Fire main

Code of Practice for the Provision of Premises Information Boxes in Residential Buildings, Version 1, published in December 2020 by the Fire Industry Association (FIA) and the National Fire Chiefs Council (NFCC), defines a fire main as a: ‘Water supply pipe installed in a block of flats for firefighting purposes, fitted with landing valves at specific points. The main may be ‘dry’, in which case it is fitted with inlet connections at fire and rescue service access level, so that it can be charged with water from pumping appliances. In tall blocks, the main is ‘wet’ and is permanently charged with water from a pressurised supply.’

Planning Gateway One - Glossary, published on the Planning Portal, defines a fire main as a: ‘Water supply pipe, fitted with an outlet and control valve at specified points, installed in a building for fire-fighting purposes.’
