Description of the leak: With this leak, water will leak from the area where the faucet base touches the escutcheon plate or countertop. This leak could be a temporary drip or a continuous leak.

Causes of the Leak

  • Temporary leak: This leak lasts while the faucet is running.  Dirt or debris have collected on the seals/o-rings/bearings which prevents the seals from making the faucet water-tight. The seals/o-rings/bearings are located in the faucet body. 
  • Continuous leak: This is characterized by a constant leak that occurs after the faucet is turned off. Dirt and debris have collected in the valve/cartridge which prevents the valve from properly controlling the flow of water.  The valve/cartridge is located under the handle. In some faucets, the check valve/spacer has also worn out. The check valve is located under the valve in the faucet body. 

Solution for the Leak

Temporary leak solution: Replace the seals/o-rings/bearing to return to water-tight faucet operation. The part number for the replacement seals will vary depending on the faucet model number.

Continuous leak solution: The issues should be resolved by replacing the valve/cartridge and/or the check valve/spacer(depending on your faucet model). The part number of the replacement valve and check valve will vary depending on the faucet model number.
