Connect PEX to Copper Pipe with Push Fitting — Mark Depth and Install Fittings
Part of project
How to Make a Quick Pipe Repair with Push-to-Connect Fittings · Step 5 of 6
In this video
Prepare the existing copper pipe by thoroughly cleaning the end with the copper cleaning brush to remove any burrs or oxidation. Measure and cut the PEX tubing to the appropriate length to connect to the copper pipe. Use a marker to indicate the proper insertion depth on both the copper pipe and the PEX tubing, based on the requirements of the push-to-connect fitting. Firmly push the coupling onto the copper pipe up to the mark, then insert the PEX tubing into the other side of the fitting, also pushing it firmly until it reaches its mark.
Goal: Join new and existing plumbing
- Failure to push the pipes fully into the fitting is a common cause of leaks. The depth mark is a critical guide to ensure a proper connection.

FAQs
What are the most crucial safety precautions I need to take before starting this pipe repair?
Always shut off the main water supply to your home completely before beginning any plumbing work to prevent flooding. Wear safety glasses, such as the HDX Indoor Safety Glasses, to protect your eyes from debris or splashing water during cutting and draining. Having an emergency shut-off valve like the Rheem Preferred Series Remote Water Shut-Off Valve can make this step quicker.
Why is deburring the pipe ends so important after cutting, and what tool should I use?
Deburring creates a smooth edge on the cut pipe, which is crucial for a watertight seal with push-to-connect fittings and prevents damage to the internal O-rings. Use a dedicated tool like the Husky 1-5/8 in. Inner/Outer Reamer and Deburring Tool to quickly and effectively prepare your pipe ends after cutting with a RIDGID tubing cutter.
How can I ensure the push-to-connect fitting is properly installed to avoid future leaks?
First, use a permanent marker, like a Sharpie, to clearly mark the insertion depth on your pipe according to the fitting's specifications. Then, push the fitting firmly onto the pipe until it reaches your mark, ensuring a secure and leak-free connection. Give the fitting a slight tug to confirm it's seated properly and won't pull off.
The project estimates 3 hours; is this realistic for a beginner, and what might make it take longer?
Three hours is a reasonable estimate for someone new to plumbing, assuming you have all tools ready and the leak is easily accessible. Factors like difficulty locating the main shut-off, unexpected pipe damage, or working in tight, cramped spaces can extend the project time significantly. It's always best to budget extra time.
