How the Gunite Venturi Tee Nozzle Extension Works
Waterway Gunite Venturi Tee systems are used in pool and spa hydrotherapy plumbing to direct pressurized water through compatible jet assemblies. The nozzle extension is part of the internal plumbing configuration used to position the nozzle within the venturi tee installation.
The retaining ring helps secure the extension component in its intended position. Proper installation and nozzle alignment are important for maintaining the designed flow characteristics of the spa jet system.
