Description
This genuine Watkins 3/4" Barb x 3/4" Barb Water Check Valve with Connection Kit is designed for compatibility with Hot Springs, Caldera, and Tiger River spa systems. The included connect kit facilitates attachment to existing 1/2" flexible tubing (approximately 3/4" outer diameter) by sliding the flex line into the 3/4" clear connector, then securing with adhesive and clamps.
This 3/4" check valve installs on the circulation pump's inlet plumbing to stop reverse water flow when the jet pump engages. Directional arrows molded onto the valve body indicate proper flow orientation toward the circulation pump for correct installation.
Diagnostic Indicators of Check Valve Failure: * Water Seepage - Moisture around the valve housing requires replacement. * Rattling Sounds - Noise signals restricted water passage through the valve mechanism. * Confirm arrow direction aligns with intended water flow. * Heater High-Limit Activation - Restricted flow may cause heater safety trips; inspect for blockages and proper valve operation. * Jet Pump Pulsing (on models with flow switch equipment)
