    Are you running it on the rinse position before going to filter?

    Is this a new filter, or did you just replace the sand?
    It may be just sediment blowing through and will subside soon.
    If it's older sand, you may have a crack in one of your filter laterals.

    There's also the Rinse position on the valve, which "settles" the sand back down before going back to the Filter mode.
    Filter --> Backwash --> Rinse --> Filter

    my filter is less than a year old ut no real new. the planger pushes down to backwash and pulls up to lock in place to filter. i don't know what you mean by rinse.

    You have a slide valve. There's no rinse setting.

    You most likely have a cracked lateral.
