Dry Riser Testing & Servicing

Responsible Persons must ensure firefighting equipment and facilities are maintained where fire safety legislation applies. While legislation does not prescribe every testing interval, following the relevant British Standard, BS 9990, helps demonstrate that dry riser systems are appropriately inspected, tested, and serviced in line with recognised regulations for dry risers.

Recognised guidance, including the British Standard BS 9990, recommends visual inspections every six months to check for signs of damage or deterioration, together with annual pressure testing. Together, these form part of a programme of regular testing and maintenance to help ensure dry riser systems remain ready for use in the event of a fire. Testing frequencies should always reflect the building, its fire safety arrangements, and the manufacturer's recommendations.

Dry riser pressure testing uses specialist testing equipment to verify that the pipework, landing valves, inlets, and outlets remain watertight and capable of operating correctly. The system is pressurised to identify leaks, pressure loss, or other defects that could affect performance or require remedial work.

Dry riser testing and maintenance should be completed by competent engineers with appropriate experience of firefighting water systems. Using a competent provider helps ensure dry riser systems remain reliable for the Fire and Rescue Service and continue to support your building's wider fire protection strategy.

Inspection records, pressure test certificates, servicing documentation, and details of any remedial works should be retained as part of the building's fire safety records. Maintaining accurate records of dry riser testing and maintenance provides an auditable history of compliance and supports Fire Risk Assessments, audits, and regulatory inspections.
