Understanding Pressure Testing in Leak Detection
Leak testing, including pressure testing, also known as hydrostatic testing when using water, involves pressurising the pipework to 1.1 times its normal working pressure in England and Wales, according to BS EN 806 specifications. Regulations require leak testing at 1.5 times the working pressure. Our method employs a safe mix of 95% Nitrogen and 5% Hydrogen, leveraging Hydrogen’s small molecular size and traceability, combined with the safety of non-flammable Nitrogen. Conducting pressure tests is a crucial component of ensuring the integrity of piping systems, aligning with BS EN 806 specifications.

Our team is skilled in various leak detection technologies, ensuring a high success rate.
Pressure testing is a precise diagnostic technique used to identify leaks in water systems, including properties, hot water pipes, underfloor heating, and central heating circuits. By pressurizing the system and monitoring pressure drops, this non-invasive method accurately detects hidden or inaccessible leaks, enabling targeted repairs and preventing further damage.
0800 Homefix’s pressure testing can be applied to a wide range of systems:
Our thermal imaging services can detect leaks in several scenarios:
From apartments to large buildings, we ensure all plumbing is secure.
Including swimming pool filtration, irrigation systems, and low pressure testing, where precision is critical.
0800 Homefix’s pressure testing services are utilised within numerous industries, showcasing the broad applicability of their expertise.
Process and Timeframe
The typical pressure test follows a specific procedure how to test and lasts for 60 minutes. If no pressure drop is detected, it confirms the absence of leaks. Maintaining specific test pressures throughout the test is crucial for detecting leaks. However, the complete process includes additional time for setting up and concluding the test, ensuring that every step is performed meticulously.

Locating the Leak
While pressure testing pinpoints the possibility of a leak, it does not specify the location. For this, we employ tracer gas sensors or acoustic listening devices to detect escaping gas, accurately revealing the leak’s exact location. The primary purpose of using these technologies is to identify defects causing leaks. A ‘pressure change’ detected by these devices is a key indicator of the presence of a leak, allowing for precise identification and assessment of the flaws within the system.

Happy Customers

Camilla Smith
Great customer service From the initial telephone conversation with Rachel, I felt in safe hands with 0800 Homefix. Rachel arranged for an engineer to inspect the problems I was having with my faulty boiler, Rachel arranged for an engineer to come out that day which was brilliant. The customer service was brilliant from the start to finish, I highly recommend 0800 Homefix. Thank you again.

Customer in Wokingham
Following on from a new central heating system installed by 0800 Homefix there was a lot of dust throughout the property, it was a huge job in fairness we never had central heating before as it was warm air units so the engineers were working in every room running pipes and hanging radiators. 0800 Homefix kindly facilitated a professional deep clean following on from the works at no extra cost. Very thoughtful and professional. The house is now spotless. Would highly recommend.

Customer in Farnham
Leak fixed I called out we fix to investigate a leak that was present in my kitchen. I was reluctant to do so due to the ongoing matters with COVID-19. However, the engineer that turned up to fix the leak was equipped with a face mask, gloves and shoe covers. He also made sure to keep 2 metres distance away from me and my wife at all times. He fixed the leak and kept everything tidy and clean throughout. Would not think twice about recommending!
