Faucet leaking at the base or under the handle

You can fix this

Likely cause: a loose retainer ring under the handle

A wet paper towel means the handle is leaking and the water is only collecting at the base. Snugging the retainer ring under the handle often stops it.

Why this happens

Moen points out that a handle leak can puddle onto the base plate and look like a base leak. Pfister's fix for a kitchen faucet leaking at the handle is to remove the handle and dome cap and tighten the retainer ring with a crescent wrench. If tightening does not stop it, the seals on the cartridge are the next suspect.

How to fix it

  1. Shut off both stops under the sink and open the faucet to release pressure.
  2. Remove the handle and the dome cap beneath it.
  3. Tighten the retainer ring with a crescent wrench by turning it clockwise, as Pfister describes. Snug it; do not crank on it.
  4. Reassemble, reopen the stops, and repeat the paper-towel test.
  5. If the towel still gets wet, replace the cartridge, matched to your faucet.

The part that fixes it

Only needed if tightening the retainer ring does not stop the leak. Match the cartridge to your valve.

If this does not fix it, tell the plumber

  • The paper-towel test showed water coming from the handle.
  • Whether you tightened the retainer ring and what happened.
  • The faucet brand and model.
