sand returning in pool

[ksturge]

Can I ask some more questions about sand in the pool? I am having this very same problem. I know it isn't normal - or even coming from a sandbox. My question is - how do I proceed? I don't even know what a lateral is? How would I know if one is cracked? Please help - you guys seem to know everything there is about pools.

A lateral is in the filter it self it looks like a fan. In order to get to it you will need to dump the filter. It is not easy to change the laterals AT ALL. Good luck!!!!!

I'd like to know what part of changing laterals is hard? Maybe the turning over of the heavy filter tank to scoop the sand out???
Best way to get the sand out is remove the multi port valve, turn tank on it's side, use a hose to wash it out -basically letting the water do the work, once clean, reach in and unscrew the laterals, inspect and replace as necessary - I would also inspect the standpipe and fittings, sometimes those are the culprits.

Could this problem be also caused when the pump's GPM flow exceeds the sand filter's GPM flow rating and forcing sand out of the filter??
