Wet and Dry Riser Testing
If you are a building Landlord or Manager responsible for business premises and if your building is 18m or more in height your building should be fitted with Dry Risers. Your Dry Risers require an annual pressure test and a 6-monthly visual inspection.
Our trained and experienced crews with our fire service appliances are equipped to perform annual hydraulic pressure testing on your Dry Risers, ensuring they are tested to the full required pressure (as stated in BS 9990/2015), which many other companies are unable to carry out
What is a Wet and Dry Riser?
A dry riser is a main vertical pipe intended to distribute water to multiple levels of a building or structure as a component of the fire suppression systems. The pipe is maintained empty of water. The dry riser is the opposite of a "wet riser" system where the pipes are kept full of water for manual or automatic fire fighting operations. Dry risers have to allow access to a fire appliance within 18 m of the dry riser inlet box. Dry risers in occupied buildings have to be within a fire resistant shaft, usually one of a building's fire escape staircase enclosures.
The riser is charged to 12 bar of pressure and checked to see if its maintained its pressure for 15 minutes, meanwhile our technicians are checking the main, landing valves and joints for leaks on all floors.
In the event a problem is found, our skilled technicians can refurbish your dry riser main and refit new seals, landing valves, inlet breechings and cabinets if required.
