A dry riser is a system of vertical pipes installed in multi-storey buildings that allows the fire service to quickly deliver water to higher floors in the event of a fire.
The system includes inlet connections at ground level, where fire crews connect their hoses, and outlet valves (landing valves) on each floor so firefighters can access water where it’s needed most.
Unlike wet risers, which remain permanently charged with water, dry risers stay empty under normal conditions.
They’re only filled with water by the fire service during an emergency.
Dry risers are crucial in buildings over 18 metres tall (typically six storeys and above) where using hose reels from ground level would be unsafe or ineffective.
A well-maintained dry riser system can save valuable time during a fire, improve response efficiency, and help protect lives and property.
Regular inspection and testing ensure these systems remain ready and reliable when needed most.
In buildings over 18 metres high, dry risers provide the fire service with instant access to water on every floor.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must maintain this system in efficient working order.
BS 9990:2015 recommends:
A visual inspection every 6 months
A full wet pressure test every 12 months
Our dry riser inspections include:
✅ Checking landing valves, inlet boxes, door locks, and cabinet seals
✅ Looking for corrosion, damage, vandalism, or blockages
✅ Annual wet pressure test to 10 bar for 15 minutes as specified by BS 9990
✅ Recording pressure loss, leaks, or mechanical faults
✅ Certification and written reports for your fire safety file
We also provide reminders when your next service is due and can combine visits with fire extinguisher servicing, fire alarm testing, emergency lighting checks, and more.

BS 9990 requires the system to be pressure tested to 12 bar for 15 minutes.
This test confirms the system is free from leaks and structurally sound.
BS 9990 states that test records must be retained and made available for inspection. These include the date of test, results, any faults found, and details of remedial work.
Generally, dry risers are required in buildings over 18 metres high. In taller buildings over 60 metres, a wet riser (permanently charged with water) is usually required.
BS 9990 specifies that inspections and tests should be carried out by competent persons with the necessary knowledge, training, and experience.
Due to the equipment and large amount of water required, risks involved, it's always recommended to use a specialist.
If a dry riser fails the test, BS 9990 requires it to be taken out of service until repairs are completed and the system passes a retest.
There is always a risk of water damage during pressure testing, especially if a hidden fault or leak is present.
However, by conducting a thorough visual inspection beforehand and having multiple engineers on-site monitoring the system, we aim to keep the risk of damage to a minimum and manage any issues quickly should they arise.
