Record when it happens
Note whether the symptom is constant or intermittent, which fixtures are affected and whether it changes when other water outlets are used. Timing and distribution often provide more useful evidence than the symptom alone.
Check the local-versus-system pattern
Compare nearby fixtures where it is safe and practical. A fault affecting one outlet usually follows a different investigation path from a symptom affecting an entire bathroom, hot-water system or property.
What a plumber needs to know
Send the location, a concise symptom description, any recent work to the same area and clear photos or video where useful. Avoid dismantling pressurised fittings or concealed services simply to obtain more information.
