Reduce Risks With Wet & Dry Risers
Precision-installed. Compliantly maintained. Always ready.
Designed and fitted with precision in accordance with BS 9990 regulations. Choose Thor Fire Ltd, specialists in the installation and servicing of wet and dry risers.
Dry Risers are an essential part of any building design where the height of the building exceeds 18 metres from the fire brigade access level to the top floor. They are also required where there are floors more than 10 metres below ground.
In an emergency, the fire brigade connects to the ground floor inlet to pressurise the pipe, then accesses water from outlet valves near the fire.
This setup…
- Speeds up response time
- Reduces the need for heavy hoses
- Creates safer conditions for evacuation and firefighting
For taller buildings over 50 metres, wet risers are required – these are kept permanently charged and ready to use.
Whether you need a full installation or regular servicing, our engineers ensure your riser system stays compliant, operational, and always ready.
WET RISER
What Is A Wet Riser?
A wet riser is a water pipe kept constantly filled and pressurised. It is supplied by either a mains pump, a storage tank and pump or a mains pressure supply.
Generally buildings above 60m high will have a wet riser. This can be identified from the outside as there will be no visible pipework or inlet for the fire brigade. With wet riser systems internal valves on landings stating ‘Wet Riser Outlet’ can be found, usually resembling taps. These can also be protected inside wired glass or lockable metal boxes. At Thor Fire Ltd, we offer a complete design and installation of new wet riser systems for properties and buildings in the UK.
