RODI cartridge

[Tomoko Schum]

Hi y'all,

How often do you replace your RODI filter cartledge? Although I am still getting zero reading on my TDS meter (the tap is 50 ppm), my output pressure has come down a bit. I don't think my main water line pressure is down, though.

do you have a flush kit on the filter? the membrane could be clogging up.

I have a push button test on mine. Green light OK, red light replace it. It usually lasts about a year.

Most systems are set up to read pressure on the INPUT side of the RO membrane - are you certain your's doesn't?

With the pressure gauge installed on the input side, the most common cause of reduced pressure is clogged prefilters.
