Sand in my Pool?

[aylad]

That's the same setup I have.

Generally, cracked laterals are the reason for the sand blowing into the pool. However, mine does this occasionally when the spider gasket on the multiport needs to be changed. I can't explain why it happens, but it does happen almost every year....I'll get a very short burst of zeo through my returns when turning the pump on--no more than 3-5 seconds, then the zeo stops blowing into the pool. However, if you're not diligent about vac'ing it all up, it can create quite a pile after awhile. Yesterday I replaced the spider gasket, and since then, no more zeo in the pool. It's worth a shot--the gasket was $15.50, and a LOT easier to change out than emptying all that sand to check the laterals!!

I will try that step first in hope of clearing up the issues.

Thank you
