Pipe Cutters: Tools designed to cut through different types of pipes, including copper, PVC, and PEX. Pipe cutters provide a clean, straight cut, essential for accurate fitting.
Soldering Torch: A tool used to Solder copper pipes and fittings, creating watertight joints. The torch heats the metal to melt solder, which flows into the joint and solidifies to form a strong bond.
Pipe Threader: A tool used to cut threads into the ends of metal pipes, allowing them to be screwed together with fittings. Pipe threading is commonly used in gas and water supply lines.
Plumbing Inspection Camera: A small camera attached to a flexible cable, used to inspect the interior of pipes and drains. The camera provides a visual of blockages, leaks, or damage within the plumbing system.
Plumbing Tape (Teflon Tape): A thin, white tape used to seal threaded connections in plumbing systems. Plumbing tape helps prevent leaks by creating a tight seal between the threads.
Plumbing Level: A tool used to ensure that pipes and fixtures are installed level and straight. Maintaining proper alignment is critical for the functionality and appearance of plumbing systems.
Plumbing Hammer (Ball-Peen Hammer): A hammer used to shape metal pipes, fittings, and other materials. The ball-peen hammer is particularly useful for tasks that require shaping or bending metal.
Plumbing Pressure Gauge: A device used to measure water pressure within a plumbing system. Maintaining proper pressure is important for preventing leaks, bursts, and ensuring the efficient operation of fixtures.
4. Common Terms Used by Plumbers
Understanding the terminology used by plumbers can help homeowners communicate more effectively and understand the processes involved in their project. Common terms include:
Backflow: The reverse flow of water or other substances into the potable water supply, typically due to a drop in pressure. Backflow prevention devices are installed to prevent contamination.
Drain-Waste-Vent (DWV) System: The system of pipes that carries waste and sewage away from the home and vents sewer gases to the outside. The DWV system is essential for maintaining proper drainage and preventing sewer gas buildup.
Fixture: Any plumbing device that uses water, such as a Sink, Toilet, bathtub, or Shower. Fixtures are connected to both the water supply and drainage systems.
Flange: A flat, circular piece that connects a pipe to a fixture or another pipe. Flanges are commonly used in toilet installations and are essential for creating a secure, leak-free connection.
GPM (Gallons Per Minute): A measurement of water Flow Rate, typically used to describe the flow capacity of faucets, showerheads, and other fixtures.
Gray Water: Wastewater generated from household activities such as washing dishes, laundry, and bathing. Gray water can be reused for irrigation or flushing toilets, but it requires proper treatment and handling.
Pressure Reducing Valve (PRV): A valve installed in the water Supply Line to reduce the incoming water pressure to a safe level for the home’s plumbing system. PRVs are essential for preventing damage to pipes and fixtures.
