What Is a WOW Pump?

WOW (Water on Water) pumps are dedicated hydrotherapy jet pumps that use water pressure rather than air injection to power massage jets. The 12 o’clock discharge position refers to the orientation of the pump outlet relative to the motor, which must match your spa’s plumbing layout for proper installation.

Installation

This is a complete pump assembly for direct replacement. The 12 o’clock (top) discharge orientation is specific to certain spa cabinet configurations. Verify your existing pump’s discharge position matches before ordering. Professional installation is recommended.

Common Symptoms & When to Replace

Signs of a failing WOW pump include weak or inconsistent jet pressure, abnormal noise during operation, the pump not starting or tripping the breaker, and visible leaks from the pump housing or shaft seal area.
