My swimming pool sand filter is 30 years old. Parts no longer available.
The valve has begun to leak from a "spider" gasket - basically an 8 inch "O"
ring and a "1 inch "O" ring connected by 3 radials [which separate
rinse/filter/backwash chambers]. The gasket must allow the valve body to
rotate to the three positions so I doubt anything as simple as silicone
caulk would work.
No comparable part available AFAIK.
Replacing the sand filter would not only be pricey, but labor intensive.
Does any one have experience making [or piecing together] such a gasket? Or
a link that might help?
Thanks for any wisdom.

The problem is, even if you patch something together the rest of the
valve and the filter tank are still 30 years old. Ripe for Murphy
rearing his ugly head and causing a crack in the obsolete valve a
month down the road. I'd reconsider replacing the whole thing and
buying a spare set of gaskets for it.

I see a lot of 6 radial spider gaskets for current filters and wonder
if they're close enough to modify.
