FAQs
How does the sprinkler system work?
Residential and domestic sprinklers systems are permanently charged with water. The sprinkler heads are made up of a plug, a bulb/ fusible link, a deflector plate and a cover plate.
As the heat builds near to a sprinkler head it must reach 57°c+ before the cover plate falls away revealing the sprinkler head. As the temperature increases further to 68°c+, the bubble in the bulb expands breaking the glass or the solder melts on the fusible link (depending on the head type) releasing the plug and allowing the water to flow.
Sprinklers for this application are mechanically heat activated only so false alarms do not happen.
How long does installation take?
This depends on the size of a system. As a rough guide, a small 3-bedroom house (new build) would take 2 days. With installation, most of the work is undertaken at what we call ‘first fix’ which is installing the pipe and heads while we have access to the ceiling/floor voids.
Once all the pipework and heads are installed, we pressure test to ensure the integrity of the pipework. Much later in the project we return for second fix. This involves cover plates for the heads (after decoration is finished) and the system delivery equipment (mains connection/ pump and tank).
Lastly it’s commission time – we carry out a flow and pressure on the installed system to ensure it meets the design requirements.
Can you retrofit a fire sprinkler into homes?
Yes, but this will extend the installation time and may require additional work, such as redecoration, plastering, or boxing in, which would not be included in our scope.
How much does a sprinkler system cost?
The cost of installing a fire sprinkler system can vary based on the system type, risk category, installation method, and the number of sprinkler heads required. For example, a new-build 3-bedroom house may cost approximately £2,400 for a mains-fed system. Contact us for a free quotation.
