Plumbing Terms Decoded: A Homeowner’s Guide to Industry Lingo

Hard Water

When water contains high levels of dissolved minerals like calcium and magnesium, it’s considered hard. Over time, hard water can cause corrosion, clogged fixtures, and reduced efficiency in appliances.

Water Softener

This device or substance treats hard water by reducing its mineral content. It protects plumbing fixtures, extends the life of appliances, and makes everyday tasks like bathing more pleasant.

Branch Drain

A branch drain is the pipe that collects wastewater directly from household fixtures like sinks, tubs, and toilets. It channels this water toward the main drainpipe, which connects to the municipal sewage system or a private septic tank.

Drain Field

A drain field is an underground system of pipes that works in tandem with a septic tank. It filters and disperses water into the soil, ensuring contaminants are minimized before reaching the groundwater.

Fittings

These essential plumbing components join two or more pipes together. Common examples include couplings, elbows, and tees, each serving a specific purpose in the system.

GPF (Gallons Per Flush)

GPF measures how much water a toilet uses per flush. Federal regulations mandate a maximum of 1.6 GPF for modern toilets, promoting water conservation without sacrificing performance.

Potable Water

Potable water refers to water safe for drinking and cooking. While modern plumbing systems no longer rely on storage pots, the term has endured as a standard in the industry.

Trap Seal

Every drain connecting to a sewer includes a curved pipe known as a trap. The trap seal is the water that sits in this curve, acting as a barrier against unpleasant odors from sewer gases.

Tee

A tee fitting features a T-shaped design that connects three pipes. Plumbers commonly use it to create branch lines in a drainage or water supply system.

Blow Bag

This tool clears clogged drains by sending pressurized bursts of water through the pipe. Equipped with a nozzle and bladder, a blow bag attaches to a standard garden hose for easy use.

Dope

Plumber’s dope, a thick paste-like sealant, ensures a leak-proof and pressure-tight connection between threaded pipes. It is often confused with plumber’s tape, which serves a similar purpose but differs in form and application.

Snake

A plumbing snake is a flexible metal coil used to break up tough clogs in drainpipes. Its spiral design allows it to navigate tight bends, making it indispensable for clearing stubborn blockages.
