An irrigation system is typically divided into several zones, each of which feeds sprinkler heads in a different area of the lawn or garden, and each zone is controlled by a valve that receives signals from a centrally located controller. … Often the valves are located inside one or more in-ground valve boxes.
How do sprinkler zones work?
Each area, with unique watering needs, gets broken into zones. The zones will be set up with different sprinkler heads and watering systems to make sure water covers the area. Your bushes and shrubs will need less water than grassy areas. The irrigation specialist will consider whether the zone is in the sun or shade.
How do I know if my sprinkler system has a master valve?
It is connected to the “master” or “pump” connection in your controller. For Generation 1 controllers, this is the blue terminal in the wall mount. For Generation 2 controllers, find the terminal marked “M”. In the image below, the master valve is in the small circular box to the left of the main sprinkler box.
Why would a sprinkler zone not work?
Each zone consists of several sprinkler heads controlled by a valve that is electrically activated. If a single zone is not working, the problem is usually an electrical issue or a defective controller or solenoid.How many heads are in a zone?
At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
How do I know if my sprinkler solenoid is bad?
- The Water Won’t Shut Off. If you have this problem, it’s very likely the solenoid. …
- Low or Uneven Water Pressure. The solenoid controls the water pressure. …
- Water Leaks. There are many points in a sprinkler system that can leak. …
- Current Testing. …
- Valve Inspection. …
- Parts Replacement.
Can you run two sprinkler valves one zone?
Yes, it is often possible to run two valves at once. … You may need to do some adjusting of the sprinklers as the water pressure operating them is likely to be less when two valves are on. Both valves running at the same time may require more water than the pipe supplying them can reasonably handle.
Should solenoid be on or off?
Avoid over-turning the solenoid in either direction, as this can cause damage to the components or cause pressurised water to escape the solenoid. When you hear water rush through the device, it’s easy to tell that the valve has opened successfully.Why does one of my sprinkler zones have no pressure?
Often when your sprinkler system was running fine, and then one zone began to lose water pressure, the culprit is a leak in the zone’s lines or a leak at a nozzle or two. Leaking nozzles won’t produce the same water pressure and need to be replaced, which is fairly simple.
How do you test a valve solenoid?- Set your multimeter on ohms. If the multimeter is not automatic, set it on 2k ohms. …
- Place the probes of multimeter across the pins of a solenoid coil. If you find 3 pins there, one of them is a flat pin which is connected to the ground. …
- Read the number on the multimeter.
Do you need a master valve for sprinkler system?
If your mainline is located in a place where a leak might cause severe property damage or a danger to the public, you should use a master valve. If you are willing to pay the price of a flow monitoring irrigation controller with a flow sensor, a master valve can be used as a water conservation measure.
Do I need 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.
Do I need a master solenoid?
Having a Master Solenoid is essential for any reticulation system for a number of reasons. … A reticulation system without a Master Valve is always under pressure; what this means is the main supply pipe, which is usually PVC piping, is under pressure the whole way to each solenoid.
Can I run all sprinkler zones at the same time?
Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.
Why are multiple sprinkler zones coming on at the same time?
Water is coming out of multiple zones at the same time: For the valves to stay open in one zone, while shutting outlets in other zones, there needs to be a minimum amount of water pushed through the valve. … To investigate further causes and solutions, go to our FAQ page and look under “Indexing Valves.”

How many sprinklers can I run on one line?
For example, you generally have a flow rate of 10 gpm from a ¾-inch spigot where you connect your hose. With your 10 gpm flow rate at your spigot, you could run two sprinklers at 5 gpm each. The best set-up is to run two hoses from the spigot–each to one sprinkler.
How does an irrigation doubler work?
DOUBLER will allow you to operate two sprinkler valves independently on one set of field wires . Add a new valve without trenching in new wire by connecting the new valve AND the nearest operating valve to the DOUBLER. The DOUBLER will operate both valves separately on one hot wire and the common.
