Usually, all types of sand filters available in the market use the same basic mechanism. When set to “Filter,” water flows from the pool via the filter and goes back into the pool. The sand in the filter works to block debris, oil, and dirt. A standard sand filter consists of 6 different settings, including filter, backwash, rinse, circulate, closed, and waste.
When the vacuum is performed, a certain amount of dirt gets into the sand. As a result, the sand becomes clogged with contaminants. If you don’t notice it, the filter’s ability is reduced and fails to maintain the charity of the pool water. Therefore, you need to perform backwashing to prevent this problem. Backwashing does reverse the flow of water, flush the sand, and also remove the dirty water via the waste line to the ground or drain. In addition to preventing residual blowback into the pool, after finishing backwashing once, you must rinse the filter.
A usual rule of thumb is once every 14 days. The right time to backwash is immediately after vacuuming your pool. You can also predict the backwashing time after checking the pressure gauge of the sand filter. When you see the KPA pressure on the gauge is north of 80 KPA, it’s the right time to backwash. Usually, normal operating pressures are between 50 and 75 KPA.
