Independent Supplier & Replacement Part Notice
We are an independent parts supplier and are not affiliated with, sponsored by, or endorsed by Watkins, Hot Spring, Caldera, Tiger River, or Solana. These names and their part numbers are used only to identify compatibility.
We offer replacement parts as alternatives to spa-branded parts. When this listing identifies a part as the same original-manufacturer replacement, it is supplied under the component manufacturer’s branding and part number, which may differ from the Watkins or spa-brand label and number. Other compatible alternatives are identified in the individual product listing. Please review the listed specifications, fitment details, and any installation differences before ordering.
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)
