Do sprinkler valves need to be buried?
Valves can be grouped together in manifolds, or installed individually – and valves should always be buried inside a plastic irrigation valve box. Never bury a valve directly in the dirt.
Where should sprinkler valves be placed?
In newer lawn irrigation systems, the valves should be installed in valve boxes set into the earth. Often these are easily visible. In small yards, there is often a single valve box located near where the irrigation pipes enter the ground from the water source.
How many sprinkler valves do I need?
Count up the number of zones you have in your design. That is the number of irrigation valves you will need. In the example on page 8, we will need eight valves because we have eight zones. This will also affect the size timer you will need to buy.
How high do sprinkler valves need to be?
6 inches
The normal rule is at least 6 inches above the top of the highest sprinkler head, some brands say it must be 12 inches. If it isn’t higher, the built-in backflow preventer will not work. The anti-siphon valve will also spill water from the air vent if not installed higher than all the sprinklers or emitters.
What is the most reliable sprinkler valve?
The best overall pick—the Orbit Anti-Siphon Valve—is a quality choice for the vital job of protecting the home’s drinking water by preventing water from the sprinkler system from flowing into the home’s water supply pipes.
Can I connect 2 sprinkler valves together?

What size sprinkler valve should I use?
Deciding how large a valve should be depends on your system’s flow rate. 3/4-inch valves are ideal for most residential applications where the flow rate is around 8 to 10 gpm (gallons per minute). If the flow rate exceeds 15 gpm, you should use a 1-inch valve.
How do I know which sprinkler valve goes to which zone?
Mark each valve with a white paint marker to indicate a zone number that it operates. For future use, make a diagram of your sprinkler system on paper, showing the location of each valve box, each valve and the area it irrigates.
