Okay, I'm stumped. I've read all the other "No Flow" posts I could find, but nothing helped.
I'm running a Hayward SP3400VSP EcoStar Variable-Speed Pool Pump @ 3459 rpm seven hours daily.
My filter cartridge is clean, as are the skimmer basket and pump basket.
I'm also running a Polaris Vac-Sweep 360 Pressure Side Pool Cleaner.
My Aquarite unit is maybe 6 years old and I replaced the original Hayward T-15 cell with a Chlorinator Pro CP-15 cell last year.
The cell was cleaned in June and I can see water flowing through it.
Last nut not least, I installed a new flow switch two hours ago, making sure the arrow is pointing in the right direction, yet the No Flow light is still on all the time.
Here's what it looks like:
I've read that there needs to be 12" of pipe minimum between the Flow Switch and the Cell, but this was "professionally" installed by the store that sold me the Aquarite. I'm open to suggestions here, but can honestly say I'm getting tired of replacing failed components, not to mention having to buy chlorine because my SWG isn't working.
