Product Overview
110mm Universal Rainwater Adaptor designed to connect vertical rainwater downpipes into 110mm underground drainage, forming a watertight joint that channels roof water safely into the system.
Manufactured from durable uPVC to BS EN 1401-1, it provides a straightforward solution for linking gutter outlets and rainwater pipes to underground runs without leakage.
The adaptor accepts a variety of common downpipe sizes, ensuring compatibility with most domestic and light commercial rainwater systems. Once fitted, it creates a sealed connection, preventing water loss at the junction and ensuring roof runoff is directed efficiently into foul or surface water drains.
By providing a secure transition between above-ground rainwater systems and underground drainage, the adaptor helps protect buildings and paved areas from pooling or uncontrolled surface runoff.
Features & Benefits
- Universal connection: Accepts a range of standard rainwater downpipe sizes.
