Thanks in advance for everyone's help. Completed a brand new inground pool / spa build just under a year ago. Been following the TFP method and everything chemical related has been working great as I've been maintaining everything myself.
I have all Pentair equipment and about 6 months in, I've had to replace the flow switch on my IC40 under warranty (faulty temp readings).
Strange thing is the last couple months I've had to keep increasing my pump speed so I dont get a "low flow" light on the IC40. System was working great and producing chlorine at about 1600rpms for a few months, now I've had to keep increasing the speed and now need to be at over 2100rpm so the light wont come on. I removed the IC40 yesterday and it is clean with no scaling or obstructions that would prevent the flow switch from working correctly.
On a side note, yesterday I noticed that my spa spillover is not spilling over like it used to with the main pump running and circulating the water from the spa to the pool. All the valves have not been moved and are in the same position they have always been.
Main DE filter was cleaned and recharged about 3 months ago and pressure is normal. Use a robot for cleaning and hairnets in the skimmer so system should be pretty clean and debris free. All pump and skimmer baskets are crystal clean.
I'm stumped. Could these 2 issues be related? Any idea what the problem could be?
