I'd like a bit of help with diagnosis.
The pool is green at the moment which I'm going to treat but let's ignore that for the moment.
The filter has been in service just shy of 13 months.
Sand at the exit of the backwash plumbing (it's hard plumbed to the front yard) has been building.
Because of the great hoorah death of the old filter, I ignored it. It's probably been going on for months.
However, there's sand in the backwash plumbing right off the valve, so it's definitely from the new filter.
My thinking is it could be the wagon wheel gasket (but that looks perfectly fine) or damage / cracks to the valve (none seen)
Or it could be busted spraybars / hub.
I did install the spraybar setup properly, sinking it in water and adding sand after it was correctly placed.
The valve looks fine. I've only had it off once before to lube the gasket and everything is intact, the spring is solid, the gasket is perfectly intact.
What else could it be?
Any quick tips on draining sand out for what I think will be inevitable?
