Dry Risers and Hydrant Testing

What you need to Know 


Dry risers should be inspected visually every 6 months and fully tested annually to BS9990/2015. Call today 1800331100 to ensure your building complies.


Dry Riser is a system of valves and pipework which enables the Fire Brigade to pump water on to the upper floors of a building. All buildings between 18 metres and 50 metres are required to have a dry riser system installed. The dry riser pipe is maintained empty of water. All building over 50 metres are required to install a wet riser system.


A Wet Riser is a system of valves and pipework which are kept permanently charged with water. A dry riser enables the fire brigade to connect fire hoses to the dry riser inlet box and deliver water to the landing valves of the dry riser stack, which are situated on each floor. This saves critical time for the fire brigade.


Dry Risers must have fire engine access within 18 metres of the dry riser inlet box.
