Sprinkler Check Valves

Our sprinkler check valves are designed to automatically shut off when pressure reduces or changes direction, ensuring optimal performance and reliability in your irrigation system. Choose from our advanced inline spring valve and lead-free valve options, both meticulously crafted to provide superior flow control and longevity. Experience unmatched quality and peace of mind with our state-of-the-art check valves, the ultimate solution for maintaining a flawless irrigation setup.

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.

How Foot Valves Work

Foot valves function like a check valve, as they allow water to flow in one direction (into the pipe) while preventing backflow when the pump is turned off. When the pump starts, the foot valve will open up, allowing water to flow in. The valve remains open as long as the pump maintains suction, but as soon the pump stops, the foot valve closes automatically. Gravity would normally pull the water back down the pipe, but the foot valve traps water in the pipe, preventing backflow and keeping the pump primed for the next cycle.

Check Valve & Foot 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.

Where are foot valves commonly used?

Irrigation foot valves are typically used in wells, ponds, lakes, and other water sources where a pump draws water. These valves prevent water from draining back into the water system when the pump is turned off.

How long do foot valves last?

Brass or stainless steel foot valves can last 10 to 20 years, as they are durable and resistant to corrosion. High usage frequency and sediment, debris, and minerals in the water can cause increased wear over time. Regular cleaning and inspections help extend the lifespan.

What's the difference between a backflow preventer and a check valve?

For simple backflow prevention in a pump or well system, use a check valve. To protect drinking water from contamination, use a backflow preventer. A backflow preventer is a more advanced device designed to protect drinking water by completely stopping contaminated water from flowing backward into the main supply.
