Common Questions
Questions to Check Before You Choose
Can I use a clean-water pump for pool water?
Only when the water, treatment chemicals, temperature and debris are within the selected model’s limits. Describe the pool water before choosing, especially for saltwater or heated pools.
Will a low-level pump empty the pool completely?
It can help remove the shallow final layer, within its starting and operating conditions. The listed clean-water models still have a residual water level; they do not leave every pool completely dry.
