Connect New Copper Piping and Solder

What happens here

This is a critical step where new copper piping is integrated. First, a pipe cutter is used to precisely cut segments of copper pipe to the required lengths. The cut ends are then reamed using a pipe reamer to remove any internal burrs that could restrict water flow or create turbulence. All pipe ends and fittings (such as 90-degree elbows) are thoroughly cleaned to ensure proper solder adhesion. Flux is applied to the exterior of the pipe ends and the interior of the fittings. A propane or MAPP gas torch is then used to heat the joints, and solder (typically lead-free for potable water) is applied, flowing into the heated joint to create a strong, watertight seal. Safety precautions, such as using a flame protector (an Oatey Flashtrap is shown) and having a spray bottle full of water nearby to extinguish any errant flames, are essential.

Goal: New sections of copper pipe and fittings are cut, prepared, and then expertly soldered to connect the new valve to the existing copper plumbing lines.
