Question of if complete winterizing is necessary

[sthomasaz]

My wife and I bought some property in Eastern Arizona. Our plan is to leave our travel trailer there. We will be there every few weeks. It does get below freezing during the night. I was wondering if blowing out the lines was enough or do we need to go through the whole winterizing/dewinterizing process every time we go there.

I'm assuming we probably have to, but I was wondering if anyone else in a similar situation has gotten away from having to do the complete process.

On a related note, In the de winterizing videos I watched, they do a sanitization process as well as flushing out the anti freeze. I'm assuming this is because it has been sitting there for several months. If I am winterizing/dewinterizing every few weeks, do I have to sanitize as well?

I never sanitize but I also don't drink the water. I do my best to maintain clean tanks.

?offgrid? Private well? No well? Electric? No Electric?

I may have an answer for you. Publication removes patent options, but then maybe that is not that important.

It has a private well and installed septic. No electric yet.

I drain the fresh water tank and water htr., blow the lines and RV anti freeze in the ptraps. I don't sanitize, I may reconsider if we relocate to South Sudan.

There are lots of people who only blow out the lines. That is NOT foolproof. It only takes once to ruin you day/week/month. The pink stuff is cheap insurance.

Yes, anytime the water system is setting idle for an extended period, it should be sanitized, even if you are from a chlorinated source. Chlorine breaks down over time and ceases to become effective.
