I need advice regarding my sand filter. I purchased my home a little over a year ago. The home has an inground pool, around 26k gallons. The existing filter is a Pentair TA60 sand filter. The filter had 2 issues... I can see sand in the pool during last summer, so I'm thinking one of the laterals might be damaged. In addition, there must have been a leak for the previous owner, because he sealed the pressure valve with an epoxy putty of some kind, so that valve is never coming off.
I figure I can either replace the valve head and laterals, and sand while I'm at it, or just buy a replacement, maybe the TA60D. Any thoughts on what would be the best way to go? And also, how difficult is it to repair this thing? Any input would be greatly appreciated. Thanks.
