    Pentair / Compool Diverter Valve Scrapping - Scuffing - Abrasion

    Required Intellichlor IC40 Entry & Exit Pipes

    Hello All, I’m replacing my 20 year old equipment and have settled on a complete Pentair setup after a lot of reading here at TFP. I really liked the Autopilot system and it's great features, but in the end I decided the simplicity of a single controller works best for my needs (I'm going...
