TL;DR: To fix a leaky faucet, turn off the water supply, disassemble the handle, replace the worn washer or cartridge, and reassemble the components. This simple repair saves money and prevents water waste.
A dripping faucet is more than just a minor annoyance; it can waste gallons of water daily and increase your utility bills significantly. Fortunately, most leaks are caused by simple wear and tear on internal components like washers, O-rings, or cartridges. By following a systematic approach, you can restore your faucet to perfect working order without calling a professional plumber. This guide will walk you through the essential steps to diagnose and repair common faucet leaks effectively.

Prepare Your Workspace
Before touching any tools, ensure you have the necessary items ready. You will need an adjustable wrench, screwdrivers (both flathead and Phillips), pliers, and a replacement kit specific to your faucet type. Most hardware stores carry universal repair kits, but it is best to bring an old washer or cartridge to the store for an exact match. Clear the area under the sink and place a towel or bucket to catch any residual water. This preparation prevents messes and ensures you do not lose small parts down the drain.
Shut Off the Water
Safety and cleanliness are paramount. Locate the shut-off valves under the sink and turn them clockwise until they are tight. If there are no individual valves, you may need to shut off the main water supply to your house. Once the water is off, open the faucet to release any remaining pressure and water in the lines. This step is crucial to prevent spraying water when you disassemble the faucet components.
Disassemble the Faucet
Start by removing the decorative cap on the faucet handle, usually found on top. Use a small screwdriver or knife to gently pry it off. Underneath, you will find a screw securing the handle. Remove this screw and lift the handle off. If the handle is stuck, use pliers gently to wiggle it free. Depending on your faucet type, you may need to remove a retaining nut or clip next. Keep track of every screw and part, laying them out in order on your towel. This organization makes reassembly much easier and less confusing.
Replace Faulty Parts
Inspect the internal components for signs of wear. In compression faucets, look for the rubber washer at the bottom of the stem. If it is cracked, flattened, or eroded, replace it with a new one. For cartridge or ball-type faucets, inspect the O-rings and seals. Lubricate new O-rings with plumber’s grease before installing them. Ensure the new parts fit snugly and correctly. Do not force any components, as this can damage the faucet body. Take photos during disassembly to help guide you during reassembly.
Reassemble and Test
Reverse the disassembly steps to put everything back together. Tighten all screws and nuts securely but do not overtighten, as this can strip threads or crack plastic parts. Once reassembled, turn the water supply back on slowly. Check for leaks around the base and handle. If water drips, tighten connections slightly. If the leak persists, recheck your seals and ensure they are seated properly. A well-sealed faucet should operate smoothly without any dripping.
