Need help figuring out what pool filter I have

Hello BigJohnW - It looks like you have an old Pac-Fab Superflow 100 Stainless Steel Sand Filter. Were you looking for any particular parts?

Yes I’m looking for a o ring

The part number for the tank o-ring is O-337. This is the 16" o-ring for the top of the Pac-Fab Superflow PF-100 filter. These are in stock and ready to ship.

Thanks also any ideas on my back flow

I’m missing the bottom o ring and there’s a chip on the to one

We have a universal rebuild kit for the Pac-Fab valves. The part number is GOKIT23.

Thanks I tried it and it did help but did not fix the problem 100% I think I need a whole new backwash push pull valve. What one will fit my  old Pac-Fab Superflow 100 Stainless Steel Sand Filter

What is the center to center measurement between the intake and discharge ports on the filter? This would be a measurement from the center of one port to the center of the opposite.

It’s 8 inches

The push-pull valve we have for 8" is part number 263052. We are not 100% it will work but it’s the best shot we have. If you order it from us and it doesn’t match up, it can be returned for a full credit.
