ro/di question

[jbonez]

is it normal to have 0 tds out of ro before the di resin? i have 88tds out of tap i have the compact lll 75gpd air water&ice setup with dual inline tds meter with a Glycerin Filled Pressure Gauge 1-100 PSI im getting 65 psi into the ro/di unit...

Many of my ro/di units read 0 out of the ro before the di. This is common if the tds is lower than 100 with the use of Dow film tech membranes.

ok cool my filter should last a long time then they are about 9 months now.

This means you have great feed water and your membranes and especially your DI should last a lot longer than the average.
