Teaches 3 methods to solder and connect copper pipes including traditional soldering and push-fit fittings
Learn 3 methods to solder and connect copper pipes for plumbing repairs. Covers traditional soldering with propane/map gas, pre-soldered fittings, and push-fit connectors.
Get your torch (map gas preferred over propane for higher heat), lead-free solder, flux, pipe cleaner/brushes, pipe cutters, and emery cloth or sandpaper.
Use pipe cutters to make a clean cut. Snug the cutter on the pipe, turn it, and snug again repeatedly. Avoid over-tightening which can deform the pipe.
Use a pipe cleaner with wire teeth or 400 grit sandpaper. Clean both the outside of the pipe and inside of fittings until shiny. Use a wire brush for fitting interiors.
Apply flux to both cleaned surfaces using a brush. Cover all areas that will touch. Wear rubber gloves to prevent oil contamination from fingers.
Slide fittings onto pipe immediately. Heat the fitting at the joint (not the pipe) with your torch until hot enough. Touch solder to the opposite side and let capillary action pull it in.
For SharkBite-style fittings, simply push the pipe in until it locks. Mark the pipe to ensure full insertion. These require no soldering or tools.
Wipe joints clean with a wet rag. Pressurize the system with water to verify no leaks before closing walls.
