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 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
Is it OK to replace a 1 HP pool pump with a 1.5 HP?
Yes, you can replace a 1 HP pump with a 1.5 HP pump, provided the exterior dimensions are the same. However, be cautious about the impeller; while it will fit, it won't pump more water since both motors turn at the same RPM.
