Suspected leak in underfloor heating
Circuit information and the pattern of pressure loss help make an underfloor investigation more focused.
Gather what you know
A manifold photograph, circuit labels and a room layout can be useful. Share the installation history and any recent work. Do not alter valves or dismantle the manifold just to prepare for an enquiry.
Distinguish the circuit from the whole system
Falling pressure may relate to the underfloor loop or another part of the connected heating installation. Suitable sectional testing can help establish where further attention belongs.
Recognise the limits of imaging
A useful temperature pattern depends on operating conditions and floor construction. The warmest or coolest visible patch is not automatically the leak position. Findings need to be compared with the other tests.
Think about access and finishes
Necessary opening and plumbing repair are planned around the identified issue. Specialist floor finishes, drying and reinstatement need separate consideration and are not automatically included.

happening at home.
A damp patch. A moving meter. A boiler that keeps losing pressure. You don’t need to know where the leak is to make an enquiry.
