Signs That You Need a Check Valve

There are several common signs that indicate you might need sprinkler check valves in your irrigation system. For starters, if water continues to flow out of the lowest sprinkler heads after the system turns off, a valve will usually be necessary. Even if you can’t see your sprinklers leak, water might still collect in noticeable puddles near sprinklers, especially those on slopes or at the bottom of a hill. If you start to notice erosion, landscape damage, or general uneven watering, an irrigation check valve might be the simple solution.

Check Valve FAQs

What happens if I don't use irrigation check valves?

When the irrigation system shuts off, gravity causes water to drain out of sprinkler heads at the lowest points in the system. This wasted water puddles around sprinkler heads, oversaturating the soil and causing erosion. Frequent pressure fluctuations as the system starts up each time can also cause damage to the equipment.

Where are check valves installed?

Check valves are often placed strategically in systems with significant height differences. Check valves for irrigation systems will get the most value at low points in the system where water naturally collects. This will help maintain pressure and prevent water from draining downhill.

Do check valves prevent backflow?

Check valves are not a substitute for backflow preventers. They prevent water from draining out of sprinkler lines, but they do not protect against contamination of the water supply. A separate backflow prevention device is required for that purpose.
