Cutting the Pex Pipe
Cutting the PEX pipe is a straightforward process that requires a few simple tools. Here’s a step-by-step guide to ensure a clean and precise cut.
1. Measure and Mark the Cutting Point
Determine the desired length of the new PEX hose bib and mark the cutting point on the existing pipe using a permanent marker or a utility knife. Ensure the measurement is accurate to avoid cutting the pipe too short or long.
2. Secure the Pipe
Clamp the PEX pipe firmly using a pair of slip-joint pliers or a small pipe wrench. This will prevent the pipe from moving or vibrating during cutting.
3. Score the Pipe
Using a sharp utility knife or a specialized PEX cutter, lightly score around the pipe at the marked cutting point. Rotate the pipe slightly while scoring to create a uniform cut.
4. Snap the Pipe
Once the pipe has been scored, grip it firmly on both sides of the cut and apply force to snap it apart. Ensure that the cut is perpendicular to the pipe’s axis to prevent leaks or damage.
5. Deburr the Pipe Ends
Using a sharp knife or a deburring tool, carefully remove any burrs or sharp edges from the cut ends of the pipe. This step is crucial to ensure a smooth connection and prevent leaks. To effectively deburr the pipe:
Sealing the Joints
To ensure a watertight seal, it’s crucial to apply thread sealant to all threaded connections. Here’s a step-by-step guide:
-
Wrap the Threads
Apply a generous amount of thread sealant to the male threads of the compression fitting or hose bib. Ensure that you cover the entire length of the threads, avoiding getting sealant inside the fitting or onto the hose threads.
-
Screw the Parts Together
Hand-tighten the compression fitting or hose bib onto the supply line. Avoid overtightening, as this can damage the threads or seal.
-
Tighten the Connection
Using a wrench or pliers, tighten the connection further. For compression fittings, turn clockwise until you feel resistance, being careful not to overtighten. For hose bibs with set screws, tighten the screws until snug, ensuring the bib is securely fixed to the wall or siding.
-
Test the Connection
Turn on the water supply and check for any leaks around the joints. If you notice any dripping or seepage, tighten the connection further until the leak stops.
