Preston Case Study
What we did
Each tower is fitted with dedicated sprinkler risers and test valves on each floor. As part of the service, our engineers conducted a series of functional and safety inspections, including:
-
Flow Testing: Flow tests were carried out on all floors across both buildings, with flow rates averaging between 150 and 200 litres per minute. The fire alarm system successfully activated during each test, confirming reliable operation in the event of sprinkler activation.
-
Visual Inspections: Our team completed thorough inspections in every apartment, checking that all sprinkler heads were clear, unobstructed and free from corrosion, paint or physical damage. During this process, two sprinkler covers were found to be painted over, and one sprinkler head was identified as incorrectly positioned and requiring adjustment.
-
Pump set and associated plant: The pumps and water tank were also inspected to identify any signs of wear, leaks or potential faults that could impact the system performance.
Challenges and next steps
During the service, we identified some issues requiring follow-up…
-
Two sprinkler covers had been painted over and require replacement.
-
One sprinkler head was installed at incorrect heights and needs to be lowed.
We’ve issued a quote for these remedial works and will return shortly to carry out the necessary adjustments and replacements to ensure the system remains fully compliant and operational.
The Results
The service confirmed that the sprinkler system is largely functional; however, the identified issues mean that not all areas are currently receiving full protection. Once the remedial actions are completed, the system will meet full compliance with BS 9251 standards and provide fire protection throughout both tower blocks.
This highlights the importance of routine servicing in identifying and addressing issues early, ensuring the ongoing reliability and effectiveness of fire sprinkler systems for residents, building management and emergency services.
