How far apart should rotor sprinkler heads be?
The absolute number one rule in spacing is called “Head-to-Head coverage” or Head-to-Head spacing. Head-to-Head coverage applies to both sprays and rotors. In a nutshell, it means that the heads are spaced so that they overlap from head to head. Each head should throw water far enough so that it hits the next head.
How far apart do you space sprinklers?
Sprinkler Head Spacing
| OCCUPANCY HAZARD | SQUARE FOOT PER HEAD | MAXIMUM SPACING BETWEEN SPRINKLERS |
|---|---|---|
| Light Hazard (Office, Educational, Religious, Institutional, Hospitals, Restaurants, Clubs, Theaters, etc.) | 130-200 SF per head (based on obstructions and flow calcs) | 15 ft |
How do you space a pop up sprinkler?
Sprinkler heads should always be placed so that the sprays overlap—the distance one head throws should reach the head of the next sprinkler. This is called head-to-head coverage, and sprinklers should be placed equidistantly in each zone to achieve it.
What distance is required between objects and the sprinkler heads?
18 inches away
In a nutshell, NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems says that objects that can block a sprinkler’s spray must be at least 18 inches away from the deflector.
What is the maximum number of sprinkler heads per 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 many pop up sprinklers per zone?
If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
Should sprinklers overlap?
Spray heads and rotors each have different requirements for zoning and spacing. Efficient spacing begins with an under- standing of sprinkler water distribution. Sprinklers are designed for overlapping coverage. Proper overlap ensures even distribution of water and eliminates dry spots.
How close can sprinkler heads be?
15 ft.
5.2. 1 of NFPA 13, which states that the distance from the sprinkler to the wall can be no more than one-half the allowable distance between sprinklers. The max distance between standard spray sprinklers in light hazard settings is 15 ft. (4.6 m) (with exceptions for light-hazard, combustible concealed spaces).
How many MP rotators can you put on a zone?
The standard MP Rotators have a matched precipitation rate of approximately 0.4 in/hr. This means any standard MP Rotator at any arc or radius can be placed on the same zone….Customer Type:
| Body Color | Black | Grey |
| Radius (ft.) | 8-35 | 6-16 |
| Warranty | 3 Years | 3 Years |
| FEATURES | ||
| Arc | 45-360 | 90-360 |
How many rotary 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.
Can you connect sprinklers in series?
If all your sprinklers flow rates are 1GPM you can add 3 of them on the same line to run simultaneously. If you need more sprinklers you can set them up on a separate hose and run them at a different time, essentially creating sprinkler zones.
How do you space an MP Rotator?
- MP Rotator Nozzles line at 0.4 in/hr go a distance of 8 to 35 feet.
- MP Rotator SR nozzle line at 0.8 in/hr go a distance of 6 to 12 feet.
- MP Rotator Strip models.
- MP Rotator Corner.
How much psi do MP rotators need?
④ Pressure Optimal performance and uniformity are reached at 40 PSI operating pressure. Use the Pro-Spray PRS40 to achieve pressure regulation of 40 PSI. To reach the minimum radius, use the Pro-Spray PRS30 for pressure regulation to 30 PSI. To achieve maximum radius, increase the pressure over 40 PSI.
How many sprinkler heads should be on a zone?
Sprinkler Layout Calculator Their 5000 Series Rotor with a 3.0 nozzle uses 3.11 gallons of water per minute (GPM) at 35 pounds per square inch (PSI). For example, a home with a water capacity of 10 GPM might need three heads per zone.
How many sprinkler heads should be on one zone?
What is the maximum spacing between sprinkler rotors?
If the gallonage of the rotor is less than 6 GPM the maximum spacing should never be more than 35′ between rotor type sprinklers. Stryker’s Rule: the spacing in feet between rotors can never exceed the operating pressure in PSI at the sprinkler inlet (So a rotor with a 30 PSI operating pressure = 30 foot maximum spacing between rotors.
How do you find the distance between sprinklers?
In an equilateral triangular spacing pattern, the distance “L” (the height of the triangle) is the sprinkler spacing “S” x.866. If large rotors on a golf course were spaced at 80 ft (25 m) in an equilateral triangular pattern, the distance between rows of sprinklers would be 80 ft (25 m) x.866 = 69.28 ft (21,65 m).
What are the different sprinkler spacing patterns?
The two types of sprinkler spacing patterns most commonly used are square spacing and triangular spacing. A rectangular pattern may also be used in some instances.
When should the spacing of sprinklers be reduced?
And, on projects with higher winds, the spacing should be reduced as indicated below. The triangular pattern is generally used where the area to be irrigated has irregular boundaries or borders that are open to over spray, or do not require part-circle sprinklers.
