Preparation and Access — 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
Begin by assessing the work area. The old valve has been removed, leaving an access hole in the tile wall with the hot and cold copper pipes exposed. Stuff rags into the wall cavity below the pipes to catch any debris and prevent tools or parts from falling down the wall. Ensure the main water to the house is shut off and the lines are drained. Remove any temporary caps, such as the SharkBite caps shown, from the ends of the pipes.
Goal: Prepare the work area and access the pipes
- Using rags to block the wall cavity is a simple trick that can save you a lot of trouble if you drop a small part.
- Double-check that the water is off by opening a nearby faucet before starting any cutting or disassembly.

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.
