Do you need to drain an in-ground pool every few years recycle the water?

It is not necessary to drain and recycle the water in an in-ground pool every few years. With proper maintenance, pool water can last indefinitely. Regular chemical treatment, cleaning, and filtration can keep the water clean and safe for swimming. Draining and refilling a pool can be time-consuming and costly, and it can potentially damage the pool's structure and liner. Unless there are specific issues or concerns with the water quality, it's generally not necessary to drain and refill an in-ground pool.
