What is angle stop?

An angle stop, also known as an angle valve or angle shut-off valve, is a type of valve used to control the flow of water or gas in a plumbing system. It is typically installed at the point where the water or gas supply pipe connects to a fixture or appliance, such as a toilet, sink, or washing machine.

Angle stops are designed to allow for convenient shut-off of the water or gas supply to a specific fixture or appliance, typically during repairs, maintenance, or emergency situations. They are often referred to as "stop" valves because of their ability to stop the flow of water or gas.

Angle stops are usually made of brass or other durable materials to ensure strength and durability. They usually have a lever or handle that can be turned to control the flow of water or gas. When the lever is in the open position, the supply line is open and allows water or gas to flow freely. When the lever is turned to the closed position, the supply line is shut off, stopping the flow.

There may be different types of angle stops available, depending on the specific plumbing system and the type of connection required. Common types include compression angle stops, which have a compression fitting for connecting to a pipe, and threaded angle stops, which have male or female threads for connecting to a threaded pipe or fitting.

Angle stops are often installed in accessible locations, such as under sinks or behind toilets, to allow for easy access and operation. They are typically labeled or color-coded to indicate which fixture or appliance they control, making it easier to identify and navigate the plumbing system.

Regular maintenance and periodic inspection of angle stops is important to ensure proper functioning and prevent leaks or malfunctions. If an angle stop fails or leaks, it should be replaced promptly to prevent further damage to the plumbing system.

Overall, angle stops are essential components in a plumbing system as they provide control and convenience in regulating the flow of water or gas to various fixtures and appliances.
