The ZODIAC 21181-250-000 is a 2.5-inch pipe extension designed for use in pool and spa plumbing systems. This fitting extends existing pipe runs where additional length is needed to connect equipment, adjust for clearance, or complete a plumbing layout. It is a direct-fit component intended for installation by pool service professionals and licensed plumbers working on residential or light commercial aquatic systems.
This pipe extension is suited for pool and spa equipment installations where a 2.5-inch pipe connection is required. Typical applications include extending suction or return lines, bridging equipment connections, and adapting plumbing runs during equipment replacement or system upgrades. It is appropriate for use in both new construction and retrofit plumbing projects.
Designed as an OEM-style replacement extension fitting for 2.5-inch pool and spa plumbing systems.
Installation should be performed by a qualified pool service technician or licensed plumber. Shut off all pumps and depressurize the system before beginning any plumbing work. Use appropriate solvent cement rated for PVC pool plumbing if bonding is required, and allow full cure time before returning the system to service. Follow local plumbing codes for pool and spa installations.
