How to Make a Quick Pipe Repair with Push-to-Connect Fittings · Step 4 of 7
In this video
For each pipe, use a tape measure to determine the distance between the two marks you made. Add 1/8th of an inch to this measurement. This final calculated length is the amount that needs to be cut off the end of the pipe. Mark this cut line clearly around the circumference of the pipe. Using a reciprocating saw for the smaller pipe and an angle grinder for the larger one, carefully cut each pipe at the marked line. Repeat the entire process for the second pipe.
Goal: Cut pipes to correct length
- Ensure the cut is as straight and square as possible for a proper fit.
- Wear safety glasses during all cutting operations.

FAQs
Do I need special tools like a tubing cutter and reamer, or can I use basic tools I already own for this repair?
Yes, a dedicated tubing cutter and a deburring tool are highly recommended for this project. They ensure clean, straight cuts and smooth pipe ends, which are crucial for a leak-proof seal with push-to-connect fittings. Using incorrect tools can damage the pipe or compromise the fitting's integrity.
What's the most critical safety step I need to take before starting any plumbing repair, especially this one?
The absolute most critical step is to completely shut off the main water supply to your home or the affected area and drain the pipes thoroughly. This prevents accidental flooding and ensures you can work safely without water pressure. Always double-check by opening a nearby faucet to confirm no water is flowing.
Is the 2-hour estimated time realistic for a beginner, and what might make the project take longer?
For a beginner, 2 hours is a realistic estimate if you have all your tools and materials ready and the damaged section is easily accessible. The project might take longer if you encounter unexpected pipe types, struggle to make straight cuts, or need extra time to locate and operate your home's main water shut-off valve.
What are the most common mistakes beginners make when installing push-to-connect fittings, and how can I avoid leaks?
Common mistakes include not properly deburring pipe ends, failing to mark the correct insertion depth, and not pushing the pipe fully into the fitting. To avoid leaks, ensure all pipe ends are smooth, mark the recommended insertion depth from the fitting's instructions, and apply firm, even pressure until the pipe is fully seated.
