Pump Expert Shares Top Summer Cooling System Tips To Keep Public Sector Facilities Operational This Summer
The UK is heading towards what is predicted to be another record-breaking summer1 with the start of May already confirmed as the hottest on record.
, Ensuring essential cooling systems operate at peak efficiency is vital for public sector organisations across the UK.
Prolonged heatwaves and higher temperatures expected for summer 2025 will place increased strain on HVAC and pump systems - vital infrastructure that can be overlooked after months of minimal use during winter. In public sector buildings, a failure of these systems can lead to serious disruptions, health risks or closures.
John Calder, technical director at Dura Pump, has shared his expert advice drawn from over 15 years of experience to help facilities teams stay one step ahead and avoid costly downtime this summer.
Run Your Pumps Early To Avoid Surprises
In an ideal world, maintenance would be carried out regularly throughout the year, as regular inspections help identify leaks, worn components and loose connections early. Routine tasks such as filter replacements and system flushing are essential for keeping pumps in top condition and prepared for the increased demands of summer.
“It’s not uncommon for pumps to seize after a period of
inactivity.” John explains: “Running your system early in the season helps uncover these issues in a controlled, low-risk environment, giving you time to schedule routine maintenance tasks before they become urgent, and harder to manage at a time when the pumps are needed the most.”
After months of inactivity, cooling pumps can seize or
malfunction when first reactivated, often due to hardened seals, blocked impellers or corrosion. Simply switching your system on when the hot weather hits can reveal hidden faults during peak time.

“Cooling systems rely on a consistent pressure range to function properly”, John adds, “A failing or incorrectly configured pressurisation unit can lead to airlocks or system failure, both of which reduce cooling efficiency and increase wear.”
Installing pressure sensors can also help monitor performance continuously.
Pressure sensors function as a protector,
contributing to improving their system performance, extending the pump’s lifespan and reducing energy. With alerts set for pressure fluctuations, facilities teams can catch issues early and intervene before they escalate.
Check System Pressurisation
Getting the pressure right in your cooling system is more than a box-ticking exercise - It is critical to performance and safety. If the pressure is too low, the system may stop working entirely. If the pressure is too high, this may damage pipes, cause excessive water usage, leaks, and shorter appliance life spans. It’s a simple check, but one of the most important on your summer maintenance to-do list.
