Hi......Just joined TFP. Not sure if I should start a new post or not since my issue is very similar to this. I have sand in my backwash every time. A couple of years ago I emptied the sand and checked the laterals and everything looked okay but we continue to lose sand. Now I'm getting ready to check the sand level again. Any ideas on what would cause us to lose sand in the backwash if the laterals are okay?
