Did you check the water in two places?
1. Coming out of the RO
2. From the final stage of processed water coming out of the DI
I did not use to do this and I probably threw away a perfectly good RO
memebrane when all I needed to change was DI
resin. The RO
membranes last awhile. Since then I switched to this: Dual inline TDS meter DM-1 HM Digital - English
so I know exactly what needs to be replaced, plus you never have to break out the old TDS
meter because it is always hooked up.
