Changing out the Alde fluid.

We’re on year 4 now with the new Rhomar glycol in these Tabs. I wonder how many people have actually kept with the 2-year schedule?

Selfishly grateful that some owners are taking the risk and not doing the recommended two year schedule. Curious to see how many years it will take for noticeable problems to occur. It will be interesting to see if anyone who took that risk is willing to admit their mistake if it comes to that.

I look at it like changing the oil in my vehicles at regular intervals. Sure I could go longer and not see any negative impact for years, but I chose to err on the side of caution.

My first exchange from Century to Rhomar took a long time with the learning curve and assembling the equipment for a complete flush. This winter it took less than two hours, but again I tried some new techniques that didn't use the pump system. I expect that the next time, in two years, it will be less than an hour. My 320 only takes two gallons. I purchased the glycol from my local nuCamp service center for $55 per gallon. I don't consider that cost or time to be a big deal for peace of mind.

I'm in Canada and not only is the Rhomar water difficult to source but also very expensive. I also seem to have different fittings from the pictures I saw that have corrosion issues.

If I do start to see some problems I will report back here. As I stated, this is a risk that I'm taking and I'm not suggesting that I hold the truth.

As a car mec, thank goodness Alde did not make my car heater system .  I would much prefer to have the heat come up a little slower  (built with thicker metal) than have the mess I now have with the boiler leaking! Art

DISPOSAL   - - - - Our sewer plant says do not flush glycol, I called to inquire because our polypropylene is supposed to be safe.  The city environmental person said a home owner with several gallons of polypro glycol can flush it.  Just not Ethylene glycol.
