As a result, you will have to add chemicals to the pool to rebalance more often than for a cartridge filter. Using a sand filter means that you will likely need to replace some water in your pool after backwashing the filter. While many pool owners backwash their filters weekly as part of routine maintenance, you should backwash anytime the gauge reads 5 PSI above the original start-up pressure or when the pressure coming from the return is weak. This will make it difficult to do a good backwash and may result in quick plugging of the filter or breakage of the laterals. You should backwash the filter once every 2 weeks at a minimum or you can cause the sand to become compacted. Most sand filters have a pressure gauge on the outside of the filter, which will help determine when it’s time to clean the filter. They only filter particles as fine as 20 microns.
They’re low maintenance as you don’t have to take them apart for cleaning, but the sand needs to be replaced every 5 to 7 years.
