Intro
Proven Experience in Dry Riser Systems
We provide specialist dry riser inspection, testing, and remedial works, with experience across a wide range of building types and operating environments.
Our background includes complex and non-standard systems, live and high-risk sites, and projects where professional judgement and safety-led decision making were critical. The examples below highlight typical projects and demonstrate our approach to compliance, safety, and long-term maintainability.
Case Study Highlights
High-Security Aviation Facility – Dry Riser Remedial Works
- Large-scale replacement of 28 landing valves within a live, high-security airport environment
- Upgrade from threaded to PN16 flanged valves to improve long-term maintainability
- Full system testing and compliance achieved under restricted access conditions
Live Hospital Environment – Dry Riser System Modification
- Support provided to construction contractor during integration of a new building into an existing dry riser ring main
- Controlled drainage and staged recharging of a large horizontal system
- Continuous monitoring to ensure fire safety provision was maintained
Remote Heritage Site – Non-Standard Dry Riser Testing
- Testing of an 8-inch, 250metre dry riser main serving a historic hilltop site
- Temporary water supply provided using lake abstraction and centrifugal pumping
- System left charged at the request of the fire brigade due to size and refill time
New-Build Residential Block – Critical Inlet Non-Compliance Identified
- Unsafe inlet arrangement identified during pre-test inspection
- Pressure testing refused until compliant inlet and drain arrangement was installed
- System corrected, tested, and left fully compliant
Air Release Valve Non-Compliance – Resolved Prior to Testing
- Absence of air release valves identified during inspection
- Immediate remedial works completed to allow safe filling and pressurisation
- System tested and commissioned on the same day

Safety & Standards
Our Approach to Dry Riser Safety
- Pre-test inspections carried out prior to pressurisation
- Works halted where systems are unsafe or non-compliant
- Compliance with relevant British Standards and guidance
- Clear communication with clients, fire authorities, and stakeholders
- Focus on long-term system reliability and maintainability
