Soldering Copper Plumbing

Much of the plumbing in the modern home consist of copper pipes. Copper is durable, easy to work with and doesn't rust like iron or steel. Lengths of copper plumbing are connected together via couplings, Ts and elbows. The connection is sealed using solder and a propane torch. Shutoff valves can also be soldered, although in many modern applications a compression fitting is used. No matter what the copper plumbing task, you can achieve professional results by following a straightforward procedure.


Tools Of The Trade
Emery paper
Propane torch
Silver solder
Bucket of cool water
Rag

Step 1:
Clean the ends of the copper pipe being soldered as well as the insides of the coupling, T or elbow being used. Use emery paper to rub off any oils or dirt on the copper, which can prevent you from achieving a solid solder joint. Place a bucket of cool water in the work area in case flammable material around the pipe becomes ignited.

Step 2:
Fit the copper pipes into the coupling, T or elbow and ensure they are completely and evenly inserted.

Step 3:
Light the propane torch and adjust the flame so that the tip of it is blue.

Step 4:
Hold the tip of the flame on the joint you are soldering for about 30 seconds to heat the metal thoroughly.

Step 5:
Touch the tip of the silver solder to the joint while continuing to hold the torch's flame on the joint but not directly on the solder. The solder will melt when touched to the heated copper and roll around the joint. Move the tip of the solder around the entire circumference of the joint to esnure it has a bead of solder on it. Place a cool damp rag on the joint to cool the solder quickly.
