Types of Water Supply Valves

Understanding the types of water supply valves in your home is crucial. The main water shutoff valve and individual fixture shutoff valves play different roles in your plumbing system.

Main Water Shutoff Valve

The main water shutoff valve controls the flow of water from the main supply line into your home. There are two common types:

  • Gate Valve: This valve is older and may require several turns to shut off.
  • Ball Valve: Modern and easier to use, it shuts off with a simple quarter turn.

Individual Fixture Shutoff Valves

These valves are located near sinks, toilets, and appliances like dishwashers and washing machines. They allow you to shut the water to a specific fixture without shutting off the entire house.

Locating the Main Water Shutoff Valve

Finding the main water shutoff valve is essential for quickly turning off the water in an emergency.

Common Locations Inside and Outside the House

  • Inside: Typically found in basements, crawl spaces, or near the water heater.
  • Outside: Often located near the foundation of your house or close to the street.

Tools Needed

  • Wrench
  • Screwdriver
  • Flashlight

Steps to Turn Off the Main Water Supply

Knowing how to safely and effectively turn off the main water supply can prevent significant water damage.

Safety Precautions

  • Wear protective gear.
  • Ensure proper lighting in the work area.

Step-by-Step Instructions

  1. Locate the Main Valve: Check the basement, crawl space, or outside near the foundation.
  2. Turn the Valve: For a gate valve, turn the wheel clockwise until it stops. For a ball valve, turn the handle 90 degrees.
  3. Verify: Run a faucet inside your home to ensure the water is off.

Turning Off Individual Fixture Valves

Sometimes, you may only need to switch off the water to a specific fixture rather than the entire house.

Identifying Fixture Valves

  • Under Sinks: Usually located in the cabinet under the sink.
  • Behind Toilets: Found near the base of the toilet.
  • Near Appliances: Look behind or under appliances like dishwashers and washing machines.

Step-by-Step Instructions

  1. Locate the Valve: Identify the valve near the fixture.
  2. Turn the Valve: Rotate the valve handle clockwise until it stops.
  3. Test: Turn on the fixture to ensure the water is off.
