How many sprinkler heads can I run off one zone?

Typically, though, a sprinkler system zone will boast 5 to 6 rotor heads and/or 8 to 10 spray heads.

How do I calculate the number of sprinkler heads per 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.

What is the 18 inch rule for sprinkler heads?

Nothing should be in that area between the bottom of the sprinkler heads and the imaginary horizontal plane parallel to the ceiling that is 18 inches below. This is done to allow an even and unobstructed spray pattern from the sprinklers when triggered to extinguish the fire.

How many Rainbird sprinklers per zone?

If your home's water capacity is 6 GPM, you could place 2 heads per zone. Consult the Performance Charts at rainbird.com or on the sprinkler label for your head's exact performance data.

Can you run all sprinkler zones at once?

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.

How many sprinkler heads per zone do you need?

Can I add another sprinkler head to existing zone?

Adding sprinkler heads is quite simple in most cases, as long as the zone you are adding to has enough supply to support the sprinkler head you want to add. In this case, I already had a good idea where the end of this line was capped, and it was very close to where another head needed to be installed.

What is the maximum distance between two sprinkler heads?

(32) In no case shall the distance between sprinklers exceed 12 ft (3.7 m).

Can sprinkler heads be too close together?

Current fire safety codes require sprinkler heads always to be a minimum of 6 feet apart from one another to avoid cold soldering.

What is the maximum ceiling height for sprinkler?

The maximum ceiling height shall be 40 ft. The minimum operating pressure shall be either 30 psi or 60 psi based upon the applicable storage and ceiling height for the installation as follows: 30 psi for storage heights up to 25 ft.

What is the maximum number of sprinkler per branch?

3.3, branch lines shall not exceed eight sprinklers on either side of a cross main.

How long do I run my sprinklers to get 1 inch of water?

On average, it will take 30 minutes to get a half inch of water. So, 20 minutes, three times per week will give a lawn about an inch of water. This formula works best with healthy, well-cultivated soil.

Can I daisy chain sprinkler heads?

Because of the multiple hose connectors, you can “daisy chain” several sprinklers together, connecting them with multiple garden hoses. This lets you water a much greater area all at once (although you need several garden hoses – see our article on Best Garden Hoses to find the best ones).

Can you run two sprinkler valves one zone?

And while it's possible to do this, the risk of creating future problems or eventually damaging your irrigation system is high. Before you even think about running multiple irrigation valves, you need to make sure that you have a sufficient water supply for both valves to run at once.

What is the minimum distance between sprinklers?

10.2. 5.4 Minimum Distances Between Sprinklers

5.4. 3 are met, sprinklers shall be spaced not less than 6 ft (1.8 m) on center. Sprinklers shall be permitted to be placed less than 6 ft (1.8 m) on center where the following conditions are satisfied: Baffles shall be arranged to protect the actuating elements.

Will touching a sprinkler head set it off?

Do fire sprinklers go off if you hit or touch them? To trigger a fire sprinkler you would have to hit the bulb itself within the sprinkler head. This is virtually impossible to do accidentally.

How Far Should sprinklers be spaced?

Meaning that spray heads should never be placed further than 15 ft. apart as this would create dry spots (i.e. dead grass) in your lawn. It is always important to install sprinklers with overlap for full coverage.

How many sprinkler heads per branch line?

Branch lines should not exceed eight sprinkler heads on either side of a cross main.

What is the standard sprinkler radius?

When properly installed, most sprinkler heads will have an 8' coverage radius. This is one of many determining factors in how the sprinkler heads must be spaced.

Should sprinkler heads overlap?

To achieve a uniform application of water over the irrigated area, the sprinklers must be spaced properly. When operated at the proper pressure, most sprinklers apply more water in the center of the pattern than at the edges. Therefore, they must be overlapped in order to give a uniform distribution.

Does each sprinkler zone have its own valve?

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.

How do I increase water pressure in multiple sprinklers?

Hook up a sprinkler booster pump for your hose.

All you do is hook your hose up to the pump, and then hook another hose up that runs from the pump to the sprinkler. Plug the pump in and turn the water on. The pump will artificially force water out of your weak water line at a much higher psi.

Can you have sprinklers and drip on the same line?

In this situation, where you have sprinkler heads and drip irrigation, the two are not compatible to run on the same zone. Drip irrigation emits water slowly (think a dripping faucet), which will require a longer water run time in order for plants to get enough water.
