Wet & Dry Risers

Dry Rising Mains
Dry rising mains are intended for use by the fire brigade or other trained personnel. They are vertical mains fitted into staircase enclosures or other suitable positions, with outlet valves on each floor and inlets fitted at ground level to enable the fire brigade to connect to the water supply. We also provide a specialist annual pressure testing service.

Wet Rising Mains
Wet risers are installed into buildings and are permanently charged with water. The water is delivered either through the town’s main water supply or a dedicated water supply such as a pump and storage tank set up.

The current standard for the installation of dry and wet riser Systems is BS9990:2015
