Clean the Spray Holes
To dislodge debris and mineral build-up:
Run water through the showerhead.
Firmly rub your finger back and forth across the spray holes in
the showerhead face.
If this procedure fails to improve the performance of the
showerhead, proceed to the "Clean the Screen Washer" section of
this guide.
