Water Shutoff Valves: Types and How to Choose

What is a Water Shutoff Valve?

A water shutoff valve is a device that allows you to turn off the water supply to a specific area or fixture in your home. This is useful for emergencies, repairs, or upgrades. Water shutoff valves are located at various points along water pipes throughout your plumbing system.

Types of Water Shutoff Valves

There are several types of water shutoff valves, each with its own unique design and function. Here are seven common types:

1. Ball Valve

Best for: Main water pipes
Description: A ball valve is a large metal valve with a lever handle. It has a ball inside that rotates to open or close the water flow. Ball valves are quick and easy to operate, making them ideal for main water shutoff applications.

2. Gate Valve

Best for: Main water pipes
Description: A gate valve has a metal gate that slides up or down to open or close the water flow. Gate valves can be used to completely stop water flow or to reduce it.

3. Globe Valve

Best for: Water spigots, plumbing line branches
Description: A globe valve has a rounded body and a baffle with a water flow port. A plunger with a washer or seal closes the water flow port when the handle is turned. Globe valves allow for variable flow control.

4. Angled Fixture Shutoff Valve

Best for: Individual fixtures
Description: An angled fixture shutoff valve is a small metal valve with an oval handle. It is used when a water pipe comes out of the wall and needs to angle upward to feed supply tubes to fixtures like sinks and toilets.

5. Straight Fixture Shutoff Valve

Best for: Individual fixtures
Description: A straight fixture shutoff valve is similar to an angled fixture shutoff valve, but it is used when the water pipe runs straight to the fixture.

6. Stop-and-Waste Valve

Best for: Sprinkler lines
Description: A stop-and-waste valve has two openings: one to open and close the water flow and one to allow water to drain from the line. This valve is used in sprinkler systems to prevent freezing in the winter.

7. Needle Valve

Best for: Water supply tubes
Description: A needle valve is a small valve that clamps onto a water pipe and uses a needle to tap the water. It is commonly used to connect water supply tubes to appliances like refrigerators and water filters.

Choosing the Right Water Shutoff Valve

When choosing a water shutoff valve, consider the following factors:

Flow control: Do you need to be able to partially or fully restrict the water flow? Ball valves are non-variable, while globe valves allow for variable flow.
Location: Consider the location of the valve and whether you need a straight or angled fixture valve.

Other Considerations

Durability: Different types of valves have varying levels of durability. Choose a valve that is appropriate for the intended use.
Cost: Water shutoff valves range in price. Determine your budget before making a purchase.
Installation: Some valves are easier to install than others. If you are not comfortable installing a valve yourself, it is best to consult a plumber.

When to Call a Plumber

If you are experiencing water leaks or other plumbing issues, it is important to call a plumber. A plumber can diagnose the problem and recommend the appropriate solution, which may include installing or replacing a water shutoff valve.
