Define the pattern
Note exactly which fixtures are affected, when the symptom occurs and whether it changes with use elsewhere in the property. The pattern helps distinguish a local fitting problem from a wider supply, waste or drainage issue.
Avoid replacing parts by guesswork
Visible symptoms can have more than one cause. A useful first inspection checks the simplest accessible possibilities and gathers evidence before opening finishes or replacing major components unnecessarily.
What to send on WhatsApp
Send the property location, a short description of what happens, when it happens, which other fixtures are normal and clear photographs or a short video where useful. Mention any previous repair to the same area because recurrence changes the investigation.
