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.
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.
The Low Pressure Wobble Sprinkler can be joined up with other sprinklers of the same type. You will need to add extra hoses and connectors. Each of these sprinklers has an outlet opposite the water inlet which can be unscrewed to add extra sprinklers.
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.
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.
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.
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.
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”).
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.
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.
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.
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.
The most common reason that sprinklers failed to operate was the system being shut off at some point before the fire. One sprinkler is usually enough to control a fire. In 77 percent of the structure fires where sprinklers operated, only one operated. In 97 percent, five or fewer operated.
5.3.
For good uniformity several sprinklers must be operated close together so that their patterns overlap (Figure 58). For good uniformity the overlap should be at least 65% of the wetted diameter. This determines the maximum spacing between sprinklers.
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.
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.
You should run your sprinkler system for as long as it takes to apply a half inch of water to your lawn. You will need to water for at least 10 minutes per week for most systems. Measure your sprinkler system's output to ensure you're not using too much water or underwatering.
Avoid watering grass on a hot afternoon when it's 95 degrees or higher. The best time to water grass is at dawn or in the early evening. Water deeply three times a week instead of a little water daily. Test whether your sprinkler system is watering your lawn evenly.
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 in the morning (before 10 a.m.) is the best time for your lawn; it's cooler and winds tend to be calmer so water can soak into the soil and be absorbed by the grass roots before it can evaporate.
