Changed RODI filters/ now TDS IS UP

[bj274]

I changed out all my filters and membrane because it’s been running a couple of years. I had zero TDS in and out prior to changing and now it’s 4 in and 2 out?
Any ideas on why?
5 stage BRS 75gpd RODI

Is the DI resin packed tight?

How tight we talking? I pushed on it with my fingers and had to take a little out for the top to go on good, but did not get all of the new bag into it

I never get the entire bag to fit either. However if the canister isn't packed tight enough you'll get the mentioned results

It has gone down to 2 in and 1 out now, but prior it was 0 in as well ‍

I would take the DI canister, and smack it on the counter a couple times at the bottom so the DI settles out, similar to how you smack a pan of cake batter on the counter to get all the air bubbles out. If you see the level go down, add, repeat, then compress it as best you can, then run some water for a little bit and see if you get back to 0 tds
