Use the reducer only in indoor drainage systems with compatible pipe materials and diameters. Follow local plumbing codes for sealing and support, and avoid exposing the fitting to temperatures or chemicals outside its intended use. Periodically inspect joints after installation to ensure continued watertight performance.
