I am having some filtering issues, and have a quick question.
Is it possible to have broken laterals *and* not also have sand being returned into the pool as a result?
I know the general consensus is that you don't really ever need to replace your sand in your sand filter. A yearly deep cleaning or two should be all you need. I'm at a loss though and wondering if I need to change my sand, because I'm still having return issues even after a deep cleaning. Doing a shock cycle also never really raises my filter pressure enough to the point where I would expect to perform a backwash, which leads me to believe it's not really filtering well (which is evident from the color of my pool - chemicals and balance are fine, water is clear but constant green).
If I had damaged laterals or filter issue, wouldn't I also get sand in my pool from those broken laterals? Because I don't have sand in the pool at all, so just want to confirm that it's not worth the effort of wet vac'ing all the sand out of my filter to inspect the laterals.
