RO help

[cameronh]

Guys this might be a dumb question.......but I just replaced all filters in my ro and I've let it run for 4 hours and I'm still getting 9-10 ppm.
What's a good safe ppm (obviously 0)?

Measured before or after the DI? Or are you running DI after the RO filter?

Mine usually runs 4-5 after the RO and the DI takes out the rest.

After the di

You know what your water is before the system? Running just a mixed bed DI? One cartridge or 2? BRS has a bunch of videos on it and recently got me to convert to 3 cartridges, one each for cation, anion, and mixed beds.

Before the system is 164ppm,
It's a 3 stage with 2 RO membranes.

Guess I'm not much help. My TDS is higher and it reads 0 at the end. Did you get the new RO filters fully seated in there? I think the BRS videos mention if you don't really get them pushed in they may not seal and some water may be able to bypass the membrane.

I'll double check everything tomorrow and give it another try.
Thanks for your help.
I've never had this issue before.
