Access and Remove the Old Valve Body — Remove Old Shower Valve
Part of project
How to Install a Two-Handle Shower Valve · Step 3 of 7
In this video
To remove the old valve, you will need to access it from behind the wall. This may involve cutting an access panel in the drywall on the other side of the shower wall. Once you have access, use two pipe wrenches or adjustable wrenches—one to hold the water pipe steady and the other to loosen the union nuts connecting the hot and cold water lines to the valve body. After disconnecting the water lines and the pipes leading to the shower head and tub spout, the old valve can be removed from the wall.
Goal: Bathtub Faucet Removal
- Use two wrenches working in opposite directions to avoid twisting and damaging the water pipes inside the wall.
Used in this video
- Pipe wrench (brand: N/A, Wrench Type: Pipe wrench) — Gripping and turning the large union nuts to disconnect the valve.
- Utility knife (brand: N/A, Utility_Knife_Blade_Type: Retractable) · optional — Cutting an access panel in the drywall behind the shower.

FAQs
What are the most critical skills and tools required for this project, especially for a beginner?
The most critical skill is copper pipe soldering, as the new valve needs to be securely joined. Essential tools include a pipe cutter (like the AUTOCUT 1/2 in. Copper Pipe Tubing Cutter), a soldering torch kit, flux, solder, and safety glasses (HDX Indoor Safety Glasses). Practice soldering on scrap pipe if you're new to it.
How can I ensure I don't cause water damage or other issues during installation?
Always shut off the main water supply to your house before starting any plumbing work. After soldering, pressurize the system and carefully inspect all new connections for leaks before closing up the wall. Use Kleenex Paper Towels to dab around joints and confirm they are completely dry.
What's a realistic timeframe and difficulty level I should expect for this shower valve replacement?
This project is rated intermediate due to the necessary soldering and gaining access to the plumbing within the wall. For an experienced DIYer, it might take 4-6 hours, but beginners should budget a full day (8+ hours) to account for learning, careful work, and potential troubleshooting.
Are there alternatives to soldering the new shower valve if I'm not comfortable with a torch?
Yes, you can use push-to-connect (e.g., SharkBite) or PEX crimp fittings as alternatives to soldering. These methods require different tools like a PEX crimper or just the specific fittings themselves. While often quicker, they can be more expensive than traditional copper soldering and may result in a bulkier installation.
