Water supply stop valves, also known as shut-off valves, are an integral part of our plumbing systems. They provide an easy and convenient way to control the flow of water in a variety of applications. Without them, managing water flow during repairs, installation, and emergencies would be a challenging endeavor. This article aims to shed light on what water supply stop valves are, how they function, where they’re utilized, and the various types available, with special emphasis on Easyflex water supply stop valves.

What are Water Supply Stop Valves?

A water supply stop valve is a device that regulates the flow of water through pipes. It allows for the complete stoppage of water supply when needed, or adjustment of the water flow. These valves are typically installed in strategic locations where water control is necessary – such as before appliances or fixtures. Their primary function is to isolate specific parts of a plumbing system, allowing for repairs or replacement without needing to shut down the entire water supply.

How Do They Work?

Water supply stop valves work on a simple principle: the manipulation of the internal mechanism, usually a ball or a gate, to either stop or allow the flow of water. When the valve is turned in one direction, usually clockwise, the mechanism obstructs the pipe, preventing water flow. When turned in the other direction, it moves out of the way, allowing water to pass.

The action of turning the valve is usually done manually via a wheel or a lever. However, there are advanced stop valves that come equipped with automatic features like sensors that trigger the valve in the event of leaks.

Where Are They Used?

Water supply stop valves are used throughout residential, commercial, and industrial plumbing systems. In homes, you’ll commonly find them on water lines leading to sinks, toilets, washing machines, water heaters, and outdoor spigots. They are essential in these places for easy repair and maintenance, and in the case of a sudden leak, to quickly stop the water flow and prevent water damage.

In commercial and industrial settings, they are used on a larger scale, installed in places such as main water supply lines, HVAC systems, and large appliances.

Different Types of Water Supply Stop Valves

There are various types of water supply stop valves, each best suited for different applications:

• Ball Valve: A large metal valve with a lever handle, designed to quickly turn off water. They are usually used for main water pipes and are recognized for their thick middle section, which houses the internal ball. The ball, with a hole through its center, allows water to flow when opened and blocks it when closed.

• Gate Valve: A valve that uses a gate mechanism, raised, or lowered by a circular handle, to control water flow. They’re suitable for main water pipes, and while not common in residential settings, you might find them controlling major water pipes or leading to a hot water boiler.

• Globe Valve: Recognized by its slightly bulbous metal body, a globe valve contains a baffle with a water flow port running through it. The handle operates a plunger that closes off the water flow port when the valve is closed. These valves are used where water flow might need to be variably controlled, such as in water spigots or plumbing line branches.

• Angled Fixture Shutoff Valve: Primarily used when a water pipe comes out of the wall and needs to angle straight upward to feed supply tubes. These valves are small, silver, with an oval handle, and are common in homes for controlling water supply to individual fixtures.

• Straight Fixture Shutoff Valve: Similar to the angled fixture shutoff, this valve is designed for use where the water flow can run straight to the fixture. These are often used where a water pipe comes up out of the floor rather than out from the wall.

• Stop-and-Waste Valve: This type of valve is essential for keeping sprinkler lines from freezing in the winter. The valve has two openings: one to control the water flow and the other to allow water to drain from the line. It’s typically buried in the ground below the freeze line for sprinkler systems.

• Needle Valve: Usually used to connect a water supply tube to an appliance, such as a refrigerator or water filter. However, many building codes no longer permit their use, as they are not regarded as very reliable or durable.
