Turning Off the Water Supply

Gathering the Tools and Materials

Before you begin, make sure you have all the necessary tools and materials ready. You’ll need an adjustable wrench, a pipe wrench, a screwdriver, plumber’s tape, a new faucet, and safety goggles. Having everything at hand will save you time and frustration as you work through the steps.

Turning Off the Water Supply

If you’re planning to do any plumbing work, it’s important to know how to turn off the water supply to the affected area. For example, if you’re fixing an outdoor faucet too low to the ground, you’ll need to locate the shut-off valves near the affected area. Turn them clockwise until they’re fully closed to prevent any water from flowing through the pipes. Don’t forget to turn on the faucet to drain any remaining water in the pipes for safety reasons.

Preparing the New Faucet

Removing the Old Faucet

Now comes the hands-on part. Remove any decorative handles or covers to access the faucet’s inner workings. Use your screwdriver and wrenches to carefully disconnect the water supply lines. Next, use the pipe wrench to loosen and remove the old faucet from the wall. Be prepared for some resistance, as faucets can become corroded over time.

Preparing the New Faucet

Before you install the new faucet, wrap the threads of the water pipe with plumber’s tape. This will help create a watertight seal and prevent leaks. Follow the manufacturer’s instructions to assemble any components of the new faucet that need to be put together before installation.

Installing the New Faucet

Position the new faucet over the water pipes and hand-tighten the connectors. Once they’re secure, use your wrenches to tighten them a bit further. Be careful not to overtighten, as this could damage the new faucet or the pipes. Reconnect the water supply lines and ensure everything is properly aligned.

Testing and Checking for Leaks

With the new faucet in place, it’s time to turn the water supply back on and test your handiwork. Check for any leaks around the connections and handles. If you notice any leaks, tighten the connections slightly until they stop. Don’t forget to reattach any decorative covers or handles that you removed earlier.


Replacing a bathtub faucet might seem like a daunting task, but with the right tools and a step-by-step approach, you can accomplish it successfully. In addition to upgrading your bathroom’s aesthetics, replacing a bathtub faucet and learning how to unclog a bathtub drain can also spare you the annoyance of dealing with a leaky faucet and a clogged drain.
