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.
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.
You can operate 2 or 3 sprinklers at one time with 'Y's and extra hoses, depending on your water pressure. To run more than one sprinkler off the same faucet, attach a 'Y' to your faucet and run a hose to each sprinkler.
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.
1. Water Thoroughly: Rotor zones should run for about 30-40 minutes per zone and spray zones 10-15 minutes per zone. 2.
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.
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).
Not more than 1000 automatic sprinklers shall be controlled by any one preaction valve.
On the other hand, watering longer but less frequently, “deep watering,” produces deep roots that mean lawns can better survive periods of drought. The ideal watering schedule is once or twice per week, for about 25 to 30 minutes each time.
The “Four Times Rule” is really just an extension of the “three times rule” however it covers extended coverage sprinklers and the maximum clearance is 36 inches (0.9144 m).
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.
The ideal time to water, therefore, is early in the morning between 4 am and 8 am. Your lawn will have time to absorb the moisture deep down to promote root growth, but will not be too damp by dark that it encourages fungus and other problems. The number of hours of continuous wetness should be kept to a minimum.
5. 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.
Maximum Distance from Wall: half (1/2) of the maximum distance between sprinkler heads. Minimum Distance Between Sprinklers: typically 6'-0". Distance from Ceiling: minimum 1", maximum 12" for unobstructed construction.
The average sprinkler head shoots out water at a distance of 55 to 60 feet, shooting out approximately 15 gallons per minute. This is enough to keep a lawn well irrigated. If your soil is particularly low in pH, consider a lime application.
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.
Don't water your grass before mowing. Wet grass tends to clump together on the lawn which could suffocate the grass underneath or promote fungal growth. Also, it could clog up your mower. Mowing is an essential aspect of home maintenance.
Once sprinkler donuts have been installed, you can mow around the area safely. If you want additional precautions, you can plant small flags around your yard near each sprinkler head. These visual cues alert you when you approach a sprinkler head, allowing you to avoid it with the lawnmower.
Don't water everyday.
The more shallow your grass roots are, the less hearty it will be in hot weather. Instead water about two times per week for longer periods of time. The local lawn companies I have spoke with around my area (North Central Texas) recommend about 20-30 minutes per watering cycle twice a week.
Watering with a typical sprinkler using a standard 5/8" garden hose for one hour uses about 1,020 gallons of water; if you water three times per week, that's about 12,240 gallons per month.
If your sprinkler output is 1½ inches per week, your sprinklers should run for only ⅓ hour or 20 minutes that week (½ divided by 1½). On a twice-weekly watering schedule, run your sprinklers 10 minutes each time.
