Do i need to run the washer on a cycle to make sure the antifreeze is pulled through the lines? I'm not sure i could even get the water out of the drain line as i'm sure it is pooled in there.
As for the girard tankless system, the directions say to simply run the fluid through the system. No cut off valve like the old 6 gallon tank i had on the allegro.
The owner's manual for the Whirlpool front-loading washer states that to winterize:
1. Put 1 quart of RV antifreeze in the drum
2. Run washer on a Drain/Spin cycle
3. Unplug washer or disconnect power
4. Shut off both water faucets
5. Disconnect water inlet hoses from faucets and drain.
I agree with EJM4 that the same would be accomplished by running the antifreeze thru the system. My intent is to run the washer on a cold water cycle until I see 'pink', then repeat for the hot water side. This way both inlet lines are treated, the washer pump will have antifreeze, and any water left in the outlet will also be treated.
** I purchased alcohol-free RV antifreeze (Prestone) since I have read that alcohol may have negative effects on seals and some lines. I don't want to chance damaging anything in either the washer or the refrigerator.
