Install and Plumb New Valve — Demolish Old Valve
Part of project
How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 4 of 9
In this video
With the old valve removed, position the new pressure-balance valve in the opening. Dry-fit new sections of copper pipe and fittings to connect the new valve to the existing hot supply, cold supply, shower head pipe, and the tub spout pipe. Ensure all pipes are cut to the correct length and the valve body is centered in the wall opening. Clean all copper pipe ends and fittings and apply flux in preparation for soldering.

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.
