How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 6 of 9
In this video
Take the old valve assembly to a workbench to use as a template. Measure and cut new half-inch copper pipes to duplicate the original configuration. Before soldering, thoroughly clean the outside of all pipe ends and the inside of all fittings using sandpaper and a pipe cleaning brush. It is critical to also remove the plastic cartridge and rubber stoppers from the new valve body to prevent them from being damaged by the heat of the torch.
Goal: Fabricate and prepare the new valve for soldering
- Removing the internal plastic and rubber parts of the valve before soldering is essential to avoid melting and ruining them.

FAQs
This project is rated 'intermediate.' What specific skills or prior experience are essential for successfully converting a three-handle shower faucet?
An intermediate rating means you should be comfortable with basic plumbing tasks, including cutting pipes and making secure connections. Experience with soldering copper pipes is crucial, as the new valve typically requires soldered connections. You'll also need basic carpentry skills for opening and repairing the access wall.
The estimated time is 16 hours. What aspects of this conversion project take the most time, and can it be completed in a single weekend?
The 16-hour estimate accounts for significant stages like creating wall access, carefully removing the old valve, precisely soldering the new one, and thorough leak testing. Repairing and finishing the access wall also adds considerable time. While possible to do in a weekend, spreading it over a few days allows for drying times and meticulous work, especially for leak checks.
What are the critical safety considerations, especially regarding soldering and working with plumbing behind the wall?
Always turn off the main water supply before starting. When soldering, ensure excellent ventilation to disperse fumes and have a fire extinguisher nearby; protect surrounding studs with a heat shield. Wear appropriate PPE, including safety glasses and gloves. Thoroughly drain pipes to avoid steam buildup during soldering.
What are the most common mistakes DIYers make during this type of shower valve conversion, and how can they be avoided?
A common mistake is improper soldering, leading to leaks. Ensure pipes are clean, flux is applied correctly, and joints are heated evenly. Another error is not thoroughly leak testing before closing the wall; pressurized water should run for several hours. Also, double-check the new valve's orientation and depth before securing it.
