Full Answer

A single-lever faucet can be repaired by following these steps.

  1. Turn off the water
  2. Before beginning work on the faucet, turn off the water under the sink or at the main shutoff valve.

  3. Remove the handle
  4. Most single-lever faucet handles are attached to the full frame with a single screw, which can be removed with an Allen wrench. If the screw is stuck, spray the��screw with a penetrating oil daily��for a week, and then try to remove it. If that does not work, or if the screw is stripped, try drilling out the screw, which will ruin the handle but save the valve. If this does not work, wrap the cap below the handle with rubber tape and use pliers to grasp the cap and unscrew the whole assembly.��

  5. Replace faulty parts
  6. Some single-lever handles have an interior cartridge, as well as the cap, cam, packing, ball and rubber seats. Replace the cartridge, if there is one, as well as any O-rings or seals. A faucet repair kit typically includes all of the necessary parts to repair the faucet interior and repair the leak. If this doesn't solve the issue, replace the whole faucet.
