Winterizing 2003 Coachmen Aurora

Greetings....first time winterizing and instructions say "remove fitting from suction plug" (which is NOT labeled). I am thinking this is the plug / fitting just to the left of the city water inlet. Anyone familiar with this unit? It has theFive Valve Water Works Panel. Appreciate any guidance so we can get started. Thanks.

Welcome to the forum! I have a 06 Coachmen Mirada with the Water
control panel as well and just finished winterizing! I'll try to walk you through it.
If you have the manual availble go to the "Plumbing Section" on page 41 which gives you a picture of the control panel!

Easy steps to follow;
1) Set valves to drain fresh water holding tank
2) After drained, close off valves and set to the "Winterize" position
3) On the righ hand side of the panel, there is a "GRAY" plug threaded
into a hose fitting! This is where you attach the siphening hose for
adding the pink antifreeze. NOTE: The siphening hose is available
from you local RV/Camper dealer.
4) After attaching the siphening hose, place the other end into the
pink fluid container. With the help of another person, turn on your
water pump to charge your system. During this process, you must
open each fosset one at a time to; drain the water from the lines, charge
the lines with the pink fluid until you see the pink coming from the fixture.
5) Once the system is fully charged including the kitchen fasset and the toilet,
pour additional pink fluid down each drain to fill the individual traps.
You might want to drain your outside shower as well
6) I used approx. 1 1/2 gal of pink antifreeze @ $1.99 ea

Hope this helps!

Great post Ed. Ken, Don't forget to by pass the hot water heater and drain the hot water tank. Remember the ice maker if you have one and also plumbing for washer if yours is plumbed or has the washer. Make sure you run the pink stuff through the toilet sprayer.
