Specifically designed for Hot Spring, Caldera, and Tiger River spas, this energy-efficient 39-watt pump ensures your water remains clean and heated with minimal power consumption.

🚩 PRO TIP

When replacing your old SilentFlo 5000, ensure you bleed the air from the plumbing by slightly loosening the discharge union until water flows steadily. This prevents air locks and protects the pump's water-lubricated bearings from dry-run damage.
