Wet & Dry Riser Servicing in Essex
A working wet or dry riser system gives firefighters fast access to water when every second counts. At Assured Fire & Security, we provide professional wet and dry riser servicing in Essex for commercial buildings, residential blocks, schools, warehouses, and public sector sites.
Dry risers and wet risers play a key role in fire protection, especially in taller buildings where fire crews cannot easily run hoses from ground level. Without regular testing and maintenance, these systems can fail when they are needed most.
Our engineers carry out complete dry riser maintenance, dry riser testing, wet riser servicing, and inspections across Essex. We have supported local businesses and property managers for more than 30 years, helping keep buildings compliant, reliable, and ready for emergencies.
Servicing and Maintenance of Dry Risers
Regular servicing and maintenance of dry risers is a legal requirement for many multi-storey buildings. It also helps protect occupants, firefighters, and property during an emergency.
Under BS9990:2015 standards, dry riser maintenance and wet riser maintenance should include:
- Six-monthly visual inspections
- Annual pressure testing
- Checks for leaks, corrosion, and damage
- Valve and landing inlet inspections
- Cabinet and signage checks
- System performance testing
Our experienced engineers carry out thorough dry riser inspections and wet riser inspections to make sure every part of the system is functioning as intended.
During a dry riser service, we inspect:
- Pipework and joints
- Landing valves
- Inlet breeching valves
- Pressure gauges
- Washers and seals
- Drain valves
- Access cabinets and locks
- Identification signage
For annual dry riser testing, the system is pressure tested to confirm it can operate safely during a fire. We also carry out wet riser testing to check pressure levels, pumps, tanks, and overall system performance.
Once complete, we provide a full maintenance certificate and clear recommendations if repairs are needed. If we identify faults or worn components, our team can arrange repairs quickly to reduce downtime and maintain compliance.
Keeping up with dry riser servicing is not just about meeting regulations. Faults such as leaking valves, corrosion, or low pressure can stop firefighters from accessing water during an emergency. Routine inspections help spot problems early before they become serious or expensive.
As part of a wider fire safety plan, riser maintenance should work alongside regular fire assessment reviews and ongoing fire alarm servicing to ensure all systems support a safe evacuation and emergency response.
Wet Riser Servicing in Essex
Wet risers are permanently charged with water and are commonly installed in high-rise buildings where immediate water access is essential. Because these systems remain pressurised, regular wet riser servicing is vital to ensure they operate correctly under emergency conditions.
At Assured Fire & Security, we carry out complete wet riser maintenance for buildings across Essex. Our engineers inspect all key components, including pumps, valves, tanks, outlets, and pressure controls.
Wet riser systems can develop faults over time due to wear, corrosion, pressure loss, or damaged components. Regular wet riser inspection and testing helps prevent unexpected failures and keeps your building compliant with current fire safety standards.
We work with:
- Apartment blocks
- Office buildings
- Schools and colleges
- Hospitals and care homes
- Industrial units
- Local authority buildings
Our team understands the importance of minimising disruption. We schedule servicing around your building requirements wherever possible and keep communication clear throughout the process.
If your system fails a test or requires urgent repairs, we respond quickly to help restore compliance and reduce risk.

Frequently Asked Questions
What is the difference between dry and wet risers?
Dry risers are empty pipes filled with water only during a fire. Wet risers, on the other hand, are always filled with water under pressure, allowing for immediate use in emergencies.
How often should wet/dry risers be serviced?
Both dry and wet risers require visual inspections every six months and annual testing with certification to meet BS9990 standards.
What happens during a wet/dry riser service?
Servicing involves inspections, testing, and component checks. Our engineers ensure the system functions properly and issue a compliance certificate.
Why is regular maintenance important?
Regular servicing and maintenance of dry risers and wet risers ensures system reliability, reduces the risk of faults, and helps you avoid penalties for non-compliance.
What buildings require dry or wet risers?
Dry risers are usually required in buildings over 18 metres tall. Wet risers are commonly installed in buildings over 50 metres where faster water delivery is needed.
What happens if a riser system fails inspection?
If faults are found, we provide a detailed report explaining the issue and any repairs required. Our engineers can carry out remedial work to help restore compliance as quickly as possible.
How do wet and dry risers fit into a building’s overall fire safety strategy?
Wet and dry risers are crucial for firefighting access, especially in multi-storey buildings. As part of a comprehensive fire assessment, their condition and compliance should be reviewed regularly alongside other safety systems. Coordinating riser maintenance with fire alarm servicing ensures all critical fire protection measures are functioning together to support a safe and effective emergency response.
