This Old House plumbing and heating expert Richard Trethewey shares tips on soldering pipe. (See below for shopping list, tools, and steps.) SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Shopping List for How to Solder a Pipe: - Lead-free solder - Flux and acid brush to ensure solder bonds to copper pipe and fittings - Propane cylinder - Dry cloth Tools List for How to Solder a Pipe: - Safety glasses - Propane torch with striker to melt solder - Tubing cutter to cut copper pipe - Emery cloth or Cleaning brush to clean copper pipe and fittings - Screw-on torch tip to attach to the propane cylinder - Heat shield to prevent torch flame from burning combustible surfaces Steps for How to Solder a Pipe: 1. Use a cleaning strip or an emery cloth to clean the outside of the copper pipe and the inside of the copper fitting. 2. Use an acid brush to apply flux onto the pipe end and inside the fitting. 3. Push the fitting onto the pipe until they fit tightly together. 4. Thread the torch tip onto the propane cylinder, then open the valve and ignite the propane with a striker or a built-in igniter. 5. Adjust the valve to create a sharp, well-defined pencil-tip flame. 6. Use the torch to apply heat to one side of the copper fitting. 7. Once the flux starts to bubble, press the solder against the opposite side of the fitting. 8. Wait for the heat to melt the solder, then and draw the solder into the joint. 9. Remove the flame and gently wipe away any excess solder with a dry cloth. 10. When soldering existing pipes, be sure to drain all water out of the pipes first. 11. Use a fireproof heat shield to protect wood framing, insulation and other combustibles from the torch flame.

Our final episodes of Anatomy & Physiology explore the way your body keeps all that complex, intricate stuff alive and healthy -- your immune system. The immune system’s responses begin with physical barriers like skin and mucous membranes, and when they’re not enough, there are phagocytes -- the neutrophils and macrophages. It also features the awesomely named natural killer cells and the inflammatory response, and we ll explain how all of these elements work together to save the day if you happen to slip on a banana peel.
