Winterizing the ice maker line

After being almost done winterizing our new 2012 Allegro, I realized that there's a water line to supply a ice maker. Our fridge doesn't have the ice maker but the line is ready to install one. I seems like the antifreeze went through this line but how can I be sure.

If I remove the plastic cap to see if antifreeze will come out, will it be possible to put it back. It seems to be a temp cap until an ice maker is installed.

Any advice

Hello, look under your kitchen sink and see if there is a filter and a shut off valve for a ice maker water line.(I am gussing at the location of the filter and valve) If the ice maker was not installed the solonid valve was never activated to let water through it. It would help you out a lot if you could find where the line starts out inside and go from there. The water valve needs a signal from the ice maker to open up and let the timed water in to the ice maker.I f you do not have a ice maker they might not of ever opened the water supply.

I would call Tiffin's service department, and ask them. I has had great experiences when I called them. I have the 2011 35QBA, and hope you enjoy yours as much as we enjoy ours.

I have the ice maker, and run RV antifreeze through the line and ice maker.

Adding AF to a closed line would still allow the AF solution into the pipe. It would be slightly diluted for that length of the pipe run involved. Still an effective AF solution; but come spring time you're now going to have to figure how to cleanse that portion of pipe of the AF solution.

I doubt if Tiffin could pressure test the system with a temp plastic cap plug. A drain cock fitting is needed there.

The way I do mine is to disconnect the water supply line and place the end of the line in a plastic water bottle when the ice maker cycles - gravity will cause the water to drain to the water bottle. I did the pink stuff one time and you really don't that in your RR fridg filter. I live near Jackson MS so we don't have below freezing temps for more than a few day.

DO you have an ice maker or not?

If you have an ice maker, Then drain the water lines (low point drain) cycle the ice maker, If you watch the translucent line you will see the water "Fall out" Once that's done close the supply valve and then winterize the rest of the motor home.. I prefer the dry medhod (blow the water out several times) but some like to pout noxious chemicals in the line and flush them out come spring.

(Nosious means bad tasting in this context not toxic).

Some even want to use toxic chemicals (Idiots).

(The toxic stuff costs more than the pink stuff does).

But just draining the line by opening the low point drains and cycling is usually enough for the ice maker if you have it.

If you don't have it... I'm not sure you need to winterize, But if you have a line for one but no ice maker, I'd remove the cap and install a standard valve, the kind that you'd use if installing an ice maker (Pipe to 1/4" Compression fitting) and then open the valve to let air in the line to winterize, close tightly and "Cap": the outlet (I'd tape it off with REscue tape) so if you ever get crazy enough to think an ice maker is better than ice cube trays.. You are all set. The valve is NOT part of a standard ice maker kit so you won't even be duplicating effort putting it in now.

Home is where I park it!
