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 part is a Replacement Watkins Water Check Valve that is 3/4"Barb x 3/4" Barb.. This 3/4" water check valve is installed in the inlet side of the circulation pumps plumbing to prevent the back flow of water through the circulation pump once the jet pump is activated. All water check valves have arrows stamped on the outside to indicate the direction of flow which should be pointer towards the circulation pump.
Troubling Shooting: The symptoms of a non-operative check valve are; * Water Leak - If water is leaking from around the check valve, it should be replaced. * Rattling - A rattling check valve indicates that water is not being allowed to flow properly past/ through the check valve. * Verify the check valve is installed with the flow in the correct direction. * Heater High-Limit Tripping - Poor water flow through the check valve could lead to heater high-limit tripping. Ensure the check valve is not block by debris and operating properly. * Surging jet pump (on spas equipped with a flow switch)
