Types Of Water Shut Off Valve
It is important to know the different types of shut off valve when selecting the right one for your home's plumbing needs. Each type has unique features and benefits, suited for various applications.
Gate Valve
A gate valve is a type of water shut off valve that uses a metal gate to control the flow of water. This gate is lifted or lowered by turning a wheel handle, which makes it easy to see whether the valve is open or closed. Gate valves are commonly used as a main water shut off valve because they provide a reliable seal but are generally recommended for situations where they are not frequently turned on and off. They are best used where steady, uninterrupted flow is needed.
Ball Valve
Ball valves are another popular type of shut off valve that offers excellent durability and control. They use a rotary ball with a hole through the center, which aligns with the water flow when open and blocks it when closed. Ball valves are known for their longevity and quick shut-off capabilities, making them ideal for both indoor and outside water shut off valve applications where quick, reliable operation is essential.
Angled Shutoff Valve
The angled fixture shutoff valve is specifically designed for tight spaces where pipes enter a room at an angle. This type of shut off valve bends at an angle, which allows it to fit in places where a straight valve cannot. They are commonly used under sinks and toilets and provide an easy and effective way to control water flow to individual fixtures. Angled valves are particularly helpful in managing water flow in bathroom or kitchen remodels.
Straight Shutoff Valve
Straight fixture shutoff valves are the simplest form of water shut off valve, designed for straightforward, direct line applications. These valves are most commonly used where the water pipe enters a fixture directly from the wall. Because of their simple design, they are easy to install and maintain, making them a popular choice for internal plumbing systems. Straight valves are essential for controlling the flow to specific areas without affecting the entire system.
Which Direction Do You Turn A Water Shut Off Valve?
The direction to turn a water shut off valve often depends on its type. Here's how to operate each kind:
- Gate Valve: To close the gate valve, turn the wheel handle clockwise; turn it counterclockwise to open it. This action lowers or raises the gate to stop or start water flow.
- Ball Valve: Rotate the handle of a ball valve 90 degrees clockwise to shut off the water. To open it, simply turn the handle 90 degrees counterclockwise.
- Angled Shutoff Valve: Similar to other valves, turn the handle clockwise to close and counterclockwise to open this type of shut off valve.
- Straight Shutoff Valve: For straight fixture shutoff valves, turning the handle clockwise will stop the water flow, and turning it counterclockwise will allow water to pass through.
These directions ensure proper operation of the valves, whether they are used indoors or as an outside water shut off valve.
Buying Guide
When choosing the right water shut off valve for your home, consider these crucial factors to ensure compatibility, ease of installation, and durability.
Material
The material of a water shut off valve plays a significant role in its durability and suitability for specific environments. Valves made from brass or stainless steel are resistant to corrosion and can be ideal for both indoor and outside water shut off valve applications. Plastic valves may be more cost-effective and are resistant to chemical degradation, making them suitable for treated water applications.
Type Of Valve
Selecting the type of shut off valve depends on your specific needs, such as frequency of use and required flow control. Ball valves are best for applications requiring frequent operation, while gate valves are suited for infrequent use but offer a tight seal. Consider an automatic water shut off valve for enhanced protection against leaks and water damage, especially in high-risk areas.
Size
The size of the water shut off valve should match the diameter of your existing plumbing pipes to ensure a leak-free installation and efficient water flow. It’s crucial to measure your pipes accurately or consult with a professional before purchasing a valve to avoid compatibility issues.
Pipe Compatibility
Ensure that the shut off valve you choose is compatible with the type of piping in your home. Some valves are specifically designed for copper, PVC, or PEX pipes, and using the wrong type can lead to improper fitting or even damage to the piping system. Compatibility is particularly important for outside water shut off valve setups where environmental factors might influence material choice.
Installation
Installation ease can vary greatly between different types of water shut off valves. Some valves may require professional installation, especially in complex plumbing systems or where major pipe modifications are necessary. For simpler setups, look for valves that offer straightforward, tool-free installations, particularly if you plan to install the valve yourself.
