Title: Water Purity
Post by: ian grant on September 04, 2015, 05:49:37 am

The TDS reading (after changing my resin) of my water from my ro system is the same 0.06 before DI as it is after DI I was told that DI should remove the last dissolvable solids is this correct? If it is what could the problem be?

Hi,

The TDS reading should go down again once you change the resin.
Sometimes they do need to run for a little while to get all the old water out the DIs and pipes etc.

I find it gradually drops after a change.

Jase.
