Why Do You Need a London Dry Riser company?

When do you need one? There is a need to install a functioning and non-automatic fire-fighting system in London buildings, especially tall ones. The other one is the wet riser system.

This is a rising main composed of a vertical pipe that has an inlet box that runs on the outside of the building and dry riser outlets which are placed on every floor in the building. With this system in place, firefighters would find it easier to fight fire in buildings that have floors above eighteen meters to the ground and have about six to seventeen stories.

The riser would relieve firefighters the stress of dragging a hose from their service truck up the stairs to get to a floor in the building. This would help save time and above all the lives of many.

Before you go about installing one in your building, you should know that there are regulations that guide the design and installation of a dry riser. We have discussed some of these regulations below.

Maintenance and Testing

UK Fire crews understand the a dry riser’s layout, function and how they operate. They also have knowledge of any risk involved.

If a building that’s fitted with a riser cupboard or dry riser is reffered to as a special or specific special risk (PRM/SSRI); then, detailed information on the riser’s size, location and performance limits needs to be noted down in any risk assessment.

It’s a property owner’s responsibility for the annual testing and maintenance of Dry and Wet Risers.

There’s various UK FRS that are allowed in the assistance of owners with testing of Dry Risers.. However, there may be a fee invloved with this.

British Standard 5306: Part 1 1976 (Revised by BS9990) states that a system should really be inspected ideally every 6 months.

Also, this should be serviced annually to make sure that the equipment is ready for immediate use in an emergency such as a fire.

Wet Riser Installation

At Dry Riser Solutions, we are Wet Riser installation and design experts. We collaborate with M&E contractors to fit and test wet riser drains, Isolation valves, PRVs and of course the Main riser pipework.

  • A test riser must be  installed by an installation expert along side the wet riser. Then, this is used for the evacuation of water from the wet riser – during a flow test.
  • Your wet Riser System is installed with Landing Valves. These locations are chosen where they will be positioned on each floor. A wet Riser can be installed up to and over 50m. The wet riser installation system is designed to provide high pressure flow at the upper floors.
  • PRVs are also installed on every floor of the building. Why? In the event of an emergency this makes sure that the required optimum pressure is delivered on each floor.

Our dry riser will work with you to supply and install the pipework, test drain, PRVs and connecting to the pump ready for commissioning.
