I don't know the model, that's what is making it so difficult. I've got an alternative arriving today, that I'm going to modify to fit. Fingers crossed it works! Crazy Pentair's suggestion was to buy a new filter at a cost of like $750 vs a $80 part.
The part came. It is IDENTICAL to the part that was broken on mine. The only difference is the length of the laterals, which they both sell new, and my old ones are all in decent condition. No options but buy a new one hey Pentair?
