Check valves are an incredible tool for your sprinkler system. They can help save you water, stop backflow and ultimately spare your wallet from any expensive costs associated with repairs due to any water damage caused by backflow.

But with so many different types of check valves available, how do you know which one is right for your specific needs?

We’ll break it down in this blog post and make sure that you have all the information you need to decide if a check valve is the best investment for your sprinkler system.

What Is A Check Valve?

A check valve is a device used in a sprinkler system that allows fluid to flow through it in only one direction. It prevents the flow of fluid from reversing its course, typically using either a ball or disc inside the valve body.

This prevents backflow and helps ensure against any issues related to water pressure or contamination. The size of the check valve depends on the size of the pipe.

Smaller pipes require smaller valves while larger pipes require larger valves – this will prevent any pressure build-up within the pipe itself.

Why Should You Use One?

Using a check valve on your sprinkler system ensures that water isn’t draining out when it’s not in use, saving you money as well as water. It also helps prevent potential damage caused by backflow, which can lead to costly repairs down the line if left unchecked.

In addition, having a check valve installed can help keep debris like dirt and leaves out of your system – maintaining cleanliness and minimizing potential problems further down the road.

Different Types of Check Valves

Not all check valves are created equal, and different types of check valves are used depending on the size of your sprinkler system. Here is a brief overview of some popular check valve types:

Swing-Check Valves:

These have an internal disc that swings open or closed when fluid flows through the pipe. The opening and closing actions are powered by the pressure differential between the upstream and downstream sides of the valve.

These valves work well in low-pressure systems where there isn’t much force behind the flow.

Wafer-Check Valves:

These use a lightweight disc that closes against a seat at the top of the valve when there is no backflow present in the line.

This type of valve works best in systems where pressure is uniform throughout and isn’t too high or too low.

Butterfly-Check Valves:

This type has a circular disc attached to a stem that rotates within two rubber seals to open or close off flow through the line.

This type of valve works great for applications where high-pressure levels may be present, as it can handle higher pressures than other types of valves.

How To Install A Check Valve On A Sprinkler System

Installing a check valve on your sprinkler system is relatively easy, although it does require some basic understanding of plumbing and irrigation systems.

First, you’ll need to determine what type of check valve you need based on your sprinkler system’s size and pressure requirements.

Once you have selected your preferred type, make sure that all pipes leading into the area where you will be installing the valve are disconnected from any other equipment or lines so that they don’t interfere with installation processes or cause any damage during operation later on down the road.

After disconnecting everything, simply attach one end of the pipe to each side of the valve before securing it into place with bolts and nuts provided by a hardware store or online supplier.

Finally, reconnect all pipes leading up to and away from this newly installed valve before testing out its function via manual operation or via an automated controller if necessary!

Conclusion:

Ultimately, understanding how a check valve works is essential for deciding whether or not it will fulfill its desired function for long-term success!

With so many different types available depending on both your size requirements as well as material construction, make sure to get one tailored just right for your needs so you don’t miss out on any benefits associated with having such an important part installed in your sprinkler system!

With these tips at hand, now you’re ready to start shopping around for the perfect tool for keeping everything running smoothly! Good luck!
