The ball-type faucet is used by Delta, Peerless, and a few others. The
ball fits into the faucet body and is constructed with three holes (not
visible here)--a hot inlet, a cold inlet, and the outlet, which fills
the valve body with water that then flows to the spout or sprayer.
Depending on the position of the ball, each inlet hole is open, closed,
or somewhere in-between. The inlet holes are sealed to the ball with
valve seats, which are pressed tight against the ball with springs. If
water drips from the spout, replace the seats and springs. Or go ahead
and purchase an entire replacement kit and replace all or most of the
Step 1. Turn off the hot and cold water at the stop valves and open the
faucet to let any water drain from the pipes. Plug the sink drain with a
towel to avoid losing small parts. Pry off a red and blue hot/cold
button or a knob-handle button, if present, with a small screwdriver or
dull knife. Loosen the setscrew with the hex wrench on the ball faucet
tool. Now remove the handle.
Step 2. Wrap the jaws of your channel-type pliers with masking tape to
protect the faucet finish. Grasp the faceted or knurled edges of the
round ball cap with the pliers and twist to remove.
