Replacing a 3-Handle Bathtub Faucet: A Step-by-Step Guide

Replacing a 3-handle bathtub faucet is a common plumbing project that many homeowners can tackle themselves. However, it is important to approach the task with caution and follow the right steps to ensure a successful and safe installation. This article provides a detailed guide to replacing a 3-handle bathtub faucet, outlining the necessary tools, materials, and procedures.

Step 1: Gather the Necessary Tools and Materials

Before starting the replacement process, it is crucial to gather all the necessary tools and materials. This will ensure a smooth and efficient operation. The following list includes the essential items:

Adjustable wrench
Channel-lock pliers
Phillips head screwdriver
Flathead screwdriver
Plumber's tape
New 3-handle bathtub faucet
New supply lines (if necessary)
New escutcheons (if necessary)
Safety glasses
Work gloves

Step 2: Turn Off the Water Supply

The first step in replacing a 3-handle bathtub faucet is to shut off the water supply. This prevents water from flowing through the faucet and causing leaks or damage during the replacement process. Locate the shut-off valves for the hot and cold water lines supplying the bathtub faucet. They are usually located under the sink or in the basement. Turn the valves completely clockwise to shut off the water supply.

Step 3: Drain the Remaining Water

After turning off the water supply, it is important to drain any remaining water from the faucet and pipes. This can be achieved by opening the faucet handles and allowing the water to flow out. If there is still water in the pipes, use a small drain pan to catch the water as it drains. This step is important to avoid exposure to water during the replacement process.

Step 4: Disconnect the Old Faucet

Once the water supply is shut off and the remaining water is drained, it is time to disconnect the old faucet. This involves loosening and removing the nuts and fittings connecting the faucet to the supply lines and the tub spout. Use the adjustable wrench and channel-lock pliers to loosen and remove the nuts. Be careful not to damage the surrounding pipes or fixtures.

Once the nuts are removed, you can lift the old faucet off of the tub spout and disconnect the supply lines. If the old faucet has any escutcheons, you can use a screwdriver to unscrew them from the deckplate.

Step 5: Install the New Faucet

With the old faucet removed, it is time to install the new faucet. This process involves connecting the new faucet to the supply lines and the tub spout. Follow the instructions that came with the new faucet carefully, as each model may have different features and installation steps. Begin by attaching the new supply lines to the new faucet. Use plumber's tape to wrap the threads of the supply lines to prevent leaks.

Next, attach the new faucet to the tub spout. Make sure the faucet is aligned correctly and tighten the connections securely, using the appropriate tools. After connecting the faucet to the supply lines and tub spout, check for leaks. Tighten any loose connections if necessary.

Step 6: Turn on the Water Supply

Once the new faucet is installed, it is time to turn on the water supply. Slowly open the shut-off valves to allow water to flow through the new faucet. Check for any leaks at the connections. If there are leaks, tighten the connections further or use plumber's tape to seal the connections.

Step 7: Test the Faucet

After turning on the water supply, test the new faucet to ensure it is functioning correctly. Turn the handles to the hot and cold positions to check the water flow and temperature. Make sure there are no leaks or drips coming from the faucet. If there are any issues, check your connections and tighten them as needed.
