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.

Features dual voltage capability (115V or 230V), operates at temperatures up to 140°F, and handles line pressure to 50 PSI. Ultra-quiet operation combined with compact, lightweight construction under 5 lbs makes installation simple in tight spaces.
Built-in microprocessor protection prevents dry-run damage while high-density ceramic ball bearing and carbon graphite bearing cap ensure reliable long-term operation. Comes complete with 4ft power cord attached and (2) 3/4" outside diameter barbed connections for easy plumbing integration.
