Reducing pipe tee Certus 110/75 – PVC drainage fitting 110 mm to 75 mm

Reducing pipe tee Certus 110/75 is a PVC drainage fitting designed to join a 110 mm main pipe with a 75 mm branch. The fitting provides a smooth, secure transition between different diameters in wastewater and stormwater systems, supporting direction change and network branching in both underground and above-ground installations. Constructed from rigid PVC, the tee delivers consistent inner surface geometry to maintain flow and reduce the risk of blockages.

Advantages

The Certus reducing tee offers reliable sealing between pipes, straightforward installation with compatible solvent-weld or push-fit connections, and dimensional stability under typical drainage loads. Its smooth internal profile minimizes flow resistance and sediment accumulation. The material resists corrosion and many common chemicals encountered in household and commercial wastewater, contributing to long service life when installed according to standards.

Suitable for

• Residential drainage networks for wastewater and roof runoff
• Commercial and light industrial stormwater and sewer branches
• Underground and above-ground PVC drainage systems requiring diameter transition

Key specifications

• Material: rigid PVC suitable for drainage applications
• Main pipe diameter: 110 mm
• Branch pipe diameter: 75 mm
• Type: reducing tee for lateral connection
• Application: wastewater and stormwater drainage
• Installation: compatible with standard drainage joining methods (solvent-weld or push-fit where applicable)

How to use

Select a suitable position in the drainage run where the 75 mm branch is required. Prepare pipe ends by cutting square and cleaning contact surfaces. Fit the 110 mm main pipe and the 75 mm branch into the corresponding sockets following the chosen joining method and manufacturer instructions. Ensure correct alignment and slope to maintain gravity flow, and verify seals after installation. Backfill and support underground runs as recommended to avoid point loads on the fitting.

Usage recommendations

Confirm compatibility with the rest of your PVC system components and use appropriate joining materials and tools. Observe local building codes and standards for drainage installations, maintain recommended slopes for gravity drainage, and avoid exposure to prolonged UV without protective measures.
