Maintaining a pool sand filter is relatively straightforward. Regular backwashing helps keep your filter functioning correctly and can extend its lifespan. Backwashing means running the water in the opposite direction, causing the dirt and debris that were being filtered to be cleared out of the filter media and sent back out of the drain.
Most filters should be backwashed once every month or after heavy use. Before you start a backwash, you need to turn off the pump and clean out the skimmer basket.
If you backwash your sand filter too frequently, it may become overly clean and not be able to capture finer particles effectively. This happens because finer particles have a greater opportunity to bounce around and break down when they come into contact with the already-dirty particles present in the filter. As a result, it is important to avoid backwashing too often to ensure that your sand filter functions optimally.
In addition to backwashing, the sand in a pool sand filter needs to be replaced every 7 to 10 years, depending on usage and the state of the water. The sand should be changed all at once, because adding new sand on top of an old layer won’t do a good job of filtering.
Lastly, you must use the correct sand for your filter. Not all sands are appropriate for filtration, so always consult the manufacturer’s instructions for specific recommendations on the sand type.
