Licensed, Insured, and Bonded

A license indicates that the plumber in question has passed the regulatory requirements of a governing body. If insured, the insurance should cover both injuries and damages while on the job. Being bonded tells you that the plumber is also covered for extenuating circumstances, such as theft or going out of business.


A flapper is the movable part of a toilet shut-off valve, which is used to prevent or stop the flow of water. It starts the flush cycle, and it closes when the tank is empty, so it’s allowed to refill.


An overflow is a type of drain that’s used to prevent the overfilling of a basin or other fixture. You may notice that your bathroom sink has a small hole or slit near the top. That’s the overflow. It’s designed to prevent flooding.


When a water fixture produces a lower or reduced flow compared to its expected behavior, that’s called a low-flow. This may be caused by stoppage, leakage, low pressure, or other issues.


This is a flexible rod that’s inserted into pipes. It can have a clearing or cutting implement on one end. The cutting attachment is used to remove roots or limbs. A clearing end is for removing clogs. A plumber’s snake is one example of an auger.

Float Valve

A float valve is used in your toilet to keep the tank from overfilling. It usually has a hollow ball that’s connected to the valve at one end. As the ball rises, the valve closes.

This is by no means an exhaustive list, but it should help you get started on expanding your plumbing vocabulary.
