Wet & Dry Risers

Wet & Dry Risers

A rising main is a system of pipework and valves intended for use by the Fire Service, allowing the easy delivery of water to all floors within a high rise building. Eliminating the delays caused by firefighters having to drag fully charged hoses throughout tall buildings – they are a vital lifesaving solution. Usually fitted within a cabinet on each floor, they can either be permanently filled with water (Wet Riser) or left dry (Dry Riser).


Wet and Dry Risers are often prone to neglect or vandalism resulting in damage / leaks which can cause the system to fail. In addition to the damage that leaks can cause to a building, there can be severe penalties should the system fail to operate correctly for the Fire Service. BS 5306 Part 1 – 1976 recommends Dry Risers are visually inspected every 6 months with a pressure test annually. BS 5306 Part 1 – 1976 also recommends that Wet Risers receive a visual inspection every six months, have two electric pump inspection services each year and also at least one flow test per annum (if applicable).
