Dry Risers
Dry risers are normally dry but are capable of being charged with water by pumping water from a Fire Service appliance. An air-release valve is fitted at the highest point to allow the dry riser to become fully charged. A hydrant outlet valve is fitted to each floor to allow the Fire Service to connect their hoses.
Dry Riser should be checked as follows:
- Should be checked and serviced twice a year
- Pressure tested to 150psi or 10 bar
- All inlets and outlets inspected
- Flow tests conducted
