I beleive I have a kinetico GX with an air bladder tank that is only outputing 1-2 glasses per day- it is 10 years old. I have recently replaced the 2 pre and post filters. I have recharged the bladder tanks to 7.5 psi. I run on well water with a kinetico softener.
Is there something else that could be causing low output? What should I check/
