DIFFICULTY RATING: (3 out of 5 - Moderate)

A corroded shutoff valve can start to leak. Consider replacing the valve to save water and prevent water damage.
Step 10: Assemble and solder the remaining connections.
Fit the soldered valve and pipe assembly into place, twisting and pushing until it is tightly in place. Turn the valve to the open position and make sure the handle is temporarily removed. Follow the direction in Step #7 to heat the coupling until the flux melts. Rub the solder to the heated joint until it melts and flows freely, and remove the solder and heat. Repeat this process for the valve end of the assembly. Be sure to avoid exposing the valve mechanism to direct heat. Once both ends are soldered and cool, you can use a wet rag to smooth the joint and remove excess solder.
Rub the solder to the joint at the heated gate valve end.
