Place a piece of rubber over the area where the pipe is leaking.
Put the block of wood on top of the piece of rubber.
Open the C-clamp wide enough to surround the pipe, the gasket material, and the block of wood.
Place the stationary part of the opening of the C-clamp against the pipe (opposite the location of the leak) and the screw part of the C-clamp against the block of wood. Tighten the screw clamp until it’s snug.
Using a sleeve clamp
Wrap the damaged section of pipe with the gasket material provided.
Surround the gasket-wrapped pipe with the two semicircular clamps.
Tighten the screws that connect the two halves of the sleeve clamp.
how to permanent Fix a broken pipe
Determine a location for the valve on a water line in or near a heated area.
Shut off the main valve where water comes into your home. Open the lowest fixture in your house to drain any water out.
Use a pipe cutter to remove the desired section of pipe. Rotate the pipe cutter around the pipe, gradually tightening it until it cuts through. Clean any burrs off the end of the cut pipe with steel wool. Place a bucket under the cut area to catch any water remaining in the line.
Cut a new section of copper pipe to the appropriate length. Allow a little extra length for a good fit. Be sure the new pipe is of the same diameter as the existing water line (usually about 1 centimeter).
Use steel wool to clean both the pipe end and inside the stop-and-waste valve.
Spread soldering flux on the outside of both pipes end and inside the copper fitting.
Slide the copper fitting onto the end of the pipe.
Wearing safety goggles, use a propane torch to heat the fitting and the pipe where they connect. For best results, hold the edge of the blue flame right against the pipe.
Push about 5 centimeter of solder into the joint where the copper fitting connects to the pipe. The heat will melt the solder and allow it to seep into the connection. Solder completely around the pipe-valve connection. Practice the soldering technique on scrap pieces of pipe and copper fittings before trying it on the valve.
Use the same soldering techniques to install the new assembly to the water line. Depending on the installation, it may be necessary to use some inexpensive copper fittings to connect new sections of pipe to the existing water line. These copper fittings are widely available in different configurations and diameters
