Using Push-to-Connect (SharkBite) Fittings on Plastic Pipe — Install Transition Fittings

How to Replace a Section of Galvanized Pipe with PEX · Step 4 of 7
In this video
Details the process for using a push-to-connect fitting with plastic tubing, such as PEX or CPVC. For these materials, the white plastic stiffener must be left inside the fitting to provide rigidity to the pipe end, which allows the O-ring to seal correctly. Use a depth gauge tool to mark the proper insertion depth on the plastic pipe. Insert the pipe into the fitting until the mark is flush with the fitting's collar. This ensures a secure and leak-free connection. The fitting can be used to join plastic pipe to copper pipe in the same manner.
Goal: Plumbing Pipes Installation (Standard)
- The plastic stiffener must remain inside the fitting when connecting to PEX or CPVC pipe. Do not remove it.
- Using the depth gauge tool to mark the pipe before insertion is the best way to ensure it's fully seated.

FAQs
How difficult is this project for a DIY beginner, and how long should I expect it to take?
This project is rated for beginners, but it requires careful attention to detail and precision. For replacing a small section, a DIY beginner should realistically budget 2-4 hours, accounting for material gathering, preparation, and thorough leak testing. Factors like pipe accessibility and unexpected issues can extend this timeframe.
What are the most critical safety precautions I need to take when cutting old galvanized pipe and working with water?
Always shut off the main water supply and drain the lines completely before attempting any cuts. Wear appropriate personal protective equipment (PPE), including safety glasses, work gloves, and hearing protection, especially when using a reciprocating saw. Be prepared for residual water and rust flakes to emerge from the old galvanized pipe, and have a bucket and rags ready.
Do I need all the specialized tools listed, or can I use more common alternatives for this PEX replacement?
While specific tools like a PEX pipe cutter and depth gauge are highly recommended for clean, accurate, and reliable PEX connections, some alternatives can be used. A reciprocating saw with a metal-cutting blade is ideal for galvanized pipe, but a pipe cutter can work if space allows. Avoid using a hacksaw for PEX as it can create burrs, hindering a proper seal. Investing in the correct tools minimizes common mistakes.
What are common mistakes DIYers make when connecting PEX to galvanized pipe, and how can I ensure a leak-free joint?
A common mistake is not properly preparing the galvanized pipe end (e.g., failing to clean threads thoroughly, not applying enough pipe dope/Teflon tape) or not fully seating the PEX into push-to-connect fittings. Ensure the existing galvanized pipe end is clean, dry, and free of burrs. For push-to-connect fittings, use a depth gauge to mark the PEX, and push it firmly until it bottoms out inside the fitting, then give it a slight pull to confirm engagement. Test all new connections meticulously before finishing.
