Dewinterizing

May 20, 2025, 10:21:19 am

As this past winter was the first one we had to winterize the coach. We are lacking any experience. So, I hooked up the coach to city water and ran water through everything. However, When running the fresh water through the Aqua Hot water circuit. It was very, very foamy even after all the pink stuff cleared up. The aqua hot was not on, I however had run the coach to operating temp on the way home from its oil change. So boiler had some passive heat.

The cold side had just a bit of pink and foam and it cleared up quickly.

So just wondering if this is normal.

I get the same thing every year from the AH. It eventually disappears as i run about a quarter tank through. It seems to clear faster when i do heat the water

Have not had to winterize in several years, but when I did, I recall it took quite some time for the foamy-ness to disappear, especially on the hot side.  Continue to flush the system and it will eventually clear up.

I've found the AH dewinterizing takes longer to clear up the foaminess than with a regular tank hot water heater... Typically I dewinterize quick at home before a trip south and don't drink the water or turn on the ice maker. Using the water on the road for a day or two clears up most of that foam.

Once South I sanitize - I flush, let the system sit with some chlorinated water, then flush again...
