Dry Riser Testing
What is a Dry Riser?
A Dry Riser is a system of valves and pipework which enables the Fire Service to pump large quantities of
water on to the upper floors of tall buildings for fighting fires.
Why should testing be carried out?The person responsible for a building or site is legally required to maintain all fire fighting equipment, including dry risers. Often buildings such as large blocks of flats are targeted by criminals and vandals who remove and damage parts of the dry risers rendering them potentially useless in the event of fire. Systems that are not maintained are at risk of parts becoming ceased or may fail under pressure.
How often should a dry riser be tested?BS9990:2015 requires dry risers to be tested under pressure annually with a visual inspection every six months.
We schedule service visits bi-annually and are split into two types of service visit:-
- Inspect all parts of the system for compliance with BS9990:2015
- Fully open and close each landing valve and grease mechanical workings
- Replace any worn or missing parts including washers, straps, padlocks, gaskets etc.
- Charge the system with water and pressurise to 10 Bar
- Monitor for a period of no less than 15 minutes
- Drain all water from the system and replace seals, caps and plugs
- Provide a detailed test report and certificate
- All of the above without the pressure test
