Getting sand in pool.  Everyone told me it was probably a broken lateral.  Flushed all the sand from the filter, checked the laterals and all were secure and in great condition.  Any other suggestions before I add new sand and put everything back together?

If laterals are not the issue, the other common problems are a cracked standpipe or a bad spider gasket in the multiport valve. What is the make and model of the filter?

I replaced the entire valve assembly in 2020.  I notice that there is sand coming out of the discharge back into the pool after I backwash and then switch to filter, probably last 10 to 15 seconds, then clears up and is fine afterwards.  Someone told me to try running in the rinse cycle for a few minutes after backwashing and then switch to filter, helps but still seeing sand.
