Dry riser testing, maintenance, and inspection services in London and the UK
What is a dry riser?
A dry riser system consists of a series of pipework and valves that normally run from the base of a building, vertically up to the highest floor or roof area. In premises with a complicated layout, they can sometimes also run horizontally in order to provide the fire service with what’s known as a landing valve where they can connect their hoses to.
What signs are displayed on a dry riser?
Dry riser systems are usually clearly marked with signage, and will usually have the outlets located in prominent positions within purpose made cabinets. These cabinets, or inlet boxes, will also have a sign fixed to them so that they can be clearly identified.
Why are dry risers required?
These systems are important, as without them the fire brigade would have to run their hose up flights of stairs or around lots of obstacles, which could cost them vital time in the event of a fire.
How are rising fire mains regulated?
It is very important that they are tested, maintained and inspected according to the regulations (BS 9990:2006). A test would normally be carried out by a specialist dry riser testing company, with a six monthly visual inspection, and an annual static pressure test (hydraulic inspection) being the required by the British Standard
What do the different tests consist of?
A six monthly inspection would involve a specialist engineer coming to your site and carrying out a visual inspection of your entire system.
An annual test and inspection would initially involve the same visual inspection as before, but would also require the entire installation to be pressurised with water (to a pressure of 10 Bar), normally using a fire engine or other specialist testing vehicle.
