Copper is a durable, clean material for plumbing that can be joined using solder for a leak-free connection
Copper pipe has been used for plumbing for a long time because of its many great qualities, including durability, flexibility, resistance to bacteria and ease of installation. Copper pipe is also environmentally friendly since it can be recycled.
This guide will show you how to use solder to connect copper pipes to ensure no leaks.
WHAT YOU NEED FOR THIS PROJECT
Ream the inside of each fitting with a wire brush.
• Use emery cloth or steel wool to clean the outside of the pipe.
• Use a deburring tool or the handle of a pair of pliers to deburr the inside of the pipe.
• Apply a thin layer of lead-free soldering paste (flux) to the end of the pipe using a flux brush. The paste should cover about 1 inch of pipe.
• Insert the pipe into the fitting, making sure it is tight against the bottom of the fitting.
• Twist the fitting slightly to spread the flux.
You will need 8 to 10 inches of the wire extended from the spool. Bend the first 2 inches to a 90-degree angle.
• Light the propane torch.
• Hold the tip of the flame against the middle of the fitting for 4 to 5 seconds or until the soldering paste begins to sizzle.
• Heat the opposite side of the fitting to ensure the heat is evenly distributed.
If the solder melts, the pipe is ready to solder.
Quickly insert ½ to ¾ inches of solder into the joint.
• Wipe away the excess solder with a rag.
• After the pipe and fitting have cooled, install the pipe, turn on the water and check for leaks.
• If the joint leaks, take it apart and resolder it.
