How frequently should swimming pools generally be completely drained for maintenance?

The appropriate frequency for completely draining a swimming pool for maintenance can depend on various factors, including the type of pool, local climate, and pool usage. Generally, most sources suggest that draining a pool every 3 to 5 years is ideal for maintenance purposes.

During this time frame, pooling water can accumulate debris, minerals, and contaminants that regular cleaning may not fully remove. Draining the pool allows for a thorough cleaning of the surfaces and equipment, helps prevent scaling and staining, and provides an opportunity to inspect the pool structure for any damages or necessary repairs. Not draining the pool could lead to long-term maintenance issues that are more costly to rectify.

Maintaining a routine of every 3 to 5 years strikes a balance between thorough upkeep without being excessive. Regularly checking for leaks or other maintenance issues can also inform whether a more immediate drain is necessary, but the established protocol of 3 to 5 years serves as a best practice guideline for regular pool maintenance.
