When I had my pool opened this year, the bolt holding the tank clamp was stripped and broke off. Given it was integrated in the tank clamp, it would have required a ~$150 replacement tank clamp. The filter is likely nearly 40 years old; so along with a number of other reasons I opted to replace it. Is there any value in the other parts to this (e.g., the filter grids are in good shape...no idea how old they are, but they look great)? Just wondering if I should haul it off to the junkyard or if there is any value there to help offset the cost of my new pump. I imagine there is not much value as my pool guy was not eager to take it, but thought I would at least ask before I carted it off.
On a related note, any use for old DE? I converted to a sand filter, and I've read about people adding DE to their sand filter, but my water doesn't look any less sparkling with the sand filter than it did with the old DE filter. I hate to toss it, but does it go bad if for some reason I wanted/needed to add DE to my sand down the road?
