Dry riser system

An inlet breeching at ground level

provides the connection to the watersupply and can be installed in a

horizontal or vertical position. The

breeching has a 102mm (4 in)

screwed or flanged outlet and two

65mm (21/2 in) instantaneous male

inlets fitted with non-return valves and

drain valve as standard. It is housed in

a dry riser box, normally recessed into

the external wall of the building. Each

draw-off point from the dry riser is

fitted with a landing valve, situated in a

recess or cabinet. Manufacture is in

accordance with BS 5041 Part 2.

The valves have instantaneous

couplings to BS 336, for connection

to the fire-fighting hose.

The head of the dry riser should be

fitted with an air release valve which

ventilates pipework as water is

pumped in and closes automatically

by water pressure.

Wet riser system

This system is permanently

connected to the water supply.

Therefore inlet breeching and air

release valves are not required. Each

draw-off point requires a landing

valve, with either a rubber metal

seated valve. They are

manufactured in accordance with BS

5041 Part 1. The instantaneous

female outlet is to BS 336. Inletconnections may be screwed or

flanged as required.
