First all just like to say thank you, this site has brought my pool back from the dead.
My new issue is that sand is making its way back into the pool. I would vacuum and the next day there would be a slight dusting of sand on the bottom. There isn't a huge amount of sand, I would say roughly 1 - 2 hand fulls spread across the pool. I have already took the sand out of the filter once and replace the collector hub, and there wasn't anything wrong with the laterals. Then two days ago I decided that I would check them again and just 1 lateral had a slight crack at the base no bigger than this ____ . So I just wanted to keep filtering so I used some PVC glue and a q Tip and filled the tiny seam and replaced it back on the hub. So other than just replacing the laterals which from looking at them I wouldn't think they would need to be, is it possible that the wrong sand was used? Is there anyway to tell what sand was used? The filter calls for #20 Silica Sand .40 - .55mm. Or is there something that I am over looking?
Also I have been looking at prices for individual laterals, but is there any where to buy like an 8 pack in bulk or something?
