I have been getting sand in my pool for a couple of years. I was told to and did inspect the Lateral Assembly in my sand filter before I put sand in. It visually appeared fine but I am still getting sand in the pool. Could there be a very small crack somewhere in the lateral assembly in the sand filter? I am thinking about replacing just the lateral assembly w/pipe. Advice?

Yes, we recommend inspecting that lateral assembly. They are known to get damaged and cause sand to get back to the pool. Also, you may want to inspect the spider gasket in the multi-port valve. If as soon as you backwash the sand returns back to the pool then it may also be the spider gasket.
