How to Replace Grey Polybutylene Pipe with PEX · Step 6 of 9
In this video
The process begins by sliding a copper crimp ring over the end of a red PEX pipe. A brass elbow fitting is then inserted into the end of the pipe. The assembly is positioned within the jaws of the PEX crimp tool. The narrator then exerts considerable effort, using his body weight to squeeze the handles of the tool together, which compresses the copper ring tightly onto the pipe and fitting, creating a secure connection. He expresses surprise at how much force is needed.
Goal: Secure a PEX pipe to a fitting using a copper crimp ring
- Significant physical strength is required to operate the manual PEX crimp tool. Be prepared to apply substantial force.

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.
