Soldering a drain pipe, typically made of copper, involves heating the fitting, applying flux, and then melting solder into the joint to create a waterproof seal. Here's a breakdown of the process based on the reference:
-
Apply Flux: After properly preparing the pipe and fitting, apply flux to the joint to promote adhesion of the solder.
-
Heat the Fitting: Use a propane torch, directing the flame towards the middle of the fitting.
-
Wait for Bubbling: Observe the flux. The bubbling of the flux indicates that the fitting is heating up.
-
Apply Solder: Once the fitting is hot enough (indicated by the bubbling flux and the fitting changing color), touch the solder to the joint between the pipe and the fitting. If the fitting is hot enough, the solder will melt and be drawn into the joint via capillary action.
-
Spread the Solder: Continue applying solder around the entire joint, ensuring complete coverage.
