All buildings above 18 metres high have Dry risers installed. These are used for conveying water to strategic locations within a building for the use of fighting fires.

Wet and Dry risers should be checked and serviced twice a year. The first test comprises of a wet pressure test to PSI or 10 bar for a minimum of 15 minutes. All inlets and outlets are checked for leaks and any missing or faulty items reported. Flow test are also carried out at this time.

A certificate will be issued on completion to inform the client whether the riser has passed or failed.

The second test is a minor service of all the moving parts, which is also a British standard requirement. All testing on wet / dry risers is carried out to BS 5306 part 1.
