Every time I vacuum on filter I have to backwash when I'm done. Is this normal? I have completely rebuilt the filter. New sand, multiport, laterals and shaft. Not sure if this is normal or not.

My normal pressure is around 12 and can jump up to over 20. It isnt a whole lot of gunk either. Mostly some sand and dirt. A few small pieces of leaves and some beatles and spiders. Maybe a small toad or two
