AN INTRODUCTION TO PLUMBING
Plumbing involves the installation of pipes and fittings for water, gas and sewerage reticulation. Water is divided into hot and cold and sewerage into waste water and soil water. Plumbing also includes the installation of rainwater and stormwater systems. Water supply and sewerage are two important aspects of plumbing, which play a very important role in the built environment and society as a whole. Plumbing is therefore one of the more regulated trades in the building industry, where only a registered licensed plumber can undertake plumbing work. The aim of this section is to provide technical information as a guide, and basic product knowledge to enable the reader to compile a specifcation and an accurate cost estimate of what a specific plumbing point or installation should cost.
