Reducer T-Connector Certus C167110S — 110 mm to 75 mm PVC sewer fitting

Certus reducer T-connector C167110S is a PVC sewer fitting designed to create a compact junction between a 110 mm main sewer pipe and a 75 mm branch. Intended for drainage and wastewater systems, the fitting provides a sealed connection that maintains flow direction while adapting pipe diameters. Its construction from PVC ensures chemical resistance and compatibility with standard PVC sewer pipes used in both underground and internal drainage installations.

Advantages

The reducer T-connector offers straightforward integration into existing PVC sewer runs, enabling a reliable transition from a larger main pipe to a smaller branch without complex adaptors. Its PVC material provides corrosion and chemical resistance typical for wastewater applications, while the design supports secure sealing to minimise risk of leakage. The compact form factor simplifies installation in confined spaces and helps maintain hydraulic performance across the junction.

Suitable for

• Domestic and commercial wastewater drain lines where a 110 mm main needs a 75 mm branch
• Underground sewer runs and manhole connections requiring a diameter reduction
• Internal building drainage systems such as soil and waste stacks or horizontal branches

Key specifications

• Material: PVC suitable for sewer and drainage use
• Main pipe diameter: 110 mm
• Branch pipe diameter: 75 mm
• Type: reducing T-connector for sewer applications
• Suitable for underground and internal drainage installations

How to use

Prepare the pipe ends by cutting square and deburring both the 110 mm main and 75 mm branch pipes. Ensure mating surfaces are clean and dry, then insert pipes into the connector sockets according to manufacturer guidance for depth. Use appropriate sewer-grade solvent weld or rubber-seal methods compatible with PVC fittings, following local plumbing codes. After assembly, verify alignment and allow any adhesive to cure before testing the system with a water or pressure test to confirm a watertight connection.

Usage recommendations

For long-term performance, install the reducer T-connector in accessible locations when possible to allow inspection and maintenance. Follow local regulations for bedding and backfill when used underground, and choose compatible solvent cement or seal rings rated for PVC sewer systems. Avoid exposure to elevated temperatures and direct UV where prolonged sunlight could degrade PVC properties.
