Solder Assembly in Place — Preparation and Safety
Part of project
How to Solder Copper Pipes for a Permanent, Watertight Joint · Step 1 of 9
In this video
With the new fittings prepared, solder the assembly in place. Slide the prepared elbow onto the existing copper pipe coming from the shutoff valve. Protect the wall and any nearby flammable materials with a wet rag or heat shield. Heat the joint with the torch until it's hot enough to melt the solder. Apply the solder to the joint, allowing it to wick all the way around and create a complete seal. Be careful not to set the wall on fire.
Goal: Plumbing Pipes Repair (Leaking)
- The video shows the wall getting scorched. Always use proper heat shielding to prevent fire.
- Heat the brass valve body more than the copper pipe, as brass takes longer to heat up.
Used in this video
- Propane Torch (brand: Bernzomatic) — Heating the copper pipe and brass valve for soldering.
- Wet Rag — Protecting surrounding surfaces from the torch flame and cooling the joint.

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.
