Why the water is not flowing normally
A buildup or clog at the showerhead can affect the flow. A damaged head, valve problem or concern in the supply piping may also need attention. Checking the fixture and its connections helps distinguish a showerhead issue from a problem that a new head would not solve.
Tell us whether the water has become weaker, whether the control is difficult to use and whether other fixtures are affected. Those details help focus the inspection without treating reduced flow as a diagnosis by itself.
