Test the Repair — Secure Valve and Test for Leaks

How to Install a Two-Handle Shower Valve · Step 6 of 7
In this video
Before the final assembly, test the repair. Re-install the bonnet nut, then the outer sleeve, and temporarily place the handle on the stem to close the valve. Go to the access panel and turn both water supply valves back on. Use a flashlight to check for any leaks around the plumbing in the access panel and around the valve in the shower. Turn the shower on to verify that the hot and cold water now correspond correctly to the handle positions. Let it run for 5-10 minutes to ensure no leaks develop under pressure.
Goal: Verify the repair is successful and leak-free.
- Running the water for an extended period is the best way to ensure there are no slow drips or leaks.

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.
