Find the useful boundary between circuits
Earlier boiler findings, radiator observations and the pattern of pressure loss help guide the starting point. Where possible, isolation and pressure testing narrow the enquiry to a section of the heating system. Suitable thermal or tracer work then supports tracing before a repair opening is discussed.
When this investigation may help
- Recurring loss of heating pressure
- Damp that changes when the heating runs
- A suspected leak under a heated floor
- Hidden pipework remaining suspect after earlier checks
A method suited to the evidence
Narrowing the enquiry to the section of pipework that needs attention. A pressure change does not pinpoint an opening location. The engineer selects suitable conditions for the actual system.
Depending on the property, other appropriate methods may complement the investigation. Read about pressure testing and isolation or compare the methods.
Before the visit
Let us know about previous boiler visits, heating zones and recent alterations. Ask for preparation instructions rather than repeatedly topping up solely for the visit.
Boiler servicing, gas work and unrelated appliance components are outside this plumbing package. Some pressure problems require an appropriately qualified heating engineer first.
From finding the leak to repairing it
The residential package connects the investigation with necessary access, plumbing repair and suitable post-repair checks. Parts and materials are included for the agreed job. The report records the relevant findings, and the plumbing repair has a 12-month workmanship warranty.
