Ratchet-Style Cutters for Larger Diameters
For those larger PEX pipes or when dealing with plumbing systems that require bigger diameters, a ratchet-style cutter is your best friend. It provides the leverage and precision needed for those heftier jobs.
Step-by-Step Guide to Cutting PEX Pipe
Alright, now that you’ve got your tools ready, let’s get down to the nitty-gritty of cutting that PEX tubing.
Marking the Desired Length
- Lay out your PEX tubing on a flat surface.
- Using a measuring tape, determine the length you need.
- Mark the spot with a non-permanent marker. This ensures you get the exact length required for your plumbing project.
Ensuring a Straight Cut
- Hold the PEX tubing firmly with one hand.
- With your chosen cutting tool, position the blade at the marked spot.
- Apply steady pressure and make a straight cut. Remember, a straight cut is crucial for preventing leaking pipes and ensuring a snug fit with your fittings.
Tips to Avoid Burrs or Ragged Edges
- Always use sharp cutting tools. Dull tools can lead to ragged edges.
- After cutting, inspect the end of the PEX tubing. If you notice any burrs, use a deburring tool or fine-grit sandpaper to smooth them out.
- Avoid using a utility knife or scissors for precise cuts. As mentioned earlier, they can lead to less-than-perfect results.
Safety Precautions
Safety first! Before you even think about making that first cut, let’s ensure you’re taking the necessary precautions.
Wearing Gloves to Prevent Cuts
PEX tubing might seem soft, but a slip of the hand can lead to nasty cuts. Always wear gloves, preferably made of a durable material, to protect your hands. Not only will they shield you from potential injuries, but they’ll also give you a better grip on your plumbing tools and materials.
Keeping the Cutting Tools Sharp for Clean Cuts
A dull pipe cutter or utility knife can lead to jagged edges, which can cause leaking pipes down the line. Regularly sharpen your tools or invest in high-quality cutting tools that retain their edge. Remember, in the world of plumbing, precision is key.
Connecting PEX to Other Materials
PEX is versatile, but chances are, you’ll need to connect it to other types of pipes in your plumbing system. Here’s how:
Joining PEX to Copper Using Male Sweat Adapters
Copper pipes have been a staple in plumbing for years. To connect PEX tubing to copper:
- Slide a copper crimp ring onto the PEX tubing.
- Push the tubing onto the copper pipe until it touches the shoulder of the fitting.
- Use a crimping tool to secure the connection. Ensure you’re following plumbing codes and standards for a secure fit.
Connecting PEX to CPVC with Cinch Clamps
CPVC pipes are commonly used in home plumbing systems. To connect PEX to CPVC:
