I'm preparing for the inevitable failure of the cell on my Aquapure 1400. Are there any better alternatives out there if I decide to go with a different system? My frustrations with the Aquapure center around the repeated failure of the flow sensor. I think I've gone through 3 of them in the last 4 years. Would it be cost effective to replace the whole system (are there any better out there)? Is it a major project to switch to another manufacturer?
