How to Replace Grey Polybutylene Pipe with PEX · Step 10 of 10
In this video
The final stage involves finishing the drywall and painting. The drywaller applies joint compound (mud) and tape over the seams of the patches, feathers it out, and sands it smooth. They then apply a texture spray to match the existing wall finish. Once the texture is dry, the patches are primed and painted to blend seamlessly with the surrounding wall color. Finally, all protective coverings are removed and the area is cleaned.
Goal: Restore the walls and ceilings to their original appearance
- Matching existing wall texture can be tricky. It may require specific tools and techniques depending on the original finish (e.g., orange peel, knockdown).

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.
