Phosphate readings in RO/DI water-what's to blame?
So, it's time to replace the sediment filter, the 3 different carbon filters, and the DI
resin. So my question is, does the DI
resin remove Phosphates (I'm getting about 1ppm) from the water, or is that the RO
unit? The RO
unit, per recommendations of the company, should be replaced every 2-3 years. I was just wondering if it was the DI
resin or the RO
that needed to be replaced. I'm assuming the DI
, but I wanted to check first. Thanks!
