What Is an Angle Stop Valve?

There are many valves that need to be used for connecting new water lines. This makes plumbing complicated. Many basic plumbing tasks can be done by homeowners in their bathrooms and kitchens. They need to be able to recognize the part by its appearance, and then use that information to order the correct replacements or troubleshoot issues. Learn what an angle stop valve is, how it looks, and how you can replace it.

The Stop Valve's Value

Stop valves are also known as shut-off valves and are used to turn off one appliance or fixture. A stop valve is installed to prevent a homeowner from having to switch off the main supply valve if the fixture leaks or sprays uncontrollably. While the problem is being fixed, the family can continue to use all other fixtures that are working. Each major water-using fixture, including the bathroom faucet and washing machine, must have an accessible stop valve.

What Is the Difference Between an Angle Stop Valve and a Straight Model?

The stub-out location for the water supply line is located in the bathroom. Angle stop valves are required for supply lines that are installed in the wall. The valve must connect to the pipes running through it -- providing the angle necessary to direct water towards the fixture. For fixtures that have supply pipes running directly through the floor, straight stop valves will work. There are many options for angle stop valves, including double-handle and three-way angle stops that can control multiple fixtures.

Do not wait for an angle stop valve to fail in one position or leak to replace it. This valve is used only in emergency situations so it is important to keep it functioning properly. These valves only last for about a decade. Even when not in use, the internal components that hold back the water supply can wear down over time. A single-use, low-quality angle stop valve can often be damaged and needs to be replaced regularly. To ensure that the water is cut off when it's needed most, install a premium quarter-turn angle valve.
