Commercial Pressurisation Unit Service

What this service covers

A planned service focuses on performance, reliability and records, with clear findings and practical recommendations. Typical coverage includes:

• Visual inspection for leaks, corrosion, abnormal noise and vibration
• Checking pump operation, duty and standby changeover (where fitted)
• Verifying set pressures, cut in and cut out points, and top up function
• Inspecting break tank and water level controls (if applicable)
• Testing alarms, interlocks and basic control functions
• Checking pressure gauges and sensors for accuracy and condition
• Inspecting valves, strainers and backflow protection on the fill line
• Identifying parts at end of life and advising on remedial works
• Service report for your maintenance file, with actions prioritised

When this service is most useful

This service suits offices, retail units, managed buildings and plant rooms with sealed systems where pressure stability matters. It is particularly relevant if you have recurring low pressure alarms, unexplained top ups, frequent call outs, or recent changes to the system. It also works well as part of a PPM schedule to reduce downtime and protect plant.

What happens on the day

You agree access, site rules and any system constraints in advance, including whether a shut down is needed. The engineer isolates safely, checks the unit and associated pipework, then tests operation and settings against system requirements. You receive a written summary of results and any follow up actions, with clear next steps if repairs or parts are required.

Ongoing value and follow up

If issues are found, you can prioritise remedials to match risk and operational impact, from minor adjustments to component replacement or full unit upgrade. For ongoing compliance and reliability, servicing can be scheduled at agreed intervals with consistent reporting, helping you build a clear maintenance record and reduce unplanned disruption.
