Solder the Pipe and Fitting — Assemble and Solder New Valve
Part of project
How to Install a Two-Handle Shower Valve · Step 5 of 7
In this video
With the components fluxed and assembled, the plumber proceeds to solder the joint. The pipe assembly is held securely with a pair of pliers. A propane torch is used to heat the fitting evenly. Once the copper is hot enough, which is indicated by the flux smoking and bubbling, lead-free solder is touched to the joint. The heat from the copper melts the solder, and capillary action pulls it into the gap between the pipe and fitting, creating a permanent, watertight seal.
Goal: Create a permanent, watertight joint
- Always wear safety glasses when soldering. The torch flame and hot solder can cause serious injury.
- Heat the fitting, not the solder directly. The fitting should be hot enough to melt the solder on contact. This ensures the solder is drawn into the joint properly.

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.
