Step 2 · Tighten the Packing Nut
The first and often simplest fix is to gently tighten the packing nut. This is the larger nut located directly behind the faucet handle, where the valve stem enters the main body of the faucet. Use an adjustable wrench or slip-joint pliers to grip the packing nut securely. Turn the nut clockwise about 1/8 to 1/4 of a turn. This slight tightening can compress the existing packing material and stop a minor leak.
