Wet riser vs dry riser

Many commercial, wet riser vs dry riser, industrial and non-residential properties rely on wet and dry risers as a key part of their fire safety procedures. Wet and dry risers are a key part of fire safety protection for all multi-storey buildings. Both risers are designed to provide firefighters with easy access to water when tackling fires in tall buildings, helping them to extinguish them and prevent the blaze from spreading.

Although wet and dry riser systems are a common spot, especially on commercial and industrial premises across Singapore, not many people really understand what they are and how they work. Wet and dry riser systems are made up of a network of valves and pipes that enable fire fighters to pump large volumes of water to the top of high rise buildings or areas that are hard to access with other common systems during fire emergencies. Due to the high pressure required to pump water onto tall buildings, wet riser systems are equipped with duplicate automatic pumps and well as tanks for storing water. The water for the tanks comes from the city mains but, you could also have an alternative water source. Dry riser systems remain empty but, have water inlets at the ground level for supplying water during a fire threat.

Comprehensive fire protection is about much more than just sprinkler systems. But what are they? How can they improve safety? And, perhaps most importantly, is it a legal requirement to have one of these systems installed in the properties you manage? Both systems are designed to provide a rapid source of water to upper floors should the need arise. Both systems must also — by law — be tested every 12 months. This is often the responsibility of the property owner or managing agent. At Eversafe, we offer a maintenance service that can handle all that for you. Despite all these similarities, there are some significant differences between the two systems. Dry risers are a legal requirement in buildings more than 18m tall. Dry riser pipe networks connect a ground floor inlet usually an external inlet with multiple internal outlets located across the higher floors of the building.

They can also be found in environments with limited access or with compartmentation issues such as multi-level basements or hospital corridors.

Simple but effective, sprinklers have been used for around years. According to statistics, no person has lost their life to fire in the UK where Sprinklers have been installed. We also have specialist equipment to cut and re-thread sections of large diameter pipe or to fit collars to pin-hole leaks. You can contact us regarding any concerns you may have about the installation or maintenance of your Sprinkler system, or to request a site survey in order to provide you with a quotation. Dry risers otherwise known as fire mains are used in buildings over 18m in height. They assist the Fire Service by pumping water to landing valves located on every floor.

Wet riser vs dry riser

Dry risers and wet risers are both fire protection systems used in buildings, but they have different purposes. Dry riser systems are left empty when not in use, water is only introduced to them when firefighters connect a hose to the inlet breeching valve on the ground floor. They are usually installed in buildings where water cannot be permanently stored due to pipes easily freezing. Wet riser systems are permanently stored with water, making it immediately available for firefighters in the event of a fire. The water supply for a dry riser is provided by the fire brigade when needed. The hoses are connected to the inlet valve on the ground floor and water is pumped into the system to reach the necessary location. However wet risers are connected to a permanent water supply, such as the buildings mains supply. Firefighters therefore do not have to rely on an external water source.

Dry risers can be found in buildings over 18m above ground level, where there is an excessive distance between entrances and the upper floors. We may request cookies to be set on your device.

What is it: A dry riser is an empty pipe that can be externally connected to a pressurized water source by firefighters. Take a look at the areas we cover to find out more.

Still, there may be nowhere in a sprinkler system with so many necessary components per linear foot as at the fire sprinkler riser. In systems both large and small, fire riser assemblies prevent pressure from escaping the system, make repairs easier, and control the flow of water to sprinkler heads.
