	Larger image
Step 7. Pour about a cupful of antifreeze into every drain to displace the water and protect the trap. Finally, dump the holding tanks and pour a pint or so of antifreeze directly through the toilet and the shower drain to protect the dump valves. That’s it!	Larger image
