What are risers?
Often referred to as rising mains, these are a system of pipe work that provides a readily available means to deliver considerable quantities of water throughout the building. This enables water to be provided at the correct pressure to upper floors of a building. The risers are then used by the fire service should they ever be required to enter your building.
What’s the difference between a Wet & a Dry riser?
Simply put a wet riser has a pump and is permanently charged with water, a dry riser does not. Wet risers are found in buildings 60metres above ground level. Dry risers are found in buildings above 18m tall or which have a span of greater than 60 metres.
