Tulsa Water eats RO membranes


Premium Member
I have been hearing stories 3rd hand about RO membranes not lasting long in Tulsa this spring. And now I have experienced it. I installed a new RO membrane and replaced all 4 cannisters in my Spectapure RO/DI unit two weeks ago, and already am flashing red on the meter.

I will attempt to measure chlorine and TDS later today.

Evidently, the City of Tulsa is having difficulty maintaining consistent levels of chlorine due to this spring's heavy rains. Is there a way to minimize the effect of fluctuating chlorine content? Can additional carbon filters be installed upstream of the RO to protect it?
