How to Replace Grey Polybutylene Pipe with PEX · Step 10 of 10
In this video
To repair the wall, first install pieces of wood (like 1x2s or 2x4s) inside the opening to act as backing for the drywall patch. Re-insert the piece of drywall you cut out earlier and secure it to the wood backing with drywall screws. Apply self-adhesive mesh tape over all the seams. Then, use a putty knife to apply a thin layer of joint compound over the tape and screw heads. Once dry, apply additional coats as needed, sand smooth, and then apply texture and paint to match the rest of the wall.
Goal: Repair the access hole in the wall for a finished look.
- An alternative to patching is to install a plastic plumbing access panel, which simplifies future repairs.

FAQs
Given the 40-hour estimate, is a whole-house PEX repipe truly an 'intermediate' DIY project, or should I hire a professional?
While labeled intermediate, this project demands significant time, precision, and adherence to plumbing codes. It's suitable for experienced DIYers comfortable with tools and problem-solving, but if you're unsure about the complexity or time commitment, consulting a licensed plumber is advisable, especially for main supply connections and final inspections.
What are the most crucial safety precautions I must take when replacing polybutylene pipes with PEX?
Always shut off and thoroughly drain the main water supply before starting. Wear appropriate PPE, including eye protection, and ensure good ventilation if soldering is required for main tie-ins. Be cautious when cutting into existing lines to prevent accidental damage or uncontrolled water release, and always have a plan for containing potential leaks.
The project lists specific PEX tools like crimp tools and cutters. Are these absolutely essential, or are there budget-friendly alternatives?
Yes, specialized PEX tools such as a PEX pipe cutter and a crimp/clamp tool are essential for making reliable, leak-free connections. While there are different brands and price points, investing in quality PEX-specific tools is crucial for successful installation. Avoid using standard tools for PEX connections, as they can lead to costly leaks and system failures.
What are common mistakes DIYers make during PEX installation, particularly with crimp connections, and how can they be avoided?
Common mistakes include improper crimp ring placement, not fully deburring cut pipes, and over-tightening manifold connections. Always ensure the crimp ring is correctly positioned over the fitting's barb, deburr all pipe ends to prevent leaks, and follow manufacturer guidelines for manifold valve torque. Testing sections of the system as you go can help catch issues early.
