Once again do not forget to apply some little amount of grease to maintain the smooth rotation all the times. Washers are responsible for keeping water from leaking; hence they should be lubricated well for effective functionality.

  1. Replace the Faucet arm and the ball socket.

This is done by gently pressing down the firmly, at the same time rotating it from one side to the other. This is to ensure that it fits in properly. Next, install another ball socket without forgetting the layout of the ball. For ease, ensure that the cylinder is standing upright in the beginning.
