I have a 2.5yr old Pentair IC40 SWG with plenty of life left according to the run-time light readout. It has work flawlessly the last 2 summers. Over the past few weeks it seems to be 50/50 on whether the flow light is Red or Green... and as a result I'm not making enough chlorine based on my run-time settings. What are the likely culprits?
I'm thinking it's unlikely to be an obstruction, as it comes and goes. The flow is not actually low... as I've backwashed the filter several times, changed the pump speeds, and the flow rate is much higher than needed to produce (based on past seasons and observing the jets.
Thoughts? Planning on removing the cell to inspect next weekend when I get a chance.
Thank You.
