Pipe and Fitting Preparation — Disconnect and Remove Old Valve
Part of project
How to Replace a Two-Handle Shower Faucet · Step 4 of 8
In this video
Before soldering, prepare all components. Cut the copper pipes for the shower riser and tub spout to the necessary lengths using an auto-cut tool or a standard pipe cutter. Use emery cloth to thoroughly clean the outside ends of the copper pipes and the inside of all fittings, including the valve ports and elbows, until they are shiny. This is crucial for a proper solder joint. Next, using pliers and a screwdriver, remove the plastic valve cartridge and the side stops from the brass valve body to protect them from heat damage during soldering.
Goal: Prepare components for soldering
- Failure to remove the valve cartridge before soldering will result in melting the internal components, destroying the valve.

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.
