The PENTAIR 984023 is a packaged set of four Arrowhead valve seats designed for use in pool and spa plumbing systems. Valve seats are the sealing surfaces inside diverter and multiport valves that allow them to hold pressure and direct flow without leakage. Replacing worn or damaged seats restores proper valve function and prevents water bypass. This kit is sold as a set of four seats, making it suitable for full valve rebuilds. Installation is performed by licensed plumbers or experienced pool service technicians working on residential or light commercial aquatic systems.
This seat kit is used during routine valve maintenance or repair on pool and spa plumbing systems where Arrowhead-style valve seats are specified. Typical applications include multiport valve rebuilds and diverter valve overhauls where the seating surfaces have worn, cracked, or lost their seal. The four-pack format supports a complete seat replacement in a single service call without the need to source individual components separately.
Designed as an OEM-style replacement for Arrowhead-style valve seats used in pool and spa plumbing valve assemblies.
Installation is typically performed by a licensed plumber or qualified pool service technician. Shut off all circulation pumps and isolate the valve from system pressure before disassembly. Follow the valve manufacturer's service manual for proper seat seating depth and orientation. Refer to applicable plumbing codes, such as the IPC, for any pressure-side plumbing work.
