An angle stop is a small, usually brass valve that controls the water supply to individual fixtures in your home, such as sinks, toilets, and washing machines. It's strategically placed where the water supply pipe meets the fixture's supply line, often tucked away behind the fixture or within the wall. Understanding its function and importance is crucial for homeowners, plumbers, and DIY enthusiasts alike.
What Does an Angle Stop Do?
The primary function of an angle stop is to shut off the water supply to a specific fixture. This is incredibly useful for repairs or replacements. Instead of turning off the entire house's water supply, you can simply turn off the angle stop valve, isolating the affected fixture. This saves time, prevents water damage, and minimizes disruption to your household. Beyond repairs, angle stops are also crucial for:
- Preventing Leaks: If a leak develops within a fixture's supply line, the angle stop allows you to quickly isolate the leak and prevent further water damage.
- Maintenance: Easy shut-off enables easier maintenance and cleaning of fixtures without affecting the rest of your plumbing system.
- Fixture Replacement: Before replacing a faucet or toilet, turning off the corresponding angle stop protects against flooding during the process.
What are the Different Types of Angle Stops?
Angle stops come in various types, primarily differing in their operation and material:
- Compression Angle Stops: These are the most common type, featuring a compression nut that squeezes a rubber washer against the valve seat to shut off the water flow. They are relatively inexpensive and easy to repair or replace.
- Ball Angle Stops: These use a ball valve mechanism for a quicker, more positive shut-off. They are often favored for their durability and smoother operation.
- Material: Most angle stops are made of brass, known for its durability and resistance to corrosion. However, you might find some made from other materials like plastic, although these are less common and generally less durable.
How Do I Identify an Angle Stop?
Angle stops are usually small and inconspicuous, but you can typically find them:
- Behind the sink: Often located under the sink, near where the water supply lines connect to the faucet.
- Behind the toilet: Usually positioned behind the toilet tank, near the water supply line.
- Behind the washing machine: Situated where the water supply lines connect to the washing machine.
They usually have a small handle or knob that you turn to shut off the water.
How Do I Turn Off an Angle Stop?
Turning off an angle stop is typically straightforward:
- Locate the handle: Find the small handle or knob on the angle stop.
- Turn clockwise: Turn the handle clockwise to shut off the water supply. A quarter turn is often sufficient.
- Check for leakage: After turning the angle stop off, carefully check for any leaks around the valve.
What Happens if My Angle Stop Leaks?
A leaking angle stop is a sign that it's likely worn out or damaged and needs repair or replacement. Ignoring a leak can lead to significant water damage and higher water bills. Repairing or replacing a leaking angle stop is often a relatively simple DIY project, but if you're uncomfortable working with plumbing, it's best to call a qualified plumber.
Can I Replace an Angle Stop Myself?
Yes, replacing an angle stop is often a DIY-friendly project for homeowners with some basic plumbing skills. However, always turn off the main water supply before attempting any plumbing repair. If you're unsure about any step, it’s best to consult a professional plumber to avoid any potential problems.
What Size Angle Stop Do I Need?
Angle stops typically come in standard sizes that match your plumbing system (½ inch or ¾ inch are common). It's best to check the size of your existing angle stop before purchasing a replacement to ensure compatibility. Measuring the existing pipe diameter will confirm the correct size.
This comprehensive guide should provide you with a thorough understanding of angle stops. Remember, regular inspection and timely maintenance can help prevent costly repairs and water damage.
