This standard lays down the code of practice for plumbing services in buildings with a specific focus on the selection, sizing, and fixing of rainwater gutters and downpipes. It provides guidelines on material selection, pipe gradients, bracket spacing, and jointing techniques to ensure efficient roof drainage and prevent water leakage.

Establishes general requirements for the design, installation, and maintenance of plumbing systems in buildings.

Quick Reference Values
gradient for gutters1 in 150 to 1 in 600
minimum overlap at gutter joints50 mm
minimum diameter of downpipe50 mm to 75 mm
bracket spacing for cast ironMax 1.8 m
bracket spacing for PVCMax 1.2 m
Practical Notes
Ensure a uniform gradient towards the outlet to prevent water stagnation in the gutters.
Always provide gratings or wire mesh at the inlet of downpipes to prevent blockages from leaves and debris.
Allow for thermal expansion joints in long continuous runs of gutters, particularly for UPVC materials.
