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.
How far apart should I put my sprinkler heads?
The distance between the sprinkler heads should not be more than 1 foot greater than the width of the planter. In other words, if the planter is 8 feet wide you would install half circle heads on both sides of the planter, not more than 9 feet apart from each other.
How do I calculate the number of sprinkler heads per zone?
Calculating Zones Each zone should include plants with the same watering needs, or an area of the lawn. Then, add up the necessary flow rate in GPM of all the sprinkler heads, divided by the GPM of your water supply. The resulting number will equal how many zones you need.
How do I calculate sprinkler coverage?
The number one rule is to overlap the spray from sprinkler head to sprinkler head, known as “head to head coverage.” This applies to fixed spray sprinklers and rotors. “The actual distance between sprinkler heads is determined by the gpm nozzle and the water pressure in the system,” says a spokesperson of Rain Bird.
Where should sprinkler valves be placed?
Mark the location where the valves are to be buried. Position them in inconspicuous areas, such as shrub beds, if possible, with the first valve being near the main water connection. Place remaining valves according to the specific areas of the property each zone will irrigate.
How many zones do I need for my sprinkler system?
Draw Your Sprinkler Zone Plan With simple math, you can determine how many heads in each zone and then take the total number of sprinklers you need, and divide that by your head/zone number and that will tell you how many zones you need.
How many square feet does a sprinkler head cover?
New fire codes allow a single sprinkler head to protect up to 200 square feet, depending on the design of the fire sprinkler, flammability of the building and the materials within it. The NFPA delineates spacing requirements based on the material hazards, plumbing, and piping systems of the specific construction.
How many sprinklers can I run at once?
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 do you set up a sprinkler zone?
Sprinkler System Installation in 10 Steps Step 1: In-Ground Sprinkler Overview. Step 2: Dig the Trenches. Step 3: Make the Water Connection. Step 4: Install the Zone Valves. Step 5: Place the Pipes in the Trenches. Step 6: Connect the Pipe at the Valve Box. Step 7: Install the Pop-Up Sprinklers. Step 8: Roll Out the Irrigation.
What is the coverage area of a sprinkler?
Sprinkler Head Distance and Spacing Requirements Hazard Level Coverage (in sq ft) per Sprinkler Head Maximum Allowed Distance Between Sprinkler Heads Ordinary Hazard 1 & 2 (areas with moderate concentrations of flammable materials) 130 sq ft per head 15 ft.
How do you calculate gallons per minute for sprinklers?
The flow rate in gallons per minute (GPM) is: 300 (which is 5 gallons X 60 seconds in a minute) divided by the number of seconds it takes to fill the container.
How far will a Rainbird 5000 spray?
Rain Bird 5000 Series Rotors are ideal for medium to large-size lawns and evenly distribute water from 25 to 50 feet. 5000 Series Rotors with Rain Curtain Technology are engineered to deliver a uniform spray pattern, giving you superior distribution uniformity and a consistently greener lawn with less water.
Should sprinkler valves be above ground?
The normal rule is at least 6 inches above the top of the highest sprinkler head, some brands say it must be 12 inches. The anti-siphon valve will also spill water from the air vent if not installed higher than all the sprinklers or emitters. The anti-siphon valve must also be above ground.
Do sprinkler valves need to be underground?
When it comes to housing the valves, manifolds, wiring etc., you can choose to put them uncovered in a hole in the ground or use an underground valve box, unless you are installing anti-siphon valves. These have to be installed above ground. “It’s safer and better to have your manifolds and valves below ground.”Oct 1, 2007.
Should sprinkler 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 zones can a sprinkler valve control?
They can be 2-7 zone configurations. All irrigation zones get glued to it and and one pipe is the water source.
Can you combine sprinkler zones?
A. 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.
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.
Can you have multiple sprinklers on one hose?
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.
