When copper pipes are joined with fittings, there is a very small gap between the fitting and the pipe. When the pipe and fitting are heated, and solder is touched to the pipe, the solder melts and is drawn up into the gap through capillary action. Once the gap is filled, and the heat removed, the solder forms a seal and makes a watertight joint.

Caution: Please read our safety information before attempting any testing, maintenance or repairs. Wear eye protection and gloves when soldering and when working with flux. Flux is a toxic substance. Some equipment may rely on a cold water supply. Take appropriate steps to shut down any equipment that may be adversely affected by shutting off the water supply. Such equipment includes, but is not limited to, a boiler or other heating system.

Note: Because you are working with a flame, often in a confined space, be aware of flammable materials near where you are working. In some cases, you may need to set up a non-flammable heat shield between the solder joint and flammable material nearby. Check with your local authority for applicable codes about the work you wish to perform and the necessity of permits before you begin your project.Soldering copper pipes, also called sweating copper, is easy once you get the hang of it. The key is to recognize that you are heating the pipes, not the solder. The heated copper melts the solder. Follow the steps in this guide and you should be able to make watertight joints. It is recommended that you practice a few times on some spare parts until you feel confident

The copper will get shiny as the flux melts. A moment later, the copper will dull as the flux sizzles and begins to smoke. This signals that it's time to apply solder. Now, move the flame away and touch lead-free plumbing solder to the joint. If the joint is horizontal, start at the bottom. Move up the joint, over its top and down the other side - you'll see the solder wick in. For vertical joints, move the solder around the joint, being sure to cover it evenly. After soldering, I like to clean the joint by applying some flux while the copper is still warm, then wiping it thoroughly with a clean rag.
