312 RE dewinterize?

[BigBearWV]

So I am getting ready to put fresh water in the new rig. Then will likely have to re winterize it! Long story has to do with an impatient wife! Anyway in the water closet there is a black knob that says winter and a hose connection for winterziation. I can not find anything in the paper work for the camper about this system! Below is a pic of the water works. Can someone give me some in site on this system.

you are suppose to hook hose to it turn on the pump turn to winterize and it draws antifreeze into the system. also there is a bypass on the back of the water heater so you don't have to put x gallons into it. to winterize the wh pull the plug/ anode out of it and let the water drain. to fill the system run the faucet till the antifreeze comes out each one shut the pump off and done. if you want to reuse the af there are drains usually around the console that are the low water drains. put water in the fresh water tank turn the knok to regular/run open the drains and pump it till clear.

there should be a selector for the pump that says winterize. or at least mine has one and they plumbed it backwards, lol

X2. Get a hose end repair that will thread into the connection, get a short piece of hose from your local Home Depot or equivalent (no need to cut up a good hose), place the end of the hose into a jug of RV antifreeze and turn the pump on.
