Well here it is that time of the year for us non-South bounders WINTERIZATION TIME
The first move is the RV anti purchase pink stuff no other. 4 gals mine will take have two toilets two black tanks 1 gray and plumbing for washer dryer. No washer dryer. What to do Washer-Dryer
NEXT I go around and open all faucets kitchen, baths, showers in & out, plumbing for washer and remove water filters sink, ice maker combo and main filter.
Close valve for water line to filtered faucet on sink and ice maker, disconnect the water line to ice maker, let water drain from ice maker itself, had previously defrost the refer and shut off refer. Cleaned water out of ice maker container with sponge or paper towels to dry and open switch arm to back drain water in line with lines disconnected from water valve in back of refer you can blow out water from this valve, after water out of lines will tape so no little creatures can get in.
This water line from filter under sink to faucet and ice maker will leave disconnected all winter.
NEXT go to all low point drain valves I have four, two in water bay and one each on both split water tanks both sides of coach in compartments where you can see fresh water tanks. The two toilets let water seal in bowl drop into tanks you will reseal with anti at end of operations. NOW close all faucets you opened before, before going outside.
The water heater is drained by removing anode rod plug bottom of tank open relief valve and let water drain. Check your rod if eaten away you may need new one, mine was still in tack, new this year and will reuse next year, cleaned and wrapped in paper towel and store in HW bay.
Turn your by-pass valves, three of them, to the opposite direction from summer use. This will stop anti from entering tank. I have a long yellow plastic wand to clean out bottom of tank of sediment that may collect there. To remove remaiming water in tank use a siphon to remove if you wish.
NEXT find a large bucket to hold two or three gallons of anti and fill. Shut off valve to fresh water tank siphon to water pump and open valve to plastic hose. REMOVE brass plug on end of hose and place in bucket of anti. Go to water bay and turn on pump you will see pump suck anti up hose and open the two low point valves until you see pink stuff and close. OPEN the exter- shower for pink stuff your done outside.
NEXT go inside with a small container and open each faucet slowly and allow any water to drain into container to clear, clear water, when pink shows shut off and go to next faucet and so forth. I throw clear water outside and double check each faucet for the pink stuff. The toilets, operate foot pedal and also spray hose if you have one for that pink stuff. I have to add another gallon in bucket outside you maybe OK with the two gallons.
Once you have this done take remaining anti and pour in all traps all sinks and ample amount into all toilets and sinks so anti will be in back of all your drain valves in water bay and leave a ample amount in toilet bowel.
Well that should just about do it just DO NOT FORGET to remove all can goods liquid containers from storage cabinets and you will not have a mess in spring time when you will do everything in reverse.
One other thing shut off switch for LP DETECTOR up in your tank display area so as to not drain chassis battery.
People that do not own Newmars will have same drain points on their coach but some what different. Fleetwood fresh water drains on older coach's had one large drain off tank, Atwood
water heaters do have problems with by-pass valves. Atwood parts
If anyone has questions about their particular coach feel free to ask plenty of answers on IRV2.
