Nigel July 3, 2018 at 1:50 pm Hi Cindy. It’s not uncommon to backwash a sand filter once a week. More depending on how much use the pool is getting and how much debris is getting in the pool. There are filter cleaners available to clean sand: https://support.aqua-tech.ca/store/index.php/pool-chemicals/miscellaneous-cleansers-testing-supplies-and-more/filter-brite-chemically-clean-your-sand-filter-every-year-sale.html On average it’s not a bad practice to replace the sand every 4-5 years depending on how dirty it has gotten.
