uPVC 110mm Inspection Tee, 4 Inch, PN12 Drainage Grade

uPVC 110mm Inspection Tee

The uPVC 4 Inch Inspection Tee serves as a critical access point within gravity-fed drainage and sewerage systems. Manufactured from high-grade unplasticized polyvinyl chloride, this fitting ensures long-term structural integrity for underground and surface-mounted waste networks. It provides a secure, leak-proof junction while allowing maintenance crews to perform rodding and clearing operations without dismantling the pipeline.

Built for the Job

Site supervisors and plumbers utilize this specific junction at strategic intervals in main sewer lines or at the base of vertical soil stacks. The primary function involves providing a localized entry for mechanical cleaning tools. Its robust wall thickness resists soil pressure and shifting ground conditions, making it suitable for both residential and commercial infrastructure. The internal bore remains smooth to prevent the accumulation of solids, which reduces the frequency of maintenance calls. This component adheres to standard plumbing codes requiring accessible cleanouts at every change in direction or specific length of horizontal run.

• Installation in main 110mm sewer lines for rodding access.

• Use in vertical soil stacks for high-rise drainage venting.

• Application in commercial kitchen waste disposal lines.
