| Cartridge
faucets often are the single-lever faucets you'll find
on kitchen sinks. Leaks usually are caused by worn-out
cartridges and old seals. On cartridge-type faucets,
those rubber seals are called O-rings. The surest way
to repair a cartridge-type faucet is to completely
replace the cartridge and the O-rings. When you buy a replacement
cartridge, look for repair kits that include the correct
O-rings. |

 First, turn
off the water supply at the shutoff valves. Then, use the
tip of a screwdriver to pry off the index cap on the top
of the faucet. Once it's off, remove the handle screw
underneath the cap. |
 |
| |
|
 Remove the
faucet handle by lifting it up and then tilting it
backwards slightly. |
 |
| |
|
 Remove the
threaded retaining ring with slip joint pliers. Remove any
retaining clip holding the cartridge in place. |
 |
| |
|
 Grip the top
of the cartridge with the pliers. Pull straight up to
remove the cartridge. Install the replacement cartridge so
that the tab on the new cartridge faces forward. |
 |
| |
|
 To expose
the O-rings, remove the spout by pulling it up and
twisting slightly. Cut off the old O-rings with a utility
knife. Coat the new O-rings with heatproof grease and
install them. |
 |
| |
|
 Reattach the
spout. Screw the retaining ring onto the faucet, and
tighten the ring with the slip joint pliers. Attach the
handle, the handle screw, and the index cap. Turn the
water back on. |
