If using sand and gravel filters, they should be inspected after the irrigation season. If the filter sand is caked or has a lot of dirt, it should be thoroughly cleaned, and new sand should be added if necessary. When using laminated filtration, the filter should also be cleaned in a timely manner. In winter, the water in the filter should be emptied, otherwise the equipment may freeze and crack when it freezes.

The filter should be installed with markings in the direction of water flow. When using a screen filter, the filter cover should be removed for flushing after each filling, and damaged components should be replaced. At the end of the irrigation season, filter elements should be promptly removed and thoroughly cleaned, and all components should be maintained.
