How to Repipe Your House with PEX

Welcome to this month’s edition of BIG T FIX IT! In this issue, we’ll explore the benefits of using PEX (cross-linked polyethylene) for your plumbing needs and provide a comprehensive step-by-step guide to help you repipe your home efficiently.

Why PEX?

PEX has revolutionized the plumbing industry with its numerous advantages over traditional materials like copper and CPVC. Here’s why it’s the preferred choice for repiping:

Flexibility and Durability

PEX is designed to handle both hot and cold water, making it incredibly versatile. Its flexibility allows for easy installation, reducing the need for multiple fittings and minimizing potential leak points. This makes PEX a durable and reliable option for any plumbing system.

Cost-Effective

When compared to copper and CPVC, PEX is significantly more affordable. Not only are the materials less expensive, but the installation process is quicker, saving you money on labor costs. This cost-effectiveness makes PEX an attractive choice for homeowners looking to upgrade their plumbing without breaking the bank.

Corrosion Resistance

Unlike metal pipes, PEX does not corrode or develop leaks over time. This resistance to corrosion ensures a longer lifespan for your plumbing system, providing a long-lasting solution for your home’s water needs.

Step-by-Step Guide to Repiping with PEX

Repiping your home with PEX can seem daunting, but with careful planning and the right tools, it can be a straightforward process. Follow our step-by-step guide to ensure a smooth installation.

1. Plan and Prepare

Assess Your System: Start by mapping out your existing plumbing system to identify which pipes need replacing. This will help you determine the amount of PEX tubing and other materials required.

Gather Materials: You’ll need PEX tubing, fittings, crimp rings, a crimping tool, and pipe clamps. Make sure to have everything on hand before you begin the project.

2. Shut Off the Water

Turn off your main water supply and drain the pipes by opening all faucets in your home. This will prevent any water from spilling out when you remove the old pipes.

3. Remove Old Pipes

Carefully cut and remove the old pipes. Be mindful of electrical wiring and other potential obstructions to avoid any accidents or damage.

4. Install PEX Tubing

Run PEX Tubing: Install PEX from the main supply to your fixtures. Using manifolds can help efficiently distribute water throughout your home.

Secure Tubing: Use clamps to secure the PEX tubing, preventing movement and reducing noise.

5. Make the Connections

Use PEX fittings and crimp rings to connect the tubing. Ensure each connection is secure by using a crimping tool to avoid any leaks.

6. Test the System

Turn the water supply back on and check for any leaks. Make sure all connections are watertight and functioning properly.

7. Insulate and Finish

Insulate any exposed PEX tubing in areas prone to freezing to prevent damage. Patch up walls and complete any necessary aesthetic work to finish the project.
