Dry Riser Mains are a readily available means of storing and transporting substantial quantities of water to extinguish or prevent the spread of fire. They are intended for the Fire Brigade or trained personnel use.
Installation of Dry Risers in accordance with BS9990:2015
Dry Risers combine the vertical mains which are fitted into staircase enclosures (or other suitable positions) with outlets installed at ground level to enable the Fire Brigade access to the water supply.
Firecom’s industry qualified design team endeavour to create a full design specification as well as calculate accurate installation costs for client transparency. This is achieved through either scale drawings or a free full site survey.
At Firecom our highly trained mechanical engineers are committed to providing the best possible service ensuring speed of installation, quality of workmanship, and competitive pricing.
Rest assured that all on site personnel are accredited to the Construction Skills Certification Scheme (CSCS). This consists of basic and advanced site skill training and encompasses Health and Safety awareness (as detailed within the CSCS Scheme Booklet). All engineers hold IPAF (International Powered Access Federation) and PASMA (Prefabricated Access Suppliers and Manufacturers Association) licenses.
Following installation, we will complete a full wet test of the system in accordance with BS9990 guidelines. In the event of a successful completion certification will be awarded. Additionally, all installation work comes with a 12-month warranty guarantee so you can have complete confidence in your system.

Service of Dry Risers in accordance with BS9990:2015
To maintain compliance with BS9990 Dry Risers must be serviced every 6 months. An initial test must be conducted: commonly known as the ‘wet test’ and separate from this, a visual inspection every 6 months. This applies to all buildings 18-60 metres in height – buildings over 60 metres require Wet Risers.
The Wet Test
Firstly, it is important that before any testing takes place all landing and air release valves are in good condition, have not been tampered with, and are closed shut to prevent the escape of air and water.
Following the valve check, one of our skilled engineers will fill each riser stack with water (these are the pipes that rise through the building with a landing valve on each floor). Some companies use the street hydrants, however, this water should only be used by the Fire Brigade and not for the benefit of testing companies.
Therefore, Firecom engineers come equipped with their own water bowser in order to perform the correct services of the Dry Rise System.
Next, the Dry Riser is pressurised to 10 bar. The riser must hold water at this pressure within the pipework stack for 15 minutes in order to be certified.
On completion of the test, the water is then discharged back into our engineering teams water bowser using the drain down valve for future testing purposes.
Some premises have multiple Dry Risers and each stack will receive the same test and certification accordingly. Should any remedial works be required, the Firecom team will provide a prompt quote for the recommended work to bring your system back to the required standard.
All remedial works should be carried out by a competent, fully trained, and accredited engineer. Firecom’s engineers are fully qualified to carry out this work.
Firecom also provides a 24-hour 7 day a week callout service should you have any urgent issues giving you peace of mind that your Dry Riser systems will always remain compliant.
