You can find brass shut off valves throughout your entire home. Brass is the material of choice due to its durability and reliability in residential plumbing systems. The most popular material for water shut of valves is brass. Older homes with galvanized steel piping will have the water shut off valves screwed on to threaded pipe sections. Shut off valves on CPVC water lines are usually threaded, push to connect, or solvent cemented in place. You can check out our tutorial on solder copper here.Ĭhlorinated Polyvinyl Chloride or CPVC pipe is a strong and flexible plumbing material. Soldering copper is a great method of installation but requires extra plumbing tools and supplies. Compression fittings can also be found on PEX waterlines, which are installed with some basic hand tools.Ĭopper supply lines allow for the use of the same shut off valves as PEX with the addition of solder/sweat-on fittings. They can also use push-to-connect (also known as Sharkbite) fittings which bite down and compress an o-ring to create a water-tight seal. PEX water lines can use shut off valves that are barbed and are crimped in place with a special crimp ring and tool. How you connect water shut off valves to your water lines depends on the material your pipes are made of. How Are Shut Off Valves Connected To Water Lines? You will find angled shut off valves at your laundry machine or where water lines extend out from a wall. You will typically find straight shut off valves on long sections of water pipes and where water lines come up through the floor to supply water to a plumbing fixture.Īngled shut off valves are positioned so that the inlet and outlet of the valve are at a 90°. Straight shut off valves are oriented so that the inlet and outlet of the valve are aligned and pointing in the same direction. Water shut off valves typically come in two configurations: straight and angled. What Kinds Of Water Shut Off Valves Are There? Whereas multi-turn valves are cheaper they typically require maintenance to keep them leak-free and functioning properly. In our experience, quarter-turn valves are more expensive than multi-turn valves but tend to be more reliable.
Conversely, when the handle is turned perpendicular to the valve the steel ball twists and STOPS the flow of water. If the handle is in-line with the valve body, the valve is OPEN and water flows through the hole in the steel ball. Alternatively, counter-clockwise will OPEN the valve and allow water to pass through the valve.īall valves or quarter-turn valves operate via a handle on the valve stem that pivots a steel ball with a hole inside to control the flow of water. Turning the handle clockwise will tighten the valve stem inside and force a gate CLOSED or press a rubber gasket against a seat to restrict the flow of water. Shut off valves with a wheel or other multi-turn valves operate by spinning the handle. Think of this like the difference between a shut off valve for your toilet that is normally open and your outside hose bib that is normally closed. As a result, a shut off valve can isolate a plumbing fixture from the rest of the plumbing in your home or hold water back until you need it. Water shut off valves are designed to stop the flow of water. Going into details like what valves are used for, what they are made of, and where you find them inside and outside your home. Our guide will walk you through the main water shut off valve through to fixture valves and everything in between.
And it can be confusing to tell what each valve controls and how it operates. You will have several different types of water shut off valves that regulate the flow of water in your home. By Trevor Woods | Last Updated: August 1, 2020
