Which output on this membrane housing is the product water output?

How should it be for a dual membrane setup? I took mine all apart and not sure if I have it right now. I'm getting 0tds out of it so I'm assuming I have it right.

Unit is about 5-6 years old so I think I have your old style flush kit installed on ot

Ok, cool. I would check out this video here. It's a step by step on installing the second membrane :)

What's your TDS at?

hejjo · Mar 4, 2016

450 TDS.

Ahhh, bummer. Yeah that is a little too high for the dual system. Do you have a water softener? If so and you aren't running your RODI downstream from it I would recommend doing so :) That might get you down to where you need to be for a dual membrane setup.

I know right. I do have a water softer but it jus started leaking from the head recently so I picked up a refurbished one. B4 it started leaking the previous owner never put salt in it so I'm hoping it's been leaching and when I replace it my tds will drop. What's the tds range that's considered ok for dual membrane? Been while so I don't recall. Thanks!

We recommend running them below 300 TDS. There's no real harm in using a dual setup past 300 TDS, but you'll start to burn through your DI resin pretty quick.
