Install New Single-Handle Valve — Install and Plumb New Valve
Part of project
How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 4 of 7
In this video
Once the old valve is removed, the new single-handle shower valve must be installed. This involves connecting the new valve body to the existing hot and cold water supply lines and the shower riser pipe. The valve must be securely mounted to a wooden support (stud or cross-brace) inside the wall at the correct depth to align with the finished wall surface.
Goal: Install New Valve Body
- Carefully follow the manufacturer's instructions to ensure the valve is set at the proper depth. If it's too deep or too shallow, the trim will not fit correctly.
Used in this video
- Pipe Cutter — Cutting the copper or PEX pipes to fit the new valve.
- Soldering Torch — Soldering copper pipes to the new valve body. Alternatively, push-to-connect fittings can be used.
- Screwdriver — Securing the valve body to the wood support inside the wall.

FAQs
How challenging is this conversion for an intermediate DIYer, and what's a realistic time frame?
This project is rated intermediate due to the necessary plumbing and wall repair. While feasible for a dedicated DIYer, expect it to take a full weekend or several evenings, especially if you encounter unexpected plumbing configurations or need to learn new techniques. Adequate planning and preparation can significantly reduce the overall time.
What critical safety precautions should I take when working on this plumbing project?
Always shut off the main water supply to your house before starting any work to prevent flooding. Wear eye protection when cutting pipes or using power tools. Before cutting into walls, use a stud finder and potentially a non-contact voltage tester to avoid electrical wires or hidden pipes, which could cause injury or damage.
What are common pitfalls or mistakes DIYers make, and how can I avoid them during this valve conversion?
A common mistake is not fully draining the lines after shutting off water, leading to unexpected drips. Another is failing to adequately test for leaks before repairing the wall, which can cause significant damage later. Ensure all new connections are tight, test the system thoroughly for at least an hour before closing up the wall, and double-check pipe routing for any potential strain.
The project mentions specific tools and materials like push-to-connect fittings. Are these highly recommended, and what are their benefits?
Yes, specific tools like the GEARWRENCH Mini Tubing Cutter and Husky Reamer are crucial for clean copper pipe work. Push-to-connect fittings (e.g., QUICKFITTING) are highly recommended as they significantly simplify plumbing connections, eliminating the need for soldering tools and skills. This makes the project much more accessible and faster for DIYers while providing reliable seals.
