Wet & Dry Risers
Wet and Dry Risers use vertical pipes in a building for fire-fighting purposes and need to be installed by trained personnel like our team at MacDonald Martin. We can inspect and advise you in regards to the design and installation of Wet and Dry Risers, as well as designing a solution to suit specific building requirements, if required.
What are Wet and Dry Risers?
Wet Risers: Installed for fire-fighting purposes via vertical pipes, permanently charged with water form a pressurised supply and fitted with landing valves at specific points. If your floors are more than 50m above fire service access level, wet fire mains should be installed to ensure water is immediately available to all levels in the event of a fire.
Dry Risers: Installed for fire-fighting purposes via vertical pipes, fitted with inlet connections at fire service access level and landing valves at specific points. Normally these are dry, but are capable of being charged with water usually pumped by fire and rescue service appliances.
