Soldering Copper Pipes — Connect Water Supply Lines

How to Rough-In a Shower Valve: A Step-by-Step DIY Guide · Step 3 of 4
In this video
Measure, cut, and dry-fit all copper pipes and fittings for the hot and cold water inlets, as well as the outlets for the main shower head and the handheld wand. Once fitted, use a torch, flux, and lead-free solder to permanently join all the copper components. Heat each joint evenly and apply solder, allowing it to be drawn into the joint to create a watertight seal. This includes soldering the pipes directly to the valve body and creating the necessary pipe runs.
Goal: Connect plumbing lines
- Soldering creates high heat and fumes. Work in a well-ventilated area and use proper safety gear, including gloves and safety glasses. Keep a fire extinguisher nearby.

FAQs
How difficult is roughing-in a shower valve for a beginner, and what's the typical time commitment?
While rated "beginner," this project requires careful attention to detail, especially with water connections and leak prevention. For a beginner, expect it to take a full afternoon or even a day, accounting for preparation, learning, and thorough leak testing. Rushing can lead to costly mistakes.
What are the most important safety precautions to take during this plumbing project, especially regarding water and tools like a torch?
Always shut off the main water supply to the house before starting to prevent flooding and water damage. When using a Bernzomatic Pen Torch for soldering, ensure you have proper ventilation, a fire extinguisher nearby, and wear appropriate safety glasses and gloves to prevent burns. Always double-check electrical safety if working near any electrical outlets.
How do I ensure the shower valve is installed at the correct height and depth for comfortable use and the finished wall?
Always follow the shower valve manufacturer's instructions for rough-in dimensions, especially for the recommended height of the valve. Use a level to ensure the blocking and valve are perfectly plumb and level. Remember to account for the thickness of your finished wall material (e.g., tile and backer board) when setting the valve depth to ensure the trim fits flush and the handle isn't too recessed or protruding.
What steps should I take immediately if I discover a leak during the final water pressure test?
If you find a leak, immediately turn off the main water supply to the house again. Identify the exact source of the leak; it's often a poorly soldered joint or a loose threaded fitting. If it's a solder joint, drain the pipes, thoroughly clean and flux the area, and re-solder. If it's a fitting, tighten it appropriately, being careful not to overtighten.
