I just completed installing my new BRS 150gpd RO/DI system. I had some doubts about where to put the DI filter, the BRS instructions refer to the RO system but nothing really babout the DI canister except to say the TDS coming out should always be 0. I concluded based on this statement that the DI canister should be last. But then why the longer tubing on the RO output and the short one on the DI? And the input of the DI is opposite the output of the RO filter.
I swapped the tubing so i hve longer reach with the final RO water, and It appears that I could unscrew the canister bracket and get othe output of the RO to be adjacent the input of the DI. But, before I start doing that, I thought I'd check here to make sure I set things up correctly. I'm currently doing the 1hr flush before using and the TDS going into the DI canister are fluctuating a bit but around 8, with the output at 0.
Attached is a picture - just want to get a sanity check. Thanks in advance for the feedback.
RO on the right, feeding the DI on the left. Output tube of the DI canister is the good water ;-) black tube from the RO canister is this bad water.
