What the method does
Appropriate isolation can divide a large network into smaller questions. A suitable pressure test may help assess a suspect section or support checks after a repair. What the result means depends on the system and test conditions.
A section-level check, not a pinpoint location
The engineer considers the pipe condition, connected components and isolation arrangements before selecting a test. Temperature changes and imperfect isolation may affect readings. Where a section appears suspect, further methods can help investigate the physical route and possible source.
Where it may be useful
- Heating zones and underfloor loops
- Suitable hot and cold supplies
- Checks appropriate to a completed repair
What it cannot establish on its own
Pressure loss is not a map of the defect. A short test cannot demonstrate that every part of a whole system is free from future faults.
Before the visit
Make available any drawings and previous test results. Describe alterations or fragile components so the chosen test is appropriate for the installation.
An investigation, not an equipment checklist
The most useful method is the one that answers the next question about your plumbing. A visit may combine observations and tests, or find that another specialist is needed. We explain the findings and proposed access before the agreed repair. Our package is defined by its scope, not by using every instrument.
