Hayward Goldline Flow Switch w/ 2" Unions | P-KIT

The Hayward Goldline Flow Switch (P-KIT) is a genuine OEM pool and spa flow sensor designed to monitor water circulation in your pool’s plumbing system. Installed in line with your pump and filtration equipment, this flow switch ensures that adequate flow exists before allowing connected equipment—such as heaters, chlorinators, or automation systems—to activate.

This kit includes 2" union fittings for easy installation and leak-resistant connections. When the water flow drops below safe levels (due to blocked filters, pump issues, airlocks, or suction problems), the flow switch signals control systems to prevent equipment operation—protecting heaters and other components from damage caused by inadequate circulation.
