Domestic & Residential Sprinkler System Installation
A typical fire sprinkler installation will use CPVC pipe work and concealed fire sprinkler heads. The pipe work and sprinkler heads are installed in accordance with the design drawings. The pipe work is secured to the structure and glued together with solvent cement.
It is preferable for the fire sprinkler heads to be fitted as part of the first fix, to allow for pressure testing of the whole system, prior to it being closed up by ceilings/floors. Each sprinkler head is fitted accurately to ensure the sprinkler cover plate sits flush to the finished ceiling.
The above shows a sprinkler head fitted using pipe work to drop the head to the desired level. This is the most desired option and can be used to fit sprinklers in a ceiling void from 150mm and upwards.
The above is a method we would use when we have a limited ceiling void. The minimum void required is 105mm.
Sprinkler System pressure tested and ready for ceilings to be installed. (Above)
The fire sprinkler heads are left with a plastic rubber protective cap. The centre of this cover has a point which will mark the plasterboard to allow the correct size hole to be cut.
Ceilings installed and cover plate fitted (above)
Once the ceilings are fitted and decoration complete, the protective covers will be removed and the sprinkler head decorative cover plates are fitted.
