Clean the Nozzles
To dislodge debris and mineral build-up:
Run water through the handshower.
Firmly rub your finger back and forth across the spray nozzles on
the handshower face.
If this fails to improve the performance of the handshower,
proceed to the "Clean the Screen Washer" section of this guide.
