The sand in a pool sand filter is specially built to trap particles in the 20 – 100 micron range. As a sand filter collects dirt, its efficiency increases, trapping more dirt. When the pressure gauge shows a reading 8 – 10 lbs. over the clean, start-up reading, it is time to backwash the captured dirt out of the filter.

How often should I change pool filter sand?
When do I need to replace my sand? On average, sand should be replaced every 18-24 Months. This may be longer if the pool stays clear, or shorter, if the filter runs all the time. The jagged edges of the sand wear down and become smooth as the sand ages.
