ok, been a while so lets ee if I can get this all down.
1 - Drain water from your holding tank and remove drain plug in hot water heater. Drain holding tanks ( Waste )
2- turn on bypass for hot water heater ( instruction if needed )
3 - Get yourself some winterizing fluid ( can't remember exact name ) from your local Dealer . 2 or 3 gallons should be good
4- Poor this fluid into your water rez tank. All of it
5 - now go around to EVERY tap in your trailer ( one at a time ) and turn on cold water until water runs pink ( or what ever colour fluid you bought ) Close faucet them do the same for hot water tap. Repeat this at every faucet. Even the ones outside if you have any.
6 Don't forget to flush toilet in water runs pink.
7. Ensure all gas vales have been turned off ( tank vales included )
If you did everything right you should be good to go.
Plz double this list to make sure I covered everything
winterizing rv's and boats and big pools/fountains is what im very busy doing this time of year , so first let me say there are companys out there that's all they do ! look in your yellow pages 4 them \
now some of the services they preform are , drain and flush out all the black and grey water tanks/lines , flush and refill with foodsafe antifreeze the fresh water tanks , using this same liquid purge all the piping to all the water fixtures including toilets , add a rubber protectant to the tires (if has any) regrease and ck all wheel bearings / and wheel brakes if it has any , disconnect and seal all gas pipes from fuel tanks , boats need to have there oil changed and there engines anti freeze topped off , rv's /boats need to have there generators oil changed and there antifreeze topped off/replaced , all food needs to be removed from storage bays (even under seats) and last but not least a seal of some kind needs to be applied to entire outside to prevent animal/pest /water/ice intrusion we use polyester plastic as it can be heat shrinked to fit tight
Double check that by-pass valves are in proper position, as well as any winterizing valve is in the off position. Some units have a winterizing valve and hose to put in jug for winterizing, that needs to be shut off otherwise it will suck air. Back of water heater- lower fitting is for cold water in, valve should be open, and top fitting is for hot out, which should be open as well. Any valves that may be in between those 2 lines such as a "t" between lines should be in off position. Keep in mind, water heater has to fill first before any good pressure will come out taps. I normally open bathtub hot tap because it\'s less mess and let it run until i get good steady flow from faucette, then do the rest, hot cold.
How do I run each valve when winterizing my system? I have completed the other steps, but not sure how to run each valve for a couple of seconds. I have set the system to run all valves for one minute but see no evidence of water draining.
Couldn't find instructions per se, looks pretty straight forward. Take intake line off of pump, install coupling and valve on pump and reattach tank line to valve so that water will be sucked from tank through valve to pump and out to system. Attach hose that comes with kit to valve and it is used to pull antifreeze from jug when you move valve handle to other position.
Winterizing generally consists of draining the fresh water from the engine block and/or refilling with RV type antifreeze (propylene glycol) and disconnecting and removing the battery for inside storage and maintenance charging. Theories vary on whether it is better to change the engine and outdrive oil in the Fall or the Spring.
