DRY RISER:
Dry Riser Systems are installed in buildings for fire fighting purposes by trained personnel and which are normally dry and are capable of being charged with water by pumping from Fire Service Appliances
Dry Riser Systems are installed complete with an inlet breeching connector at Ground Floor or at Fire Service Access Level and with Landing Valves at specified points on each floor
Dry Riser Systems are installed up to 50m above the Fire Service Access Level
An air release valve is fitted at the highest point to enable the riser to be fully charged.
WET RISER:
Wet Riser Systems are installed in a buildings for fire fighting purposes by trained personnel and which is then immediately available for use on any floor at which a fire hydrant globe valve (also known as a landing valve) is provided.
Wet Riser Systems are installed complete with Landing Valves at specified points on each floor.
Wet Riser Systems are installed up to and above 50m subject to the system being designed to provide adequate flow and pressure at the upper floors
If the mains pressure is higher than maximum brigade operating pressure it is necessary to use pressure regulating landing valves.
