The Mission: Inspect and repair the CHP system at a distribution centre for a leading supermarket in Rochdale. Address a radiator leak, replace faulty O-rings, and resolve additional issues.
Distribution centres are critical to retail operations, where every minute counts. For a place like Rochdale’s distribution hub, reliable power isn’t just important, it is essential to keeping the supply chain moving, shelves stocked, and customers happy. When issues arose with the CHP system, this supermarket needed a trusted partner to address the issues comprehensively. That’s where we came in. Canning’s approach is not limited to repair; we ensure systems are restored for long-term reliability.
The Solution
City FM brought us in to tackle a few big issues with the CHP system. Firstly, a radiator leak caused by an over-tightened O-ring plate, which compromised the seal. Then, there were snapped O-rings in the tray wash filters, compounding the faults. As if that wasn’t enough, we uncovered more problems with the pressurisation unit, which had a collapsed plastic receiver nut and a dodgy level switch. The system presented multiple failures, all of which were addressed by our team.
Initial Inspection & Repairs
We began with a detailed inspection of the radiator. After removing the front cover, we bypassed a faulty level switch and filled it with water to spot the problem. The issue was promptly identified: the O-ring plate had been over-tightened and wasn’t sealing properly. We swapped it out for a new one, restoring the correct seal. At the same time, we replaced the snapped O-rings in the tray wash filters, clearing up any potential leaks there too.

Tackling the Pressurisation Unit
During the refit, we noticed water leaking from the pressurisation unit. A closer look revealed a collapsed plastic receiver nut and a level switch hanging loose inside the tank, causing uncontrolled water leakage. We sorted these out by replacing the damaged components and reinforcing the unit, restoring it to watertight and reliable operation.
Final Testing & Clean-Up
Once everything was repaired, we refilled the system, opened the isolation valves, and ran a thorough test to check for leaks. As expected, no outlying leaks were found, marking the completion of our work. We made sure the site was left spotless, in line with our high standards and client expectations.
Conclusion
At Canning, we focus on delivering lasting solutions, not temporary fixes. For this Rochdale supermarket’s distribution centre, that meant tackling radiator leaks, replacing faulty parts, and reinforcing the pressurisation unit to ensure their operations could continue without disruption.
Thanks to our expertise and hands-on approach, the CHP system is now reliable, efficient, and ready for whatever comes next. This reflects our core commitment: keeping businesses powered and resilient, providing clients with confidence in their critical infrastructure
