Client Location – Bangor, County Down
The Problem
A homeowner in Bangor contacted B Keenan Heating and Plumbing after repeatedly experiencing pressure loss in their central heating system. The system required frequent repressurising, but there were no obvious signs of leaks inside the property. No radiators were visibly leaking, and there was no apparent water damage, making the fault difficult to identify.
Unexplained pressure loss is a common indicator that professional leak detection is required, particularly where pipework may be concealed or located in less accessible areas.


Initial Leak Detection Assessment
Our engineers carried out a systematic heating system leak detection assessment, starting with checks of the boiler, pressure relief valve, radiators, and accessible pipework. As these components showed no faults, we focused our investigation on the system pipework.
Through targeted leak detection methods and close inspection, we identified a leaking section of pipe that was allowing water to escape slowly but consistently, causing the system pressure to drop.
The Cause of the Leak
The issue was traced to a damaged pipe within the heating system. Although the leak was not immediately obvious to the homeowner, even a small pipe leak can lead to ongoing pressure loss and reduced system efficiency over time.
Without accurate leak detection, this type of fault can go unnoticed until it results in larger leaks, water damage, or boiler failure.
The Leak Detection Solution
Once the leaking pipe was precisely located, the heating system was safely isolated. The damaged section of pipework was repaired and secured to prevent any future issues. The system was then repressurised and fully tested as part of our final leak detection checks.
These tests confirmed that the leak had been successfully resolved and that the heating system was holding pressure correctly.
The Outcome
- Successful leak detection of a hidden pipe fault
- Heating system pressure fully restored
- Permanent repair completed efficiently
- No further pressure loss
The client was relieved to have a clear diagnosis and a long-term solution to a problem that had been causing repeated inconvenience.
Key Takeaway: The Importance of Professional Leak Detection
Even small pipe leaks can cause significant issues within a heating system if left unresolved. Persistent pressure loss should never be ignored, as early leak detection can prevent more serious damage and costly repairs.
