Dry & Wet Riser Testing

A Wet Riser is a pipe kept permanently charged with water available either direct from a storage tank, via a booster Pump, or fed directly from the towns main water supply.

Dry Riser and Wet Riser Mains are intended for use by the Fire Brigade or other trained personnel and provide a readily available means of delivering considerable quantities of water to extinguish or to prevent fire spread.

The annual testing and maintenance of both Dry and Wet Risers is the responsibility of the property owners or Managing agents. British Standard BS 9990:2006 recommends that the system is visually inspected every 6 months and serviced annually to ensure that the equipment is ready for immediate use in an emergency. In addition, it is recommended that a ‘full wet test’ be carried out annually, comprising of a full wet pressure test to 10 bar subjecting the main to a full working test.
