I am a second year inground pool owner.
I am seeing sediment, sand I believe since we have a Heyward sand filter, blowing right back in the pools when I vacuum.
This issue did not exist last year.
I have backwashed and rinsed multiple times and the sediment still flows into the pool.
The filter is not new, however I do not know it's exact age.
Your videos and explanations of how a sand filter works is fantastic.
Could this be an issue with the laterals?
The chemical levels are all within the required ranges.
I looked for this topic and did not find it, but my apologies if this is a redundant topic.
