Make the instruction clear
A useful leak investigation begins with the information already held by the site. Plant-room access, schematics and knowledge of past repairs can make the test plan more specific.
What helps before the appointment
Explain isolation boundaries, sensitive equipment, permitted working windows and any site induction requirements. Agree who can authorise interruption before the appointment.
From investigation to an agreed repair
Suitable checks and specialist methods help establish the evidence. The proposed access is explained before the agreed plumbing work is performed. Appropriate testing and a written report help make the outcome understandable to the people coordinating the property.

Complex or shared systems need an individual scope and quotation. Reporting requirements should be discussed at the outset.
Coordinate the stages after repair
Restoring floor coverings, plaster, decoration and other finishes is separate from the plumbing package. Drying may also need specialist attention. Keep the report available for anyone arranging those follow-on stages.
