Start at that sprinkler and try to find the valve nearby. The cheapest and easiest way to find buried irrigation valves is often to probe the soil with a thin rod, such as a long screwdriver. Often you can estimate the rough location of the irrigation valve, then find a buried valve box by probing the ground.
Will a metal detector find sprinkler valves?
A metal detector is unlikely to work because the valves are most likely to be plastic with very little metal in them. If you don't have any luck probing small low spots near the begining of the zone, it may require someone to do a wire trace for the valve.
How do you trace irrigation lines?
How to Find Sprinkler Lines Mark the Heads. Your sprinkler heads have to stick out of the ground or they won't work. Trace From the Valves. The sprinkler heads are not the only important part of mapping out the lines. Probing. After we have traced the lines to a place that needs work, we'll probe for components. Digging. .

How do you find out where your sprinkler lines are?
You can tell (roughly) where the pipes will be for that zone by finding the shortest path from the valve box that connects all the sprinklers in a zone. As long as you dig carefully, you shouldn't have too much trouble. The pipes are usually pretty tough and are usually buried about a foot or so under the ground.
How do I know if my sprinkler valves are open?
Turning it to the left lifts an internal gate that releases water incrementally as it turns. The gate lifts entirely when the handle is turned fully counterclockwise. If the handle will turn no farther counterclockwise, the valve is open.
How can I find my sprinkler lines without digging?
If you prefer to locate the lines and heads of your system without digging, rent a valve locator or even a metal detector and mark areas once found - better yet, call call 811, a federally mandated service, and ask someone to come out and locate the system for you.
Do all sprinkler systems have a master valve?
The irrigation controller turns the master valve on and off. Most, but not all, irrigation controllers have a master valve circuit built in to them.
How deep are sprinklers buried?
In most areas, burying the pipes 8 to 12 inches below the surface is adequate. This measurement is from the top of the pipe to the surface of the soil, which means your trenches must be slightly deeper to accommodate the pipes.
Does each sprinkler zone have a solenoid?
Related Articles. Sprinkler systems have valve controls for an area, or zone. Sprinkler valves have an electrical solenoid on top that receives a signal from the controller as to the time and duration of an irrigation schedule.
What are the three types of main sprinkler valves?
There are three basic types of valves used in irrigation systems – gate valves, ball valves, and electric valves.
How do you find underground PVC pipe?
PVC, or polyvinyl chloride, can be tricky to find because there is little or no metal in the pipe system, rendering a metal detector useless. Today, the best tool for the job is ground penetrating radar (GPR) as it accurately maps metal and PVC pipes.
How do I find sprinkler heads without water?
Pull a metal garden rake gently over the area of the grass where you suspect sprinkler heads are located if you cannot turn water on to the system. If the sprinkler heads are buried, you may need to apply greater pressure to the rake so it digs slightly into the soil.
Can you manually open sprinkler valves?
There are 2 simple methods to open the valve manually: To open the valve manually, twist the manual bleed screw counter-clockwise until the valve opens. It usually doesn't need to be more than one-half turn. To close the valve turn the manual bleed screw clockwise until the valve closes.
How do I turn on my main sprinkler valve?
Slowly open the main shutoff valve to let water into the sprinkler system. For a ball valve, turn the lever handle one-quarter turn until the handle is parallel to the pipe; this is the fully open position. For an in-ground shutoff valve, use a sprinkler valve key to turn the valve counterclockwise until it stops.
Are sprinkler valves normally closed?
For electronic solenoid valves – the most common type used in sprinkler systems these days – the nature of the valve means they're 'normally closed'.
How do you know if an irrigation valve is bad?
Signs of issues in sprinkler valve: Water not turning Off: If you notice that water is not closing off from the sprinkler, then there seems to be an issue in the diaphragm valve. Leaks of water: Broken Sprinkler Head. Stuck Valve. Wiring: Irregular Watering:..
Why won't my sprinklers turn on manually?
Here are some common reasons why your sprinkler system won't turn on: Lawn sprinkler control timer isn't working correctly. Clogged or dirty sprinkler heads. Broken sprinkler heads.
Where is a main sprinkler system valve usually installed?
In newer lawn irrigation systems, the valves should be installed in valve boxes. These can often be seen easily. There is a single valve box located near where the irrigation pipes enter the ground in small yards.
Should irrigation system have a master valve?
Without a master valve, once you turn the irrigation off those open sprinklers would continue to leak. With a master valve, turning off the irrigation would shut off the main water supply to the entire system and therefore those sprinklers could not leak.
What is an irrigation control valve?
Irrigation Control Valves: These are the valves that turn on and off the sprinklers, they also may be used for drip irrigation systems. Other names sometime used for them are irrigation valve, sprinkler valve, solenoid valve, and lawn valve. Sometimes they are incorrectly called Garden Valves.
Should irrigation valves 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.
How many sprinkler heads can you put on a zone?
If your home's water capacity was 10 GPM, you could place 3 heads per zone. Consult the Performance Charts on or inside the box your sprinkler head came in for your head's exact performance data, or locate the performance data in the Support area of this website.
How long can a sprinkler line be?
LENGTH OF RUN LIMITS: ½ inch tubing can run up to 200 linear ft. ¼ inch tubing should not exceed 19 ft in length. MAXIMUM FLOW CAPACITY: ½ tubing can handle a maximum of 240 GPH or 4 GPM.
Can 1 sprinkler valve control 2 zones?
Yes, it is often possible to run two valves at once. However there are several problems that can occur. You must have a sufficient water supply for both valves to run at once. If the performance of the sprinklers suffers and you start seeing dry spots in the landscape, you obviously don't have enough water.
