Dry Riser Maintenance.
Trust Nationwide to maintain your Dry Riser system and keep
it running
smoothly.
To keep the dry riser maintained and functioning correctly
an engineer will visually inspect the entire system from
roof to ground level. To test the riser it needs to be
connected to a water supply at the inlet and pressurised to
10 bars. This should last at least 15 minutes.
Whilst this test is being carried out, the engineer will again check the entire system for any sign of leaks or damage. Any excessive loss in pressure while the test is in progress will be deemed as a fail. On completion of system validation the dry riser is fully drained.
There are also a number of things you can do to help such as immediately reporting any signs of wear or damage such as vandalism to the external inlets. Also regularly check the internal outlets (landing valves) for wear and tear. If you think any part of the system has been tampered with you must report it to us as soon as possible.

What is a ‘Dry Riser’?
A dry riser is a system of pipes and valves used to enable the Fire Services to distribute water to various levels of tall buildings as part of the fire suppression system.
The dry riser pipe has a connection for the fire department at ground level which is usually recessed into the outside of the building and protected in a wired glass or lockable metal box.
The fire brigade can then pump water through this external point of the dry riser to allowing fire-fighters to connect hoses where required on each level of the building.
A dry riser is usually required wherever a floor is 18 metres above ground level or in low level buildings with over 60m distance from entrances.
