Frequently Asked Questions
Q: Why choose 230V over 115V pumps?
A: 230V pumps are more energy-efficient for high-flow applications, drawing less amperage for the same power output. They're ideal for commercial installations and large water features requiring maximum flow rates.
Q: Which model do I need?
A: Consider waterfall height and desired flow. Use 100 GPH per inch of waterfall width. Check performance at your specific head height. Higher models handle taller waterfalls and larger volumes.
Q: Do I need special electrical service for 230V?
A: Yes, 230V pumps require a dedicated 230V circuit. Consult a licensed electrician to ensure proper electrical installation and compliance with local codes.
Q: What is maximum suction lift?
A: Vertical distance the pump can draw water upward from pond to pump. BT12HF: 5' | BT34HF/BT1HF/BT2HF/BT3HF/BT5HF: 8-9'.
Q: How do external pumps compare to submersible?
A: External pumps offer higher flow rates, easier maintenance, better efficiency, and eliminate in-pond electrical concerns. Require dry installation location near pond.
