How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 8 of 9

Once all parts are cleaned, apply a thin layer of flux to all pipe ends and the inside of the fittings. Assemble the new valve in a vise. Use a propane torch to heat each joint, focusing the heat on the heavier valve body. When the copper is hot enough, touch the solder to the joint, allowing it to be drawn in and create a seal. Wipe away any excess with a damp cloth while the solder is still molten.

FAQs
What type of torch is best for soldering copper pipes, and how do I know I'm applying enough heat?
The K Tool International Self Igniting Propane Torch Head is sufficient for most residential copper pipe soldering. You'll know you're applying enough heat when the pipe and fitting are hot enough to melt the Oatey Safe Flo Lead-Free Solder *by touching the pipe*, not the flame. The solder should then be drawn into the joint by capillary action.
What are the critical safety precautions I must take when soldering pipes indoors?
Always have a fire extinguisher nearby and remove any flammable materials from the work area, especially when using a torch. Ensure good ventilation to disperse solder fumes, and wear safety glasses to protect your eyes from splashes or heat. It's also crucial to turn off the main water supply before starting to avoid accidents and ensure pipes are dry.
Is it really necessary to deburr, ream, and thoroughly clean the pipes before soldering?
Absolutely. Deburring and reaming with a tool like the Husky 1-5/8 in. Inner/Outer Reamer ensures a smooth pipe interior for optimal water flow and prevents solder from being blocked. Thorough cleaning with sandpaper and applying Oatey H-20 Flux are critical to remove oxidation, allowing the solder to properly bond and create a strong, watertight seal.
What are the most common reasons a soldered joint might leak, and how can I avoid them?
Leaks often occur due to insufficient cleaning, inadequate heat application, or not using enough solder. Ensure pipes are shiny clean before applying Oatey H-20 Flux, heat the joint evenly until it can melt the solder, and feed enough solder to completely fill the joint. If a joint leaks, it must be desoldered, thoroughly cleaned, and resoldered.
