First I drain the fresh tank and hot water heater.
I blow down the lines with air with the plug out of the heater just to make sure that line is clear of water before I close the bypass. (may not be necessary)
Bypass the water heater with the valve on the convenience center, and a second valve inside the hatch down by the water pump.
Pull the filter for the water filter and replace the reservoir (if you have one).
pull out the white hose from the convenience center, remove the cap, and stuff it in a bottle of antifreeze. (I actually use a 5 gallon boiler fill plastic tank with a valve so I don't have to chase around changing bottles)
Make sure all faucets, drains are CLOSED!
Turn on the water pump with the outside switch to pressurize (use the drains at the frame to purge air). This could suck up a whole bottle.
Being careful not to run out of antifreeze, run each faucet hot, and cold, until pink comes out steady. (I always start with the faucet furthest away).
Put the cap back on the white hose, turn off the pump, and all done.....Unless.....
Dishwasher - if you have a dishwasher, run it through a quick cycle no dry while pumping antifreeze. It only takes about 1/2 bottle.
Ice Maker - if you have an ice maker, turn off the valve under the sink before you start, then unscrew the hose from the back of the fridge (behind the vent). While pumping antifreeze, open the valve under the sink until someone verifies pink coming out, then close the valve and stow the hose behind the fridge. (I actually reconnect it in case I get too excited in the spring and forget to hook it back up and flood my kitchen)
Wash Machine - We have a Splendide and it has simple instructions to winterize it, running hot, then cold while pumping antifreeze for about 20 seconds until you see pink, then running it to spin cycle to drain. They provide a way to bypass the timers.
Pour yourself a little antifreeze - like the charcoal barrel type, as you now deserve it and it's cold outside.
