How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 4 of 7
In this video
Position the new valve assembly inside the wall cavity. Dry-fit the new sections of copper pipe and ProPress fittings to connect the valve to the existing hot, cold, and shower riser pipes. Once you confirm the layout is correct, use a ProPress crimping tool to systematically press each fitting, creating a permanent and watertight connection.
Goal: Plumbing Pipes Installation
- Deburr the ends of the cut copper pipes before pressing to ensure a proper seal and prevent damage to the O-rings inside the fittings.

FAQs
How difficult is it to convert a 3-handle shower faucet to a single-handle, and how much time should I allocate?
This project is rated 'intermediate' due to the need to open walls, modify existing plumbing lines, and ensure proper sealing. You should allocate at least 1-2 full days for the plumbing and wall repair steps, not including time for thinset curing or final trim installation. It's a significant undertaking requiring precision and patience.
Are specialized tools like the oscillating multi-tool with diamond blades truly necessary for this conversion?
Yes, an oscillating multi-tool with diamond blades (e.g., Milwaukee 49-25-2272 or Genesis GAPCS353) is highly recommended. These tools allow for clean, precise cuts through existing tile, grout, or cement board to access the plumbing behind the wall. Using them significantly streamlines the process, reduces damage to surrounding areas, and is often more efficient than traditional methods.
What are the most critical safety precautions to take when opening walls and modifying plumbing lines?
Always shut off the main water supply to your home before starting any plumbing work and verify with a faucet. Wear appropriate personal protective equipment (PPE), including safety glasses, work gloves, and a dust mask, especially when cutting walls or pipes. Before cutting into walls, use a stud finder and be mindful of potential electrical lines or hidden pipes.
What are the most common pitfalls during this conversion, especially regarding leaks, and how can I avoid them?
The most common mistake is improper pipe connections (soldering, PEX crimping), leading to leaks. Ensure all connections are clean, dry, and properly sealed before testing the system under pressure. Another pitfall is inadequate support for the new valve body; secure it firmly to framing using mounting brackets to prevent future movement and leaks. Always perform a thorough leak test before closing up the wall.
