Reassemble the faucet by reversing the steps above. First screw the valve stem back into the tap body, secure it with the nut, reattach the handle and decorative cap. Tighten the parts enough to ensure the faucet doesn't leak, but avoid overtightening. Turn the water back on gradually to prevent any damage to the pipes. Check the faucet for leaks once it’s fully assembled. If you see any drips, double check each part of the tap and tighten up the relevant screws and nuts.

Goal: Restore functionality

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.
