DRY RISER & FIRE HYDRANTS

Dry Riser Testing

The person responsible for a building or site is legally required to maintain all fire fighting
equipment, including dry risers. The British Standard Code of Practice BS9990:2006 requires
a full annual pressure test and six monthly visual check for dry risers for buildings above
18 metres and below 60 metres (buildings over 60 metres/18 storeys require wet risers).

The standard states that inlets, landing valves, drain valves and landing valve boxes should
be inspected every 6 months and recommends that wet tests be carried out annually when
the main can be checked for leaks.

BS9990:2006 also states that maintenance and repairs should be carried out by a competent
person. With Lindum Fire Services Ltd you can be confident that all work will be carried out in
accordance with the British Standards. We are registered with BAFE, members of the British

Dry Riser Testing - Maintenance & Servicing

Dry Risers are a important piece of fire protection equipment for buildings above 18 metres.
They play a critical role in delivering considerable quantities of water in a high rise building.
They can however be prone to serious neglect and vandalism so it is important to have them
regularly maintained and serviced. We will carry out a full annual pressure test and six monthly
visual check to the current British Standard Code of Practice BS9990:2006 using our own dry
riser testing appliance.

pressure test will be carried out before certification is issued.
