Unwinterizing, found Alde Rhomar level low....normal?

CanadianTabber · April 2022

Hi all,
I just dewinterized my 21 Boondock 320 and found the Alde fluid (Rhomar) level
very low in the reservoir.
Is this attributed to normal evaporation, as I see no areas of leaks anywhere?
Is it normal to top up the reservoir on a regular basis?
My NuCamp dealer says they can order in a gallon which is no problem but I plan to take a three week trip in a month and not sure if it will be shipped by then.

Thank you!
Brent

How low is very low? A little evaporation is normal. However, as a comparison, we still have Century in our 2021 400, and I've only had to add maybe a few cups in the two years we've owned it. At one point it was maybe 1/2" below the low level mark. We also live in an extremely dry climate and have had very little evaporation. I'm not sure if the Rhomar behaves differently. I'll find out when I switch out the Century in a few weeks for Rhomar. Did you notice if any glycol has drained out of the drain tube or is there any that has leaked from around the Alde unit?

The level is below the minimum mark but slightly above the bottom...I am not seeing any leaks or fluid anywhere so i assume it has evaporated.
The Rhomar iI believe is thinner and more watery than the old fluid. The drain tube has some moisture within it as if it has evaporated this way.
Will order some Rhomar, fill it and see.
This is the problem with such a complicated heating system.

@CanadianTabber - not sure which “drain tube” you are referencing, but if the auto air bleeder valve in the flow assembly gets stuck in the open position, you can lose glycol.

Hi Sharon, I am referring to the tube in the foreground. Seems to be fluid in the tube as if

it is evaporated fluid.
Which is the auto bleeder valve you are referring?

@CanadianTabber - it comes off the Alde. Check out this discussion: https://tab-rv.vanillacommunity.com/discussion/comment/184519#Comment_184519
