After many years of loyal service my Doughboy Silica 2 Sand filter has started to leak right around the spider gasket. I really would like to repair this filter and possibly rebuild the valve assembly. My problem is I can not find parts for this filter anywhere. Does anyone know of a supplier who sells parts for this filter? I have found an after market company called SSC (poolgasket.com) but they are very limited on what they sell. Could some please help me get in the right direction? Thank You.
