Frequently Asked Questions
Q: What does "self-priming" mean?
A: Self-priming pumps pull water from below without manual priming. Installed outside the pond (dry), they draw water through suction for safer, easier maintenance.
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 GPH models handle taller waterfalls.
Q: What is maximum suction lift?
A: Vertical distance the pump can draw water upward from pond to pump. BT1466C/BT1373C: 4' | BT1292C/BT34105C/BT1120C: 7-9'.
Q: Can I use flexible pipe?
A: Yes, quick-connect fittings accommodate 2", 2½", and 3" rigid or flexible pipe. Use appropriately sized pipe for optimal flow.
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.
