I am replacing the sand in my sand filter as sand from the filter is "leaking" back into my in-ground fiberglass pool. I wiil replace the laterals as I am told a broken or split lateral is the only way the "sand leak" could occur. While this explanation for my problem does make sense to me I am always fearful when I hear words like "only."
Is there anything else that could cause the "sand leak" that I should also replace to ensure my problem is solved?
