Does pool sand wear out and need to be changed?

Yes it does. I've replaced my sand twice in 12 years. But I know others who have not. Depends on the amount of debri it has to remove and what type. I have too many nearby trees. I knew my sand was finished when the back pressure got so high it blew out the skimmer basket when it turned off. Replacing the sand takes a couple of hours. Good luck.

Sand needs to be replaced every three to five years. Proper backwashing and treatment with a sand revitalizer will keep your filter working efficiently throughout the sand's useful lifecycle.
