9. Replacing the Non-Retraction Valve
A water Non-Retraction Valve is integrated in the Coupling Joint (the product below), which shuts off the water retraction directly at the handpiece head
to prevent fluids infiltrating the water line. If water is beginning to leak from the handpiece, replace the non-retraction valve.
