Leakage of the copper fittings is a dangerous problem to the pipes. Leaking copper fittings are usually caused by a poorly soldered joint or a worn-out joint that is no longer watertight. Once this happens, the joint must be opened again and resoldered to be sure the repair is watertight when completed. This article will show methods and procedures of repairing copper fittings in a water line.
1. Turn off the water valve supplying the leaking joint. This could be a small shut-off valve near the leaking joint.
2. Light a torch with a striker, a match or a lighter, and begin heating the joint. When the joint is sufficiently hot, pull the water lines away from the leaky copper fitting. Nest process is to immediately wipe the excess solder away from the ends of the pipes that the fitting were connected to while they are still hot and discard the old copper fitting.
3. When the ends of the water lines have cooled, rub the ends with a piece of cloth. This will clean them and help the pipes accept soldering more readily. Brush a layer of flux onto the ends of the pipes, and place a new copper fitting over them. When the copper fitting is sufficiently hot, the solder will immediately melt upon contact. Touch the solder to the edge of the fitting, and run the solder around the whole copper fitting. Repeat for the other pipes attached to the fitting.
4. Allow the repaired fitting to cool and then turn the water supply to the copper fitting back on to test for further leaking. The water will also finish cooling the copper fitting from inside the pipe so it will be safe to touch.
