Turn off the hot and cold water supply valves under the sink. These are usually located inside the vanity cabinet. Turn the valves clockwise to shut them off. If the valves are ball valves, it will only take a quarter turn to close them. Once turned off, open the hot and cold taps on the faucet to relieve any remaining pressure.

FAQs

What's the very first thing I need to do to safely start this faucet repair?

Always begin by turning off both the hot and cold water supply valves located under your sink. After that, briefly turn on the faucet to release any residual water pressure and ensure the water flow has completely stopped before proceeding.

The guide lists specific Milwaukee and HDX screwdrivers. Do I need these exact brands, or will generic tools work?

While specific brands are mentioned, the key is to have the correct *type* and *size* of screwdrivers for your faucet. You'll need a flat-head screwdriver for prying the decorative cap and another appropriate screwdriver (often flat-head or Phillips) to remove the handle screw. An adjustable wrench is essential for the packing nut.

What if I can't get the decorative cap off, or the handle screw is stripped or stuck?

Avoid forcing stuck parts, as this can cause damage. For a stubborn cap, try a thin plastic pry tool to prevent scratches. If a screw is stuck, a penetrating oil might help loosen it, or you may need a screw extractor if it's stripped beyond simple removal.

How much should I expect to spend on parts for this DIY faucet repair, and how long does it usually take?

Most faucet repair kits, which include new O-rings and seat washers, are very inexpensive, typically costing under $10-$20. The project is estimated to take around 60 minutes for beginners, potentially less if you're experienced or if the components are easily accessible.
