What is an Angle Stop?
An angle stop, also known as an angle supply, is a type of shut-off valve commonly used in residential and commercial plumbing systems. It connects the water supply pipes within the wall to external fixtures such as faucets, toilets, and dishwashers. This valve allows for the localized control of water flow, enabling maintenance or emergency shut-off without disrupting the entire household’s water supply.
Key Characteristics of Angle Stops
- Design: Typically L-shaped (hence the name “angle”), allowing it to fit neatly where water lines emerge from the wall.
- Control: Provides easy access to shut off the water supply to a specific fixture, making repairs and replacements more convenient.
- Material: Commonly made from brass or other corrosion-resistant materials to ensure durability and longevity.
Benefits of Using Angle Stops
- Localized Shut-Off: Enables water supply to be cut off to individual fixtures without affecting the rest of the plumbing system.
- Easy Maintenance: Facilitates easy maintenance and repair of faucets, toilets, and other fixtures by allowing the water to be shut off right at the source.
- Leak Prevention: Helps prevent water damage during emergencies by quickly shutting off the water supply to a leaking fixture.
Installation and Usage
Installation Steps
- Shut Off Main Water Supply: Before installing an angle stop, ensure the main water supply is turned off.
- Attach to Supply Line: Connect the angle stop valve to the water supply pipe emerging from the wall.
- Secure the Fixture Connection: Attach the fixture’s supply line to the angle stop valve.
- Check for Leaks: Once installed, turn the main water supply back on and check the connections for any leaks.
Practical Usage
- Under Sinks: Commonly installed under kitchen and bathroom sinks to control water flow to faucets.
- Toilets: Installed behind toilets to manage water supply to the tank.
- Appliances: Used to control water supply to appliances like dishwashers and washing machines.
Real-Life Applications
Example Scenario: A homeowner notices a leak in the kitchen faucet. Instead of shutting off the water to the entire house, they can simply turn the angle stop valve located under the sink to stop the water flow to the faucet. This allows them to repair or replace the faucet without affecting other water fixtures in the home.
