A Dry Riser is part of a fire suppression system in a building. It consists of a dry pipe that runs vertically / horizontally throughout a building with outlets on each floor. The main inlet is normally on the ground floor, where Firefighters can access it. Under BS9990-2015 and Irish standard I.S. 391:2020, property owners are obliged for dry risers to be tested annually.
How do we test dry risers?
InDepth Water Management are leading the way in Dry Riser testing for property owners, facility managers and the hospitality sector. So we are the go-to company for services of this nature.
After initial visual inspection, we test the riser with pressurised water at the inlet for 15 plus minutes. Under BS9990-2015 test pressure is 12bar for 15min. and Irish standard I.S. 391:2020 test pressure is 15bar for 15min. If there is a loss in pressure then the system is deemed to have failed.
We check all inlets and outlets for leaks and replace missing or faulty items. If faults are identified, then we test the pressure after completing repairs once again before certification is issued.
