Elizzy Posted June 30, 2011 Share Posted June 30, 2011 Hey there!! Have a quick question regarding a recent TDS reading on my RODI water. Normally it's 0 or 1, but yesterday it was 21. Does this mean I should change the membrane? (I do have a spare ready.) The unit has been live since February. Also, I thought Mark posted something about TDS going up in Texas water due to the draught, but I couldn't find it. Is 21 water still ok to use? Much thanks!! -E Quote Link to comment Share on other sites More sharing options...
Mindflux Posted June 30, 2011 Share Posted June 30, 2011 I'd check your DI resin before you look at your membrane. Do you have a TDS meter that can read the in and out streams from the unit? Quote Link to comment Share on other sites More sharing options...
Elizzy Posted June 30, 2011 Author Share Posted June 30, 2011 I may have misspoke when I said membrane - I just bought an extra filter (the top horizontal part - if that's the membrane) of a 3 part diagonal system. The tds meter can read in and out. Normally in is 175 - I haven't checked it yet, I will and report back. Quote Link to comment Share on other sites More sharing options...
+dapettit Posted June 30, 2011 Share Posted June 30, 2011 I see a change of di resin and filters in your future. Dave- Quote Link to comment Share on other sites More sharing options...
wa1tx Posted June 30, 2011 Share Posted June 30, 2011 I would start with the DI resin. Brs has it relatively cheap. Quote Link to comment Share on other sites More sharing options...
Elizzy Posted July 2, 2011 Author Share Posted July 2, 2011 (LOL Dave) Yep, 170 current reading of water going in. Is the 20 tds water ok to use? If not, I'll just dump my jugs out...on the lawn. Thanks!!! Quote Link to comment Share on other sites More sharing options...

Elizzy Posted July 4, 2011 Author Share Posted July 4, 2011 Well it turns out I had bought resin and micron filters, not the membrane - lol! Replaced all, 0 TDS Quote Link to comment Share on other sites More sharing options...
