An angle stop, also known as a stop valve or shut-off valve, is a crucial component of your plumbing system. It's a small valve usually located behind the fixture (sink, toilet, etc.) that allows you to easily shut off the water supply to that specific fixture without affecting the rest of your home's water system. Understanding its function and potential problems is key to maintaining a smoothly running household.
What Does an Angle Stop Look Like?
Angle stops typically have a compact, angled design, hence their name. They are usually brass or chrome-plated brass, and feature a small handle that you turn to control the water flow. The angle design allows for a more compact installation, especially in tight spaces under sinks. You’ll typically find them with either a compression fitting or a solder connection to the supply line.
What are the Different Types of Angle Stops?
While most angle stops share a similar function and basic design, you’ll encounter a few variations:
- Compression Angle Stops: These are the most common type. They use compression fittings to connect to the water supply lines and the fixture. This makes them relatively easy to install and replace.
- Soldered Angle Stops: These angle stops are soldered directly onto the water supply lines. This offers a more permanent, leak-resistant connection, but requires plumbing skills and a soldering iron to install or replace.
- Different Handle Types: You might find angle stops with different handle types, such as lever handles, or older style screw-type handles. The function remains the same, but the operation varies slightly.
How Does an Angle Stop Work?
An angle stop functions as a simple on/off valve. Inside the valve body is a mechanism that restricts or allows water flow. When you turn the handle, this mechanism either opens the pathway for water to flow to your fixture or closes it off completely. This simple mechanism is extremely effective in controlling water flow to individual fixtures.
Why is an Angle Stop Important?
The importance of angle stops often becomes apparent when you need to repair or replace a fixture. Without an angle stop, you would have to shut off the main water supply to the entire house to perform even a minor repair, which is far less convenient. Angle stops provide:
- Convenience: Easily shut off water to individual fixtures for repairs or maintenance.
- Water Saving: Prevents significant water wastage during repairs.
- Protection: Isolates affected plumbing issues, minimizing disruption to the rest of the home's water supply.
How Do I Know if My Angle Stop is Leaking?
A leaking angle stop is a common issue that can lead to higher water bills and potential water damage. Signs of a leaking angle stop include:
- Visible water dripping: Look for moisture around the valve.
- Dampness under the sink: This indicates a leak that may not be immediately visible.
- Unexplained rise in your water bill: A consistent increase without other explanations can point to a leak.
How Do I Replace a Leaky Angle Stop?
Replacing a leaky angle stop is a relatively straightforward DIY project for those comfortable with basic plumbing. If you are not comfortable, it's best to call a professional plumber. The process typically involves turning off the main water supply, disconnecting the old angle stop, and then installing a new one.
What are Some Common Problems with Angle Stops?
Besides leaks, here are other issues you might encounter:
- Corrosion: Over time, mineral build-up and corrosion can affect the valve's functionality, leading to leaks or stiff operation.
- Handle Failure: The handle itself can break or become difficult to turn due to wear and tear.
- Improper Installation: Faulty installation can result in leaks and other problems.
Understanding the function and maintenance of angle stops is crucial for maintaining your home's plumbing system. Regular inspection and timely replacement can prevent costly water damage and disruption to your daily life.
