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. You may want to get more familiar with your sprinkler system because something went wrong, and you’re hoping to do some troubleshooting that may lead to an easy fix, or you may also simply want to get to know your sprinkler system a little better. In either case, the check valve that your sprinkler system is equipped with is one of its most vital components. But, what is a check valve?

What’s a Check Valve for a Sprinkler System?

What’s the Purpose of a 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.

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.

In short, 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.

What Can Go Wrong with Check Valves?

A sprinkler system’s check valves can be affected by a number of different problems. Let’s take a look at the five most common issues with check valves and sprinkler systems:

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.
