RODI unit improves tds after dry storage

[franciscosalazar]

I have the Air, Water & Ice - Mighty Mite.

After making 20 gal last week, I forced as much water out of the unit with air instead of fast flushing.
The water created had a TDS of 4.

Today, I started the fast flush and a red/brown sediment rushed out of the waste line.
I let 5 minutes pass then restricted the fast flush for 10 minutes.

The TDS for the water created today reads 3.

Could dry storage have truly improved performance?

So close it's likely within the margin of error.

Or, could be due to colder water temps, which contract/close up the membrane.

Example- Winter numbers are always better than summer.
