Similarly to dry risers, wet risers are installed in buildings for the purpose of saving lives and protecting buildings in cases of fire emergencies. They are a vital source for firefighting reasons, enabling them to gain access to a large amount of water throughout tall buildings.
Acting slightly differently to dry risers, wet risers have installed on buildings above 50 metres. They are constantly charged with pressurised water from an in-house pump, with landing valves installed at specific locations on each floor. This allows for a high-pressure flow of water to be received on the upper floors of large buildings, ultimately aiding and assisting firefighters tackling a blaze high up.
