Disconnect Water Supply and Fixtures — Remove Old Valve Body

How to Convert a 3-Handle Shower Faucet to a Single-Handle Valve · Step 4 of 9
In this video
Before starting, ensure the main water supply to the area is completely shut off. Using a reciprocating saw with a metal-cutting blade, carefully cut through the stems of the hot and cold faucet handles and the tub spout to remove them. Then, from the front or through an access panel behind the wall, cut the copper pipes supplying the valve body. This includes the hot water line, the cold water line, and the shower riser pipe. A longer reciprocating saw blade may be necessary to reach all pipes effectively.
Goal: Cut and remove faucets and water supply lines
- Triple-check that the water is off before making any cuts.
- A longer reciprocating saw blade can help reach pipes tucked deep inside the wall cavity.

FAQs
Given the 'intermediate' difficulty, what's the most challenging part of this conversion, and can I realistically finish it in 12 hours?
The most challenging aspects are accurately cutting and soldering copper pipes for the new valve, and then skillfully repairing the wall to a professional finish. While 12 hours is an estimate for experienced DIYers, expect it to take longer if you're new to soldering or drywall work, especially accounting for drying times for joint compound.
What are the essential safety precautions I must take when cutting and soldering plumbing, and opening up a wall?
Always shut off your home's main water supply completely before starting any plumbing work. When soldering, ensure good ventilation, wear eye protection, and keep a fire extinguisher nearby. Be extremely careful when cutting into the wall to avoid hidden electrical wires, gas lines, or other pipes.
The required tools list includes items like an awning and weatherstripping. Are these really necessary for this specific plumbing project?
Some items in the provided list, such as the awning, weatherstripping, and wall switch, appear to be irrelevant for converting a shower faucet. Focus on essential plumbing tools like a pipe cutter, reamer, soldering torch, copper fittings, flux, and solder, alongside basic carpentry tools for wall repair, and a drill/driver for mounting.
What's the most common mistake DIYers make when soldering copper pipes, and how can I avoid leaks?
A frequent mistake is not properly cleaning and fluxing the pipe ends and fittings before heating, which prevents a strong capillary bond. Ensure surfaces are shiny clean, apply flux evenly, heat the fitting (not the solder) until the solder flows into the joint, and avoid moving the joint until it cools to prevent pinhole leaks.
