At Magni Fire, we specialise in the installation and maintenance of Wet and Dry Riser Systems, providing essential fire protection for buildings of all sizes. These systems are critical for ensuring that water can be delivered quickly to upper floors in the event of a fire.

Installation, Servicing, and Maintenance
‍

Dry Riser Systems

Typically found in buildings over 18m tall, dry riser systems consist of a network of empty pipes that are ready to be filled with water when needed. These pipes are strategically placed within fire-fighting shafts, protected lobbies, staircases, or enclosures, ensuring easy access for the fire brigade. With an inlet at street level and outlets (landing valves) on each floor, dry risers allow the fire service to connect hoses and tackle fires on upper floors quickly. When not in use, dry risers remain empty and are only charged with water by the fire service when required.

‍

Wet Riser Systems

Wet riser systems, on the other hand, are continuously filled with water and are designed for taller buildings, typically over 50m. By maintaining a constant water supply, these systems provide immediate fire protection to upper floors, allowing for a faster response in case of an emergency.

‍

Servicing and Maintenance

Magni Fire offers comprehensive servicing and preventative maintenance for both wet and dry riser systems, fully compliant with the BS9990:2015 Code of Practice for Non-Automatic Fire Fighting Systems in Buildings. Regular servicing is essential to ensure these critical systems remain in top working order.

‍

Scheduled Service Visits

British Standards recommend servicing every 6 months. One of these visits includes a major service (wet test), where hydraulic pressure tests and other comprehensive checks are performed. The other is a visual inspection to ensure the system is in good condition and hasn't been tampered with, especially given the risk of vandalism in accessible areas.

Major Service

The annual wet test includes a full hydraulic pressure test to ensure the system is ready for emergency use.

Visual Inspection

Every 6 months, a visual inspection helps identify any issues that could compromise the system's functionality, ensuring peace of mind.
