FAQ
Our expert staff answers customer's most asked questions.
Are there any specific considerations for saltwater pools?
Yes, saltwater pools require pumps that are compatible with saltwater systems. Look for pumps made from corrosion-resistant materials to ensure longevity and efficiency in saltwater environments.
How does Shasta Pure work?
Shasta Pure uses a combination of oxygen and nanobubbles to purify pool water. This natural process sanitizes the water effectively and provides a clean and safe swimming environment without relying on traditional pool chemicals.
What is better for my pool and my body: Salt Chlorinator or Chlorine Chemicals?
Opting for a salt chlorinator is a superior choice for both your pool and skin. In addition to cost savings on chemicals, it requires minimal maintenance with a 5-7 year replacement cycle on salt cells. Most salt cells have an operating life of 10,000 hours. Proper maintenance will help extend the life cycle of salt cells. Refer to your owner's manual for cleaning instructions and tips on cleaning Pentair salt cells and products that help keep all salt cells cleaner.
