which Hayward Filter do i have?

[Guest]

My sand filter circumference is 74" and I need to know if it is an S200 or 240 to purchase new springs, it is a leaky mess.

Thanks!

Assuming that is the circumference of the filter shell and not the lip that bolts it together, then I would guess 74/pi=23.55, so I would think it is the S240.

I meant to order o-ring replacement. I actually measured the lip outside the bolts. I will re-measure the tank itself at its widest.

I also could not find a good set of dimensions to tell the difference between the 2.
