Pressure testing can help assess a defined water-supply section when its boundaries and connected equipment are understood. A pressure change alone does not identify a precise leak location. Isolation, fixture conditions, temperature and the test arrangement can affect interpretation. Ask which part of the system is being evaluated and what a result would establish before authorizing a test.
The method must suit the existing system and be carried out with appropriate precautions. This is not a do-it-yourself instruction to add air or extra pressure to old plumbing. Request the conditions, findings and limitations in the assessment record. If a section appears to lose pressure, additional investigation may be needed before choosing where to open a floor or wall.
