Create Wall Access — Access the Valve Body
Part of project
How to Replace a Two-Handle Shower Faucet · Step 3 of 8
In this video
To begin the project, access the plumbing behind the shower. Use a level to draw straight, level lines on the drywall to mark out an access panel. Then, use an oscillating multi-tool to carefully cut along the marked lines. Once all sides are cut, remove the section of drywall to expose the wall cavity containing the shower valve and pipes.
Goal: Access in-wall plumbing
- Cut the drywall panel cleanly so it can be easily patched or reinstalled later.
- Wear safety glasses and a dust mask when cutting drywall.

FAQs
Is this project truly 'intermediate,' and what specific skills do I need to successfully replace my two-handle shower faucet?
Yes, this project is rated intermediate primarily because it involves soldering copper pipes, which requires practice and a steady hand. You'll also need basic carpentry skills for opening and repairing the access hole, and a good understanding of how to properly shut off and drain your home's water supply. If you're new to soldering, practice on scrap copper pipe first to gain confidence before working on the live plumbing.
What are the most critical safety precautions I should take when working with a propane torch and soldering pipes inside a wall?
Always ensure proper ventilation to dissipate fumes, and keep a fire extinguisher or bucket of water nearby in case of accidental ignition. Clear the work area of all flammable materials like insulation, wood studs, and plastics before beginning to solder. Wear appropriate safety glasses and heat-resistant gloves, and never point the torch flame at anything other than the pipe connection you are working on.
How can I prevent leaks after installing the new valve, and what should I do if I discover one during the initial test?
To prevent leaks, ensure all pipe ends and fittings are clean, properly fluxed, and heated evenly for the solder to flow completely around each joint. After soldering, perform a thorough leak test by slowly turning the water back on and checking every new connection with a dry paper towel for at least 15-30 minutes. If you find a leak, turn off the water immediately, drain the line, and re-solder the faulty joint after inspecting it for imperfections.
Do I really need specific tools like a propane torch and plumbing solder, or are there alternative connection methods for a DIYer?
This project, as detailed, requires soldering for a professional and durable connection, which necessitates a propane torch, lead-free solder wire, and flux paste. While alternatives like push-to-connect (e.g., SharkBite) or press-fit fittings exist and don't require a torch, they often cost more per fitting and require different specialized tools. Soldering is a reliable and common method for copper plumbing, offering a secure, long-lasting seal.
