Clean the Spray Holes
NOTE: The appearance of your handshower may differ from the
illustration. The instructions still apply.
To dislodge debris and mineral build-up:
Run water through the handshower.
Firmly rub your finger back and forth across the spray holes in
the handshower face.
If this procedure fails to improve the performance of the
handshower, proceed to the "Clean the Handshower Screen
Washer" section of this guide.
