With the faucet fully reassembled, it's time to test your work. First, make sure the faucet handles are in the 'off' position. Slowly turn the water supply valves under the sink counter-clockwise to restore water flow. Turn them all the way to the open position. Now, closely inspect the faucet for any leaks around the handle base. Then, turn the repaired handle on and off several times, checking for smooth operation. Finally, turn the water off and watch the spout for several minutes to ensure the drip has stopped. If you see a small leak around the handle, use your wrench to tighten the packing nut by another 1/8 of a turn.
This guide provides step-by-step instructions for fixing a common drip in a two-handle faucet, which is typically caused by a worn-out rubber washer or O-ring. The process involves turning off the water, disassembling the handle that is causing the drip, replacing the internal seals, and reassembling the faucet.
No, specific brands are not strictly necessary. A basic set of screwdrivers (Phillips and flathead), an adjustable wrench, and a pair of pliers are usually sufficient for this project. The listed tools are recommendations for quality and ease of use, but common household tools will often suffice.
The most critical step is to completely shut off the water supply to the faucet before any disassembly. This usually involves turning the shut-off valves under the sink clockwise until tight, then confirming the water is off by turning on the faucet.
For a beginner, expect to spend about 30 to 60 minutes on this repair. The cost is typically very low, usually under $10-$20 for replacement washers, O-rings, and plumber's grease, as the main components are inexpensive.
If the drip persists, carefully inspect the valve seat for corrosion, nicks, or debris after removing the stem again. A damaged valve seat often needs to be cleaned or replaced, or the new washer/O-ring might not be seated properly or is the wrong size.
