Dry Fitting the Valve and Pipes — 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
With the valve body, first attach the black plaster ground using the two escutcheon screws. This piece helps position the valve correctly within the wall. Determine if you have a thick or thin wall, as this affects valve placement. The center of the valve should be 32 inches from the floor of the tub. Begin by connecting the valve to the tub drop outlet pipe. Measure the distance, cut a piece of 1/2' copper tubing to length, and dry fit it using a copper coupling. Repeat this process for the hot water inlet, cold water inlet, and the shower riser outlet, using slip couplings for easier alignment. This dry-fitting stage ensures all pipes are the correct length and angle before soldering.
Goal: Position and connect the new valve
- The tub drop outlet must be 1/2' copper pipe for the valve to function properly.
- The center of the valve should be positioned 32 inches from the tub floor.
- Use half-inch copper slip couplings for the hot, cold, and shower riser connections to provide more flexibility during installation.

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.
