Shut Off Valve vs Check Valve

Shut Off Valve vs Check Valve – What’s the Difference

Plumbing issues can be a nightmare, especially when dealing with water damage or a high water bill. It’s essential to understand the different valves available to prevent such issues. Two popular types of valves are shut-off valves and check valves. However, many people need clarification about their differences and when to use them. This blog post discusses the critical differences between shut-off and check valves and which one you should choose for your plumbing needs.

What is Shut Off Valve?

A shut-off valve is a valve that is used to stop the flow of water in a pipe. It is usually placed near the plumbing fixture or the appliance it controls. Most shut-off valves are made of brass, copper, or plastic. Shut-off valves are available in different types, such as gate, globe, and ball valves. Gate valves are the most common type of shut-off valves. They are inexpensive and easy to operate. However, they tend to leak over time and cause water damage. Globe valves are more reliable than gate valves but are more challenging to manage. Ball valves are the most popular type of shut-off valve. They are easy to install and can be used with one hand. They also offer reliable and long-lasting performance.

What is Check Valve?

A check valve is a valve that allows water to flow in only one direction. It is usually placed in vertical pipes to prevent backflow and flooding. Check valves are commonly used in sump pumps, irrigation, and sewage systems. Check valves come in different types, such as swing, tilting disc, and spring-loaded check valves. Swing check valves are the most popular type of check valve. They are easy to install and require minimal maintenance. Tilting disc check valves are more reliable than swing check valves but are more expensive. Spring-loaded check valves are the most reliable type of check valve and the most costly.

Shut-off valves are best used to control water flow, such as under sinks, near toilets, and appliances that use water, such as dishwashers and washing machines. Shut-off valves should be used when you need to quickly shut off the water supply.

Use the Check valve

Check valves, such as sump pumps, irrigation, and sewage systems, are best used when backflow can occur. Check valves to prevent water from flowing back into the system, causing damage. Check valves should be used in situations where preventing backflow is essential.
