View Full Version : TDS rising

03/23/2016, 02:02 PM

I purchased a Mighty Mite system in August of 2015, put probably less than 100 gallons through it so far (RODI, so likely 400-500 gallons total through the system) and am already measuring 15-25 tds coming out the good end. Water from the tap is roughly 200tds.

three questions:

1.) is it normal for TDS to start to creep this soon?
2.) Which filters are my most likely culprits in the system that I need to replace?
3.) I noticed that you plumbed the carbon block first and the sediment filter second. Is this normal? Should that be the other way around? Could that be leading to the fall in performance so quick?
