Dry / Wet Risers & Fire Hydrants

Dry Riser Inspection   & Maintenance


Dry & Wet Riser Inspection & Maintenance

We offer scheduled maintenance and testing services for both wet and dry rising fire mains and fire hydrants, following the guidelines set out in BS9990. Additionally, we can supply Fire Brigade equipment as needed.

In emergency fire situations, having fully operational wet and dry risers is of utmost importance as they play a vital role in safeguarding lives and property. Regular testing and maintenance are crucial to ensure their effectiveness when needed most.

Failure to maintain and test these systems in accordance with relevant standards could lead to dire consequences, including potential prosecution.

Our experienced team carries out inspections and maintenance of wet and dry risers across various environments. For more information and guidance, please get in touch with one of our expert team members.

All our work is conducted in strict compliance with British Standards, specifically BS9990:2006.

We employ a dedicated dry riser testing vehicle for annual testing, which is performed by our skilled technicians. This testing includes the mandatory six-monthly visual inspections as outlined in BS9990.

Our technicians take safety precautions, cordoning off affected areas before mechanically inspecting and pressurising the system. After successful testing, we secure the system with padlocks and straps and issue the necessary certification.

It's important to note that underground hydrants also require regular inspection and occasional maintenance to ensure their functionality during emergencies. Since 1989, building owners and occupiers have been responsible for keeping hydrant systems in working order.

Dry & Wet Rising Mains

Dry and wet rising mains serve as crucial components for the Fire Brigade or trained personnel in effectively combatting fires and preventing their spread. They provide a readily accessible means of delivering substantial quantities of water for extinguishing or controlling fires.

Dry Risers: These are vertical mains installed in staircase enclosures or other suitable locations. They feature outlet valves on each floor and inlets at ground level, allowing the Fire Brigade to connect to the water supply. Dry risers are typically devoid of water when not in use, requiring the Fire Brigade to introduce water into the system when needed.

Wet Risers: In contrast, wet risers are pipes that are permanently charged with water. This water supply can be maintained through either a storage tank equipped with a boost pump or directly from the mains water supply. The continuous presence of water in wet risers ensures an immediate and constant supply, eliminating the need for the Fire Brigade to introduce water during an emergency.

Both dry and wet rising mains play vital roles in fire protection, enabling a swift and effective response in the event of a fire, ultimately contributing to the safety of buildings and their occupants.

Fire Hydrants

Fire hydrants serve as essential resources for Fire Brigades, providing access to a water supply for firefighting efforts. Typically, these hydrants are situated on public footways or highways and are owned, installed, and maintained by water companies.

However, in cases where fire hydrants are located on private property, the responsibility for their maintenance falls upon the owner, occupier, or operator of the site. This is particularly relevant for sites such as hospitals, university campuses, large warehouses, distribution centres, retail parks, private industrial estates, major manufacturing facilities, and similar locations.

Regular inspection and occasional maintenance of underground hydrants are essential to ensure their functionality during emergencies. These activities should align with the guidelines outlined in BS9990, which include inspecting and testing fire hydrants once a year to verify adequate water pressure and flow rates, with results duly recorded.

Since 1989, building owners and occupiers have been legally obligated to keep their hydrant systems in working order, emphasising the importance of timely inspection and maintenance.
