Heating Pressure Loss Caused by Faulty Fitting Under Floor in Bangor, County Down
When a homeowner in Bangor, County Down noticed their heating system constantly losing pressure, they knew something wasn’t right. With no visible signs of water leaking above ground, they called B Keenan Plumbing & Heating to carry out a detailed investigation.
Hidden leaks can be some of the most frustrating problems for homeowners — especially when they occur beneath floors, where damage can build up quietly over time. That’s where our leak detection specialists come in.
The Problem: Mysterious Pressure Loss With No Visible Leak
The client reported their boiler dropping pressure daily, sometimes twice a day. They were topping it up repeatedly with no improvement.
There were:
- No damp patches on walls
- No water around radiators
- No visible pipework issues
This told us that the problem was likely below the surface, somewhere within the heating pipe network under the floor.
Our Leak Detection Process
Using professional-grade leak detection equipment — including thermal imaging and acoustic listening tools — we began systematically checking the heating circuits throughout the property.
Our diagnostics quickly pinpointed an area of unusual heat loss beneath the flooring in one room. On closer inspection, we confirmed the source:
A malfunctioned fitting on the heating pipework
Slowly leaking beneath the floor
Causing continuous pressure loss in the boiler
Thanks to the precision of our tools, the exact location was identified without lifting the entire floor — keeping disruption to a minimum.
The Repair
Once the area was isolated, we carefully removed a small section of flooring to access the pipework.
The faulty fitting was:
- Removed
- Replaced with a high-quality, durable component
- Pressure-tested
- System rebalanced and topped up
After refilling the system, the boiler held pressure perfectly — confirming a successful repair.
The Outcome
✔️ Fault detected quickly using advanced technology
✔️ Minimal floor disturbance
✔️ System pressure fully restored
✔️ Prevented long-term structural damage
✔️ Another happy customer in Bangor, County Down
This job highlights how common—but hidden—heating leaks can be, and why professional diagnostics are essential when pressure drops without explanation.
