FAQ
Our expert staff answers customer's most asked questions.
How does Shasta Pure compare to traditional chlorine systems?
Shasta Pure offers several advantages over traditional chlorine systems:
- No harsh chemicals, providing a more natural swimming experience
- Improved water clarity and softness
- Reduced environmental impact with healthy backwash water
- Lower maintenance requirements
- Increased comfort for sensitive swimmers
How many HP pumps do I need for a pool?
The horsepower (HP) of your pool pump should match your pool size and flow rate, which usually ranges from 40 GPM to 80 GPM. Generally, pool pumps range from 0.75 HP to 3 HP. Opting for a higher GPM flow rate can help reduce wear and tear on your pool equipment.
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.
