FAQ
Our expert staff answers customer's most asked questions.
Can I pick up my order at any time?
Orders can be picked up during our operational hours. You'll receive an email when your order is ready for pickup.
How often should I drain my pool?
It is recommended to drain your pool every three years to eliminate accumulated chemicals and dust. This varies depending on many environmental conditions like fill water and the type of chlorination you are using. Our advice is to have your water tested before and after by a local pool professional.
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.
