In this video
After the plumbing repair is complete and tested, clean up any debris from inside the wall. Cut a new piece of drywall to fit the opening precisely. If necessary, add wood backing or 'cleats' inside the wall cavity, attached to the existing studs, to provide a surface for the edges of the patch to screw into. Secure the drywall patch to the studs and backing using drywall screws with a drill.
Goal: Repair Drywall Holes
- Slightly countersink the drywall screws just below the surface of the paper without tearing it. This allows for a smooth finish when applying mud.

FAQs
Is replacing polybutylene with PEX a suitable DIY project for someone with limited plumbing experience?
This project is rated 'intermediate' and is quite involved, requiring significant time (40 hours) and attention to detail. While achievable for a determined DIYer, it demands careful planning, systematic execution, and a willingness to learn new skills like PEX connection. If you're unsure about tackling major plumbing, consider hiring a licensed plumber for the main connections or at least consulting one for advice.
What are the most important safety precautions to take when undertaking this major plumbing replacement?
Always ensure the main water supply to your home is completely shut off and lines are drained before starting any work. Exercise extreme caution when cutting into walls to avoid electrical wires, gas lines, or other hidden utilities. Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, throughout the project, especially when using power tools or handling sharp objects.
Do I need specialized tools to make secure PEX connections, or can I use basic plumbing tools?
Yes, specialized tools are essential for secure PEX connections. You will need a PEX cinch tool (or crimp tool) to properly fasten the cinch rings onto the fittings, ensuring a leak-proof seal. While not listed, a dedicated PEX pipe cutter is also highly recommended for making clean, straight cuts that are vital for good connections. Do not attempt to use generic pliers or cutters, as this will compromise the connection integrity.
What are the most common mistakes DIYers make when installing PEX, and how can I avoid leaks?
The most common mistakes are improper seating of the PEX pipe onto the fitting, and incorrect crimping or cinching of the ring. To avoid leaks, ensure the PEX pipe is fully pushed onto the fitting's barb and that your cinch tool is properly calibrated. After crimping, visually inspect each connection and give it a firm tug to confirm it is secure before moving on.
