Begin by shutting off the water supply to the faucet. Locate the hot and cold water shut-off valves, typically found inside the cabinet beneath the sink. Turn the handles a quarter turn to the closed position. Once the valves are closed, open the faucet handles on top of the sink to relieve any remaining pressure and drain the excess water from the lines.

Goal: Shut off water supply

  • Most modern shut-off valves only require a quarter turn to close. The handle should be perpendicular to the pipe when closed.

FAQs

Is this a truly beginner-friendly project, and can it really be done in two hours?

Yes, this is considered a beginner-level DIY project, especially for common leaks caused by worn washers or O-rings. While the estimated time is 2 hours, it can vary depending on your faucet type, the age of the faucet, and how easily components can be disassembled. Patience is key, but most first-timers find it manageable.

What tools are absolutely essential for this repair, and what if I don't have them all?

You'll definitely need a flathead screwdriver (like the Milwaukee 8 in. x 3/8 in. Slotted Flat Head) for the decorative cap, a Phillips head or another flathead for the handle screw, and an adjustable wrench for the packing nut on compression faucets. If you don't have the exact brand, ensure you have appropriate sizes to avoid stripping screws or nuts. Having a small cup for removed parts is also helpful.

Why is turning off the water supply so important, and how do I do it correctly?

Turning off the water supply is the most crucial first step to prevent flooding and allow safe work on the faucet. Locate the shut-off valves directly under the sink and turn them clockwise until they are tight. If your sink doesn't have individual shut-off valves, you'll need to turn off the main water supply to your house, usually found near your water meter or main pipe entry.

How do I know which specific O-rings and washers I need for my particular faucet model?

The most reliable method is to remove the old O-rings and washers and take them to a hardware store to match their size and material. If your faucet has a visible brand and model number, note it down, as this can help you find a specific repair kit. Many stores also sell universal O-ring and washer assortment kits which can be very useful for matching sizes.
