Pressure Test System — Secure Valve and Test for Leaks
Part of project
How to Install a Two-Handle Shower Valve · Step 6 of 7
In this video
Before closing the wall, it is critical to test the new plumbing for leaks. Temporarily cap the shower riser port. Attach a pressure testing gauge, such as a SharkBite push-to-connect hose adapter with a gauge, to the end of the copper tub spout pipe. Turn on the water supply at the new shut-off valves and pressurize the system. Check all solder joints and crimp connections for any signs of leaks. Leave the system under pressure for a period of time (as required by local code) to ensure it is watertight.
Goal: Plumbing Pipes Repair (Leaking)
- Never skip pressure testing. Finding and fixing a leak after the wall is finished is significantly more difficult and expensive.

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.
