What is a DRY RISER?
A dry riser is a vital component of fire safety systems in buildings, particularly in high-rises and large structures. It is essentially a network of pipes and valves that allows the Fire Brigade to access a reliable source of water on each floor of a building in the event of a fire emergency. Here’s how it works:
Pipes and Valves
Dry risers consist of a series of vertical pipes, typically made of steel, and a set of valves at various levels of a building. These pipes are usually empty (hence the term “dry”) and do not contain water when not in use.
Fire Hose Connection
On each floor, there is a fire hose connection point. This connection point allows the Fire Brigade to attach their hoses to the dry riser system.
Fire Brigade Water Supply
In the event of a fire, the Fire Brigade connects their hoses to the dry riser outlet on the floor closest to the fire. They then pump water into the dry riser system, pressurising it.
Water Distribution
The pressurised water is then distributed through the dry riser’s network of pipes to various points on that floor, where the Fire Brigade can connect their hoses and access water to extinguish the fire. This eliminates the need to run long hoses up the building from the ground floor, which would be impractical and time-consuming in tall buildings.

We operate across the entire UK, serving major national mechanical contractors and small independent builders.
Dry Riser Systems
Dry risers are vital pipe systems that can only be externally connected to a pressurised water source by the Fire Brigade or trained personnel. These vertical pipe runs are designed to distribute water to various levels of a building through landing valves or structures, forming an integral part of fire suppression systems.
Additionally, these systems can be deployed horizontally to reach buildings with limited access from the main road.
Dry Riser Inspections
In the UK, all buildings necessitate some form of fire protection, leading to the widespread use of dry risers, especially when a building’s water pressure is insufficient for effective fire suppression. To expedite water distribution to the fire source, the Fire Brigade use dry risers as the quickest and most efficient method. UK regulations stipulate that dry risers must allow fire engine access within 18 meters of the external dry riser inlet breaching valve.
Moreover, dry risers in occupied buildings must be housed within fire-resistant shafts, typically within one of a building’s fire escape staircase enclosures. All our systems are meticulously designed and installed in compliance with the prevailing BS9990 2015 standards.
