What we do
Need a wet riser? We will ensure a swift and smooth process taking you through the design all the way through to installation.
A wet riser installation is built for the purpose of fighting fires in high rise buildings (over 50m). At Triangle Fire we have extensive experience installing wet risers and understand the requirements that need to be met, in accordance with BS 9990.
Wet risers, like dry risers, are a system of pipework and valves installed on each floor, designed to transport water throughout the building.
What is a Wet Riser?
A wet rising main is very similar to a dry rising main. Wet risers are found in high-rise buildings, and allows water to be easily delivered to all floors. Unlike dry risers, the pipes in wet risers are full of water at all times.
How Does a Wet Riser Work?
A wet riser connects to an on-site water tank which is fed via the water mains and assisted by a fire pump. As the pipes in wet riser systems are filled with water 24/7, they require pumps which deliver the water to the outlets drawing water from storage tanks. The pumps will operate when the pressure drops once a landing valve is opened.
When Do I Need a Wet Riser?
Wet risers become mandatory when a building is over 50m as set out by Approved Document B (Fire Safety) of the Building Regulations. At Triangle Fire we take safety regulations very seriously and will ensure that we keep our clients informed on what requirements they are obligated to meet in order to avoid non-compliance.
