What’s a Check Valve for a Sprinkler System?

Automated sprinkler systems keep your yard irrigated and save a lot of time and hassle — but they’re also complex and made up of many components. Getting familiar with your sprinkler system is essential, whether you’re troubleshooting an issue or just trying to learn more about how it works. One of the most important parts of any irrigation system is the sprinkler pump check valve. This critical component plays a key role in regulating water flow, protecting your potable water supply, and maintaining optimal system efficiency.

What’s a Check Valve for a Sprinkler System?

What’s the Purpose of a Sprinkler Head Check Valve?

Many commercial and residential sprinkler systems are equipped with a check valve, although some systems only have backflow preventers. These valves can be installed individually or in groups. Besides ensuring your sprinkler system works well, check valves also give users more control over the flow of water.

Controlling Water Flow

Your sprinkler system’s check valve is located between the sprinkler head and your water supply. Like all one-way valves, this check valve is designed to allow flow from one direction, while blocking water from heading in the opposite direction.

Protecting the Irrigation System

In short, sprinkler head check valves exist to prevent backflow — or to stop potentially dirty or contaminated water from heading back to your potable water supply, whether your sprinkler system is turned on or off. Check valves work to ensure that the sprinkler system turns off when the water pressure fluctuates or the direction of the flow of water is changed, preventing damage to your irrigation system.

A sprinkler system’s check valves can also be adjusted. This allows users to regulate the amount of water that can flow out of the sprinkler system, sometimes resulting in significant savings while still providing sufficient irrigation.

Common Issues with Check Valves in Sprinkler Systems

Sprinkler systems, including those installed throughout Omaha, can encounter several issues related to check valves. Here are the most frequent problems and their typical causes:

1. The valve won’t turn on

This may be caused by lacking water supply, a faulty timer, or a broken sprinkler solenoid. The valve may also manually have been turned off, in which case it simply needs to be opened.

2. The valve won’t turn off

In this case, disconnected wires are usually the culprit. The valve may also need to be cleaned.

3. A valve is leaking

This is usually caused by a damaged diaphragm.

4. The sprinkler’s spray isn’t sufficient

Adjusting the sprinkler system settings usually fixes the problem.

5. The sprinkler’s spray is excessive

Turn the flow down if the sprinkler spray is excessive.

Locating the Sprinkler Pump Check Valve

Understanding the sprinkler pump check valve location can make a big difference when diagnosing system issues or performing routine maintenance. In most systems, check valves are placed underground between the sprinkler head and the water supply. Identifying the exact placement may require following the main irrigation lines or consulting with a professional. This knowledge can help resolve backflow issues, ensure proper water pressure, and prevent damage to other system components.

Benefits of Using a Check Valve for Sprinkler Systems

A check valve for a sprinkler system offers several advantages:

  • Backflow Prevention: Protects potable water from contamination.
  • Improved Efficiency: Maintains consistent water flow for optimal irrigation.
  • Adjustable Control: Allows customization of water output to save resources.
  • System Longevity: Reduces wear and tear on the system by managing pressure changes effectively.

Maintenance Tips for Check Valves

Regular maintenance is key to keeping your sprinkler system’s check valve in top condition. Inspect for debris or blockages, ensure the valve opens and closes properly, and address any leaks promptly. Scheduling routine checks with a professional can also help identify potential issues before they escalate.

Improving Your Irrigation System’s Efficiency
Check valves aren’t the only critical components of an irrigation system. Additional steps can further improve efficiency and water conservation:

  • Sprinkler valve placement adjustments to balance water output.
  • Automatic irrigation system settings to manage watering schedules efficiently.
  • Sprinkler backflow prevention devices to enhance system safety and performance.
  • Seasonal maintenance, including sprinkler winterization in Omaha, to protect the system during colder months.
