How the method contributes
Suitable isolation can turn a property-wide problem into a more focused question about one circuit. Pressure behaviour under appropriate conditions helps inform that assessment. After repair, suitable testing also contributes to checking the affected plumbing. The test is selected for the actual system, its condition and its access arrangements.
Where it can be useful
- Heating circuits and floor loops
- Concealed hot and cold supplies
- Appropriate checks after repair
Its practical limitations
Part of an investigation, not a guess
The engineer chooses the methods that can usefully test a possibility. Results are compared with the property layout and symptoms before access is proposed. See the full investigation and repair process.
