Wet and Dry risers are used by the Fire Service to provide a readily available means of delivering considerable quantities of water. The choice of wet or dry riser will be dictated by the type of building.
Wet Risers
Our wet riser systems store water at all times, allowing for a constant supply of water for fighting fires throughout any commercial building. Each system houses a glass valve that shatters when the room temperature rises above 68°C and only activates sprinklers in the zone of fire.
Dry Risers
Very similar in function to our wet risers, our dry riser systems do not store water at all times. They are left empty so that the fire brigade can pump an extinguishant of choice through them to effectively and quickly combat any fire.
Essentially a system of pipes that run through your office building, hotel or other commercial building, our dry and wet risers allow a supply of water for fighting fires throughout a building.
Our dry and wet risers can also be quickly and easily connected to any fire sprinkler systems you already have in your property or any that we are installing for you. This will ensure that as soon as a fire is detected, your sprinkler systems will be swift and effective in dealing with the fire.
With offices in Surrey, Somerset and Kent, we have experience of installing and maintaining high quality fire and security systems for commercial and industrial customers throughout London and the surrounding counties, at very competitive prices.
It is important that wet and dry riser systems are regularly serviced and maintained as failure to do so can result not only in failure but potential prosecution.
Artius Property Protection has the support structure and capabilities to successfully maintain and regularly test both wet and dry riser systems.
Installation
Site engineers will fabricate on site and make sure installation is done to design drawings. Any alterations will be dealt with as soon as they arise. By law dry risers have to have fire engine access within 18m of the dry riser inlet box and have to be housed in a fire resistant shaft. In commercial properties this is usually under the staircase of a fire exit.
After completion of the installation the riser will be hydraulically pressure tested to the standard BS990/2015. A test certificate will be issued.
Servicing & Maintenance
A visual inspection every 6 months and a wet test yearly are required. All buildings which have fire risers must comply with the standard BS 9990/2015. Failure to do so may invalidate your insurance.
Annual pressure testing
For dry risers this normally entails connecting the inlet to a pump and water supply. The system is then completely charged with water to a pressure of 10 bar measured at the inlet for a period of at least 15 minutes. During this period an inspection is made to ensure that there is no leakage of water at any of the joints or landing valves. Once the pressure test is completed the system must be drained so that it is left ready for immediate use. In the event of system failure due to inability to hold pressure for the recommended 15 minutes at 10 bar (at the inlet), a retest will be required.
For wet risers there are additional checks, on cleanliness of storage tanks, booster pumps and associated mechanical and electrical equipment.

Maintenance & Remedial Repairs
Should the system’s pipe work be altered (e.g. building alterations, extensions etc. then a full re-commissioning flow test will be required).
