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.

Low Water Pressure: A Practical Checklist
Pressure complaints are easier to diagnose when you first determine whether the problem affects one outlet, one zone or the whole property.
Water Pressure Changes During the Day
Pressure that varies by time can reflect supply conditions, demand, controls or system restrictions and should be measured before changes are specified.
Water Pressure Problems
Low or unstable pressure can result from supply conditions, restrictions, valves, filters, pumps, regulators, leaks or pipe sizing. The correct solution starts by identifying where pressure is being lost.
Whistling or Squealing Pipes
Whistling can be associated with restrictions, valves, flow velocity or specific fittings and should be traced to when and where it occurs.
