Anyone with a swimming pool knows the importance of regular maintenance, especially regarding the pool filter. Cleaning the filter regularly keeps water free of debris, which can build up and affect a pool’s circulation. Maintaining the pool’s chemistry to prevent microbes from growing also depends on pool filter cleaning, which ensures pool water remains healthy for swimmers. But when is the best time to clean a pool filter?
Basics of Pool Filter Cleaning
How often cleaning is necessary depends on the type of filter. Sand pool filters require more frequent attention, with cleaning needed at least every other week during the swimming season. DE filter cleaning should happen every month or two. Cartridge pool filters can manage a cleaning once every three months, though this should be done monthly with more frequent pool use.
During the offseason, filter cleaning is still needed, though the frequency is less. Oversized pool filter designs often need to be cleaned at least once every three months, while undersized designs may require cleaning more than once a month. Regardless, if water quality changes noticeably, it’s likely time to consider cleaning the pool filter.
Regardless of the type, a few simple tips for filter cleaning include:
- Using a power washer will reduce a pool filter’s lifespan as it wears out the filtering materials, so cleaning with one isn’t the best idea.
- Though a used filter may appear dirty after cleaning, it should still function properly.
- For cartridge filters, soaking the cartridge in a pool cleaning solution at least once annually will remove buildup and extend the filter’s life.
A working pressure gauge for the pool filter can more easily ascertain cleaning times. However, it’s essential to bleed air from the pressure gauge first to calibrate the device after cleaning. Generally, lower pressures indicate an excellent flow of water in the pool. Filter cleaning should occur once pressure rises by 10 psi above this standardized level, indicating debris is likely caught in the filter and needs to be removed.
Pool Filter Replacement
Sometimes, pool filter cleaning is insufficient to keep the water clear and hygienic so replacement may be needed. However, this depends on how regularly filter cleaning and other maintenance are done. It can last longer if more excellent care is taken with maintaining and cleaning the pool filter. Regardless, pool filter replacement should depend on filter performance.
Typically, sand in pool filters requires replacing once every three to five years, though the filters can last up to ten years. Though cartridge filters can also last that long, cartridges should be replaced every two to three years. With DE filters, five to eight years is the norm. However, replacement depends on factors like pool size, how often the pool is used, and the chemicals used to treat the water.
