Which method is recommended for cleaning a sand or DE filter?

Backwashing is the recommended method for cleaning a sand or DE (diatomaceous earth) filter because it effectively removes accumulated debris and contaminants trapped within the filter media. During backwashing, the flow of water is reversed, forcing dirt and particulate matter out of the filter and into the waste line. This process not only clears out the filter but also helps to maintain the filter's efficiency and prolong its lifespan by reducing pressure buildup and optimizing water flow through the system.

Regular backwashing is essential to ensure that the filter operates efficiently, as it removes clogs and allows for better water clarity and sanitation in the pool. Additionally, after backwashing a DE filter, it is recommended to recharge it with fresh DE powder to restore its filtering capability, highlighting the importance of not only cleaning the filter but also maintaining its operational integrity.
