Breeching inlets are installed outside the building or any easily accessible area in the building for fire brigade personnel to access the inlet. This inlet is used by the fire brigade personnel to access water. It is normally dry but is used to pump water by charging using fire fighting equipment.Normally there are two types of inlet breeching available, one is 2-way another is 4-way. The 2-way version has 2 x 2½” Instantaneous male non-return valve inlets and a 4″ outlet while the 4-way inlet breeching has 4 x 2½” Instantaneous male non-return valve inlets and a 6 outlet along with 1″ drain valve.
There are three main types of breeching inlets:
1. Dry breeching inlet: used in dry riser systems where the water supply is not permanently connected to the system, and water is supplied through the inlet only when needed.
2. Wet breeching inlet: used in wet riser systems where the water supply is permanently connected to the system, and water is always present in the system ready to be discharged through the inlet.
3. Combined breeching inlet: used in combined dry and wet riser systems where the inlet can be used as both a dry and wet supply depending on the needs of the system.
