Sprinkler System Maintenance

Sprinkler Maintenance

Why Should Sprinklers be Serviced, Tested & Maintained?

It is important to ensure that every component within a sprinkler system operates correctly in the event of a fire. BS EN 12845:2015 stipulates the maintenance and servicing requirements to ensure fault free operation in the event of fire. If you have a sprinkler system which is not being maintained properly, your insurance may be invalid, and you may be committing a criminal offence under the Regulatory Reform (Fire Safety) Order 2005.
