Here's my Winterization Checklist as requested:
My checklist is for a Park Model, with a residential toilet and water heater, no black, fresh or gray tanks, and no water pump. If you have tanks, pump and an RV toilet you can easily use the pump to winterize your system. Remember to drain and flush your tanks, add a little antifreeze to them, and flush the pink stuff through your toilet as well.
RV Winterization & Storage Procedures For Park Model
Winterizing the Plumbing System:
Turn the exterior fresh water supply hose off
Drain and store the fresh water hose
Drain Water Heater by opening lower drain valve & over pressure
Remove Low Point Drain caps under trailer & open all faucets/shower
Flush toilet, remove all water, sponge out tank, plunge bowl dry.
Bypass the Water Heater using installed valves
Remove Water Filter* in bathroom, and reinstall holder.
*Buy new filter for Spring!
Ice Maker/ Refer:*
Unplug refrigerator cord
Remove lower pump cover on rear
Disconnect wire harness on rear of pump
Disconnect Ice Maker pump water lines (top & bottom) and
Remove (2) screws on pump and store pump at home
Close water valve, and blow out line from sink to maker
*To avoid removing pump, you may leave system together and make pink ice prior to unplugging system. Must be done after lines are filled with antifreeze. You may also simply disconnect the upper line on the fridge, and pump antifreeze until it comes out the end and reconnect to fridge. No need for pink ice.
Reinstall all low point drain caps, close all faucets, and water heater drain/pressure valve.
*If using a compressor to blow air out of system, connect system and blow out each spigot starting with closest to connection. If not, skip to next step.
Using RV antifreeze (2-3 gallons), and a manual pump connected to exterior water port:
Start with closest tap, and work your way out. Lay shower hose in shower base while winterizing it. Winterizing works best with 2 people, and radios.
Open one faucet valve at a time and pump antifreeze into system until it runs pink from each tap.
Pour antifreeze into each sink drain, shower drain, toilet tank, and toilet bowl.
Wait a few minutes, then close exterior sewer pipe outlet blades.
