Underground Drainage Pipe – PVC – Outdoor Drainage Systems

Product Overview

The 110mm underground drainage pipe with a single socket is designed for both foul and surface water drainage systems. This pipe comes in a 6m length, making it ideal for longer drainage runs, thereby reducing the number of joints and enhancing overall system efficiency. Made from unplasticised PVC (uPVC) to BS EN 1401-1 standards, it is strong, lightweight, and durable for underground installations. The integrated push-fit socket connects directly to a plain-ended pipe or fitting, simplifying installation and eliminating the need for a separate coupler.
