Preparation and Access — Disconnect and Remove Old Valve
Part of project
How to Replace a Two-Handle Shower Faucet · Step 4 of 8
In this video
Begin by assessing the work area. The old valve has been removed, leaving an access hole in the tile wall with the hot and cold copper pipes exposed. Stuff rags into the wall cavity below the pipes to catch any debris and prevent tools or parts from falling down the wall. Ensure the main water to the house is shut off and the lines are drained. Remove any temporary caps, such as the SharkBite caps shown, from the ends of the pipes.
Goal: Prepare the work area and access the pipes
- Using rags to block the wall cavity is a simple trick that can save you a lot of trouble if you drop a small part.
- Double-check that the water is off by opening a nearby faucet before starting any cutting or disassembly.

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.
