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.
This is where you need to break out your calculators! Or, if you prefer, simply leave the irrigation design up to an installation professional, so you can be guaranteed head-to-head coverage. Typically, though, a sprinkler system zone will boast 5 to 6 rotor heads and/or 8 to 10 spray heads.
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.
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.
As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.
1. Water Thoroughly: Rotor zones should run for about 30-40 minutes per zone and spray zones 10-15 minutes per zone. 2.
Sprinkler heads must be a maximum of 12-15 feet apart, depending on the hazard rating of the space (it ranges from Light Hazard to Extra Hazard 1&2), and at least half that distance from the nearest walls (typically 7.5 feet away).
5.4 (pendent and upright) and 10.3. 4.4 (sidewall), require 6 feet of clearance between heads. That minimum distance is measured from the center of each sprinkler head (or, “on center”).
One sprinkler does the job pretty well. And while my setup doesn't reach the edges of my yard, I do have the option of installing up to three additional Quick-Snap sprinklers down the road. These can either be daisy-chained together to function as one unit or used independently when needed.
A common rule that is followed for obstructions within 18 inches of the sprinkler deflector is the “three times rule”. This requires sprinklers to be positioned away from obstructions a minimum or three times the maximum dimension of the obstruction.
Daisy chain connectivity
Multiple sprinklers can be joined to increase coverage distance. Look for Flow through connection feature on the sprinklers to join multiple sprinklers.
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.
Most spray and rotator heads are designed to work their best at about 30 psi. When pressure is lower, the watering radius will be reduced, so you may need to place your heads closer together to get the coverage you need. Higher pressures – those above about 40 psi – will cause the head to mist or fog.
Never Mix. One thing you want to remember is that you don't want to mix these all on the same irrigation zone. That's because there are the different precipitation rates we talked about. Remember, the spray heads here have a precipitation rate that's two to three times more than your rotors or your rotary nozzles.
The answer, like so many great engineering answers, is “it depends.” Experience and testing have shown sprinklers to be effective and necessary at heights in excess of 50 feet. For this reason, most installations should not have a limit on the height they can be installed.
Keep the spray at least 2 feet away from the house. Change your timing. Your system doesn't need to run every day. Haslem suggests setting it to run for 30 minutes, three times per week.
The standard sprinklers that we normally use for storage applications cover 100-130 Sq. Feet with one sprinkler head. For extended area or for larger properties (in acres), the range must be increased and may become 144-196 Sq. Feet for each sprinkler head.
To run more than one sprinkler off the same faucet, attach a 'Y' to your faucet and run a hose to each sprinkler. To run 2 sprinklers off the same hose line, attach a quick-connect to one branch of the 'Y' and a hose to the other branch.
Distribution uniformity is increased by head-to-head spacing. This occurs when sprinkler heads are located a distance of 50% of the nozzle throw diameter from the adjacent head. In other words, a sprinkler head with a 10-foot throw should be spaced 10 feet from the adjacent head.
It is ideal to water lawns about one inch of water per week. To determine how long you need to water to get one inch, place a plastic container in your yard and set a timer. 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.
Water Wisely
Most lawns need to be watered no more than three days a week in the spring as well as in the summer and two days a week in the fall. This watering schedule is recommended under normal water supply conditions.
Watering every day is not advised. It should be done 2 to 3 times per week only to prevent a shallow root system. If possible, water during the early morning hours to ensure that the lawn dries entirely before nightfall. However, watering at any time of the day is better than not watering at all.
