Anyone having issues with recent membranes from Dow not lasting very long?
I put two membranes in not too many months back and have usually pre-DI TDS of 4-5. Today, the pre-DI TDS after the membranes reads 10.
I imagine this is an issue with the RO membranes and not as much an issue with the prefilters? The prefilters and both membranes I changed prior to making maybe upwards of 300 gallons of product water.
My RODI unit has the following order:
Sediment > carbon > carbon > chloramine monster > RO mebrane 1 > RO membrane 2 > mixed DI resin
I have the unit running through an RO buddy booster pump. I forget the microns of the prefilters. I believe they're 5 micron sediment, 5 and 1 micron carbons.
