What Is An Angle Stop?

Are you curious to know what is an angle stop? You have come to the right place as I am going to tell you everything about an angle stop in a very simple explanation. Without further discussion let’s begin to know what is an angle stop?

In the intricate network of plumbing systems, small but crucial components often go unnoticed until the need arises. One such unsung hero of plumbing is the angle stop valve. This unassuming device plays a vital role in controlling the flow of water to specific fixtures, providing convenience and functionality in both residential and commercial settings. In this blog post, we’ll delve into what an angle stop is, its purpose, installation, and why it’s an essential part of any plumbing system.

What Is An Angle Stop?

An angle stop valve, also known as an angle stop or simply a stop valve, is a plumbing fixture that controls the flow of water to a specific plumbing fixture or appliance, such as a faucet or toilet. It is typically located at the point where water supply lines meet individual fixtures, allowing for easy shut-off when maintenance, repairs, or fixture replacement is necessary.

Key Components Of An Angle Stop:

  • Handle:

The angle stop valve features a handle that can be turned to control the flow of water. When the handle is turned clockwise, the valve closes, stopping the water flow. Conversely, turning the handle counterclockwise opens the valve, allowing water to flow through.

  • Inlet and Outlet Connections:

Angle stops have distinct inlet and outlet connections. The inlet is connected to the main water supply line, while the outlet is connected to the water supply line leading to the specific fixture.

  • Compression Nut and Ferrule:

Many angle stops utilize a compression fitting to connect to the water supply line. The compression nut and ferrule create a watertight seal when tightened onto the supply line, preventing leaks.

Purposes And Applications:

  • Fixture Shut-Off:

The primary purpose of an angle stop is to provide a convenient shut-off point for individual fixtures. In the event of a plumbing issue or the need for fixture replacement, the angle stop allows for localized control without disrupting the entire water supply.

  • Maintenance and Repairs:

Angle stops facilitate maintenance and repairs by allowing plumbers or homeowners to isolate specific fixtures without affecting the water supply to the entire building. This targeted shut-off capability streamlines the repair process.

  • Fixture Replacement:

When replacing faucets, toilets, or other fixtures, the angle stop enables a hassle-free process. Turning off the valve isolates the water supply to the fixture being replaced, minimizing water wastage and ensuring a more efficient installation.

Installation Process:

  • Locate the Fixture’s Angle Stop:

Before beginning any installation or maintenance, locate the angle stop associated with the fixture. Angle stops are commonly found beneath sinks, behind toilets, or near other fixtures.

  • Turn Off the Main Water Supply:

For safety, turn off the main water supply to the building before working on any plumbing fixtures. This ensures that water flow is completely halted during the installation or maintenance process.

  • Disconnect the Supply Line:

If replacing an existing angle stop, use an adjustable wrench to disconnect the supply line from the old valve. If installing a new angle stop, ensure that the supply line is cut to the appropriate length and attach the compression nut and ferrule.

  • Attach the New Angle Stop:

Connect the new angle stop to the supply line and hand-tighten the compression nut. Use an adjustable wrench to secure the connection, ensuring a snug fit without over-tightening.

  • Turn On the Water Supply:

Once the angle stop is securely in place, turn on the main water supply. Slowly open the angle stop valve by turning the handle counterclockwise, allowing water to flow to the connected fixture.

Conclusion:

While often overlooked, the angle stop valve is an essential component in the world of plumbing, providing a simple yet effective means of controlling water flow to individual fixtures. Its ability to isolate specific areas of a plumbing system makes it a valuable asset during maintenance, repairs, and fixture replacements. As plumbing systems continue to evolve, the humble angle stop remains a reliable and indispensable tool, ensuring the smooth functioning of water supply in homes and businesses alike.

FAQ

What Is An Angle Stop Used For?

A quarter turn of the handle on an angle valve will quickly shut off the water being supplied to a fixture and help prevent an overflow. This allows repair work to be performed without interrupting water flow to other areas.

How Long Does An Angle Stop Last?

Older angle stop valves, normally called 1-piece angle stop valves, were never designed to last. After 8-10 years OR EVEN JUST ONE USE AFTER INSTALLATION, the compression part of the valve, that actually stops the water, tends to fail.

What Is The Difference Between Straight Stop And Angle Stop?

On a straight stop valve, the inlet and outlet are aligned. Straight valves are typically found where the supply line comes through the floor. On an angle valve, the outlet is at a 90-degree angle from the supply line. Angle valves are used on supply lines that come from the wall.

What Size Is Angle Stop?

Angle or straight stops have an inlet that is either 1/2″ fip (female iron pipe) or 5/8″ o.d. copper compression. The 1/2″ fip stops are for attaching to threaded pipe nipples.
