...If you want your pentair salt cell covered under warranty. A few weeks ago I came back from vacation and found a little bit of algae and a quick test showed no FC in the pool. SLAMed the pool and noticed that the red low salt indicator light was on. I tested the salt level and it was fine. I took the cell out and cleaned it. When I put it back in it showed the salt level was at 4900 ppm. The next day it showed 2350 ppm. It's only 2 years old on a new pool and I had the multiple pentair product 3 year warranty. I called warranty and the guy ran me through a few questions. The last one he asked is if I have phosphates. He said if he sends the warranty company out and even if the cell is dead and there are phosphates in the pool this will turn into a $200 service call I'm on the hook for instead of a warranty claim. So my question to you experts is do I spend countless dollars on jugs of phosphate remover to get pentair to send me a new cell or just cut my losses and buy a new cell or convert to Clorox?
