Watching Peter kaye so here goes.
Seem to be doing a lot of copy/pasting today
Wet Rising and Dry rising mains are intended for use by the Fire Brigade or other trained personnel. They provide a readily available means of delivering considerable quantities of water to extinguish or to prevent the spread of fire.
Dry risers are vertical mains fitted into staircase enclosures or other suitable positions, with outlet valves on each floor and inlets fitted at ground level to enable the fire brigade to connect to the water supply.
Dry risers have to have fire engine access within 18m of the dry riser inlet box.
Wet risers are vertical mains kept permanently charged with water, either from a storage tank (via a booster pump) or direct from the town's main water supply. Before installing dry or wet rising mains the exact requirements of the local fire brigade must be ascertained.
Dry rising mains should be installed in buildings where any floor is at a height between 11 and 50 metres above ground level or where any floors are more than 10m below ground floor level. Any buildings over 50 metres will require a wet riser to be installed in accordance with BS9990/2006.
Site engineers will fabricate on site and make sure installation is done to design drawings. Any alterations will be dealt with as soon as they arise. Viva Fire Protection do not use sub-contractors, we have our own teams of engineers with well over 25 years combined experience within the industry. Therefore we can guarantee all projects undertaken will adhere to our highest standards. We also allocate a dedicated project manager and site supervisor to each project.
I woud say that the fire engine is forcing the water. This is taking me back about five years - had all the same problems!!
