Replacing a two-handle bathtub faucet is a practical task that improves the look and function of your bathroom.
Begin by gathering the necessary tools and materials.
Make sure the water supply to the bathtub is turned off.
Then proceed to disassemble the existing faucet. Remove the handles and escutcheon plates, take out the old cartridge or stem, and replace the O-rings if they are worn.
Install the new faucet assembly with care to prevent leaks.
After installation, turn the water supply back on and test the new faucet to confirm it is working correctly.
This guide outlines the steps to replace a two-handle bathtub faucet.
Gather Your Tools and Materials
Before starting the replacement of a two-handle bathtub faucet, gather all necessary tools and materials. Having the right tools will help the process go smoothly and comply with plumbing codes, reducing the chance of delays or problems. Ensure the new faucet handles are compatible with your bathtub. You will need an allen wrench and a flat-head screwdriver to remove the old faucet and install the new one, as these tools are used for loosening and tightening screws on the handles and trim plate.
Check the water supply line for wear or damage. If it needs replacement, have a new one ready. Choose a replacement faucet that fits your bathtub's specifications and meets local plumbing codes for safety and performance.
You may also need new plumbers' putty or tape to create watertight seals and prevent leaks. Consider buying a replacement faucet from a plumbing supply center for higher quality and durability.
Prepare all tools and materials before starting. This preparation will help you confidently remove the old faucet, disconnect the supply line, and install the new faucet in compliance with plumbing standards.
Shut Off Water Supply
Before replacing your bathtub faucet, turn off the main water supply to prevent flooding. The shut-off valve is usually located in the basement, garage, or outside near the water meter. Rotate it clockwise to stop the water flow.
After shutting off the water, open the faucet to drain any remaining water from the pipes, then close the handles again. Place a bucket or towel beneath the faucet to catch drips as you remove the faucet parts.
If there's an access panel for the faucet's plumbing, use it. If not, create an access point if necessary. In cold climates, insulate any exposed pipes to prevent freezing and potential damage.
Remove Existing Faucet Handles
After turning off the water and preparing the area, begin by removing the faucet handles from the bathtub. Pry off the handle's plastic cover to reveal the screw beneath. Use a screwdriver to remove this screw and free the handle from the stem. If the handle is stuck due to mineral buildup or corrosion, use a faucet handle puller to remove it without damage.
Next, focus on the hex nut that holds the stem in place. Use a socket wrench to turn it counterclockwise and remove the nut. Keep all parts organized for reference or reassembly if needed.
If there's a second handle, repeat these steps. With both handles removed, you can move on to replacing the faucet body.
Install New Faucet Assembly
After removing the old faucet handles, proceed to install the new faucet assembly by placing it in the openings on the bathtub. Insert the new stem into the valve socket, ensuring proper alignment to avoid leaks. Check the valve sockets' seats for wear and replace if needed to ensure a tight seal and prevent leaks.
Attach the new tub spout to the copper pipe from the wall. If soldering is necessary, consider hiring a professional if you lack plumbing experience, as it creates a strong, leak-proof connection. For a screw-on spout, use thread sealant or plumbers' tape on the copper pipe threads before screwing on the spout clockwise, avoiding overtightening which can damage threads.
Affix the faucet handles to the new stems by sliding them on and securing with the set screw, turning it clockwise without overtightening to avoid damaging the screw or handle.
After installation, turn on the water supply and check for any leaks, addressing them immediately to prevent water damage. With the correct parts and attention to detail, the new faucet should function well and enhance the appearance of your bathtub.
Test and Finish Up
After installing the new faucet handles, test them to ensure proper function and check for leaks. Clear the area of any tools or materials, and turn on the bathroom's main water supply. Observe the faucet handles and spout for water flow and examine all connections for leaks.
Leaks may occur with new installations. If you find any, shut off the water and tighten fittings or apply plumber's tape as needed. Reassemble the faucet if leaks continue and check seals or components.
Once adjusted, turn the water back on and retest the faucet. Confirm that the new faucet works correctly and does not leak. Compare it to the previous one to ensure improved performance and appearance.
After testing, clean the workspace and discard debris. Insulate pipes if necessary. Optionally, install a leak detection device to monitor for future leaks.
This completes the faucet replacement.
