How to Replace a Two-Handle Shower Faucet · Step 5 of 8
In this video
Place the new shower valve into its mounting bracket and secure it. Connect new PEX or copper pipes to the hot, cold, and shower riser ports on the valve. Use appropriate press fittings and a press tool to create secure, watertight connections on all pipes. Ensure the shower riser pipe is properly positioned and secured.
Goal: Install and connect the new shower valve
- Make sure to connect the hot and cold water lines to the correct ports on the valve, which are typically marked 'H' and 'C'.

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.
