Inlet BreechingsWe provide a comprehensive range of genuine and fully compliant and conformant brigade equipment, for use by the Fire Brigade or other trained personnel, to provide a readily available means of delivering large quantities of water and/or foam to help to extinguish fire, or to prevent its spread. This range includes:
Inlet Breechings
Inlet breeching two way flanged 4" BSTD 46/54189

Dry riser inlet breechings are normally fitted in glass-fronted cabinets on the outside walls of buildings and have either two or four inlet connections. For special requirements, a single inlet breeching is available.
They are used to feed water into the rising main through 2 1/2" fire hoses. A 100mm (4") rising main uses a two-way inlet breeching and a 150mm (6") main uses a four-way inlet breeching.
Drain Valves to BS 5154
Normally fitted to inlet breechings but can be supplied separately.
Two-way Inlet Breechings
4" BSTD, 4" BSP parallel female or 100mm NP16 Ð can be mounted either horizontally or vertically.

Landing Valves
Landing valves used on dry rising mains should normally be of the gate valve type, but globe pattern valves are occasionally used. They act as outlets from the rising main and are fitted in easily accessible positions on each floor above the first floor of a building and sometimes in deep basement areas.
Dry Riser Gate Valves
With 2 1/2" instantaneous female outlet to BS 336, blank cap and chain, strap and padlock. Dry riser gate valves comply with the requirements of BS 5041:Part 2. Valves can be mounted in boxes complying with BS 5041:Part 4.
Globe Pattern Landing Valves (LP)
These screw-down stop valves are primarily used as hydrant outlets on wet rising mains, but are occasionally used on dry risers under special circumstances and after discussion with the fire brigade.
