    Sample answer:

    Soldering:

    • Involves joining copper pipes using a solder alloy and flux.
    • Requires a torch or soldering iron to melt the solder and create a permanent bond.
    • Suitable for potable water, refrigerant, and gas lines.

    Brazing:

    • Similar to soldering but uses a higher melting point alloy (braze) and a higher temperature torch.
    • Creates strong, leak-proof joints for high-pressure applications.
    • Ideal for joining copper, steel, and stainless-steel pipes in gas and heating systems.

    Crimping:

    • Involves using specialized tools to compress metal rings or sleeves around pipe ends.
    • Creates a secure, vibration-resistant joint.
    • Suitable for copper, CPVC, and PEX pipes in plumbing and hydronic systems.

    Push-to-Connect Fittings:

    • Utilize flexible rubber or polymer gaskets that seal between the pipe and fitting when pushed together.
    • Requires no tools or glue.
