How to Install a Two-Handle Shower Valve · Step 7 of 7
In this video
Turn on the water and test the new installation. Check for any leaks around the base of the spout. Pull the diverter knob to send water to the showerhead and ensure it functions correctly without leaking. Once the test is successful, apply a bead of tub and tile caulk around the top and sides of the tub spout where it meets the wall to prevent water from getting behind it. Smooth the caulk bead for a clean finish.
Goal: Verify the repair and finalize the installation.
- Leave a small uncaulked opening at the very bottom of the spout to allow any water that might get behind it to drain out into the tub.

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.
