The user installs the remaining fixtures. He applies Teflon tape and pipe dope to the shower arm threads and screws it into the drop ear in the wall, tightening it with channel-lock pliers. He then screws on the shower head. For the tub spout, he applies sealant to a brass nipple and installs it, then caulks around the hole before sliding the tub spout on and tightening its set screw.
Goal: Plumbing Fixture Installation
- The new, square shower head leaked and had to be replaced with the old one, indicating a potential defect in the new fixture.
- Caulk the opening around the tub spout pipe before installing the spout to prevent water from getting behind the wall.

FAQs
How difficult is it to convert a 3-handle shower to a single-handle, and what kind of time and cost commitment should I expect?
This is an intermediate-level plumbing project that requires opening the wall, re-plumbing, and soldering, making it more involved than simple fixture replacement. Expect it to take a dedicated DIYer 1-2 full days, allowing for unforeseen issues, drying times for wall materials, and thorough testing. Costs can vary significantly based on the new single-handle valve kit's brand and features, plus materials for wall repair.
What specialized tools or skills are absolutely essential for this conversion beyond basic hand tools?
You will need plumbing skills like soldering copper pipes, which requires a propane torch, solder, and flux, along with a tube cleaning brush. An oscillating multi-tool is invaluable for cleanly cutting out the old valve and opening the wall. For wall repair, especially if tiled, a diamond saw blade for cutting cement backer board is necessary, along with general tools for finish work.
What are the most important safety precautions to take when undertaking this plumbing and wall modification project?
Always shut off the main water supply to your home before starting any plumbing work to prevent flooding. When soldering, ensure proper ventilation, have a fire extinguisher nearby, and use heat shields to protect surrounding studs and wiring from the torch flame. Wear appropriate personal protective equipment, including safety glasses and gloves, especially when cutting walls or handling pipes.
What are common mistakes DIYers make during the re-plumbing and soldering phase, and how can they be avoided?
A common mistake is inadequate pipe preparation before soldering, which can lead to leaks; ensure all pipe ends are thoroughly cleaned with a tube cleaning brush and sandpaper, then apply flux evenly. Another error is applying too little or too much heat during soldering, so practice on scrap pieces to achieve strong, leak-free joints. Double-check all connections before turning the water back on.
