Typical Dry Riser pipe work & valve sets


A Dry Riser is a system of pipes and valves installed in tall buildings or building with restricted access that enables the fire brigade to pump water to specific predetermined points within the building. Dry Riser systems have an “inlet” valve typically located outside the building at ground level in a lockable box with wired glass. It is at this point the brigade would connect their water supply and pump it into the building, connecting a hose to an “outlet” valve at the required level to fight a fire.

The buildings “Responsible Person” (RP) is required to maintain the system to BS 9990:2015 – Code of practice for non-automatic fire fighting systems in buildings, and ensure maintenance frequency and procedures are in accordance with BS 9999:2008 – Code of practice for fire safety in the design, management and use of buildings, or as specified by the buildings Fire Risk Assessment (FRA).

BS 9990:2015 requires the system to undergo an annual static pressure test and inspection and a six monthly visual inspection, by a competent person. Thus ensuring the Dry riser system is maintained and functioning correctly for the fire brigade at all times.
