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.
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.
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. Suggested sprinklers for this set-up are the Residential Sled Base Sprinklers or the Tripod Sprinklers.
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.
Branch lines should not exceed eight sprinkler heads on either side of a cross main. Areas within fire walls may be subdivided into separate fire areas by one-hour partitions.
Light Hazard (10-15 ft). Excluding heads in combustible concealed spaces, all sprinklers in this category have 15 feet (4.6 meters) of maximum allowable spacing between them. Ordinary Hazard (15 ft). All sprinklers in these environments have a 15-foot (4.6-meter) maximum.
Current fire safety codes require sprinkler heads always to be a minimum of 6 feet apart from one another to avoid cold soldering.
With the system shown here, the local code requires that the anti-siphon sprinkler valve must be at least 6 inches above the highest sprinkler head in the same zone when the head is in the popped-up position. Check with your local building department for specific height requirements that apply to your project.
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.
As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want. We support up to two solenoids per zone output, plus a master valve, for a total of three solenoids at any given time.
Every brand of sprinkler is different, but there's typically a pressure valve on the top that you can turn manually to increase the pressure. There's also a deflection guard on the side of the head you can adjust to change the breadth of the water.
Not more than 1000 automatic sprinklers shall be controlled by any one preaction valve.
Different types of irrigation equipment have different ideal operating pressures for maximum efficiency. For rotors, this is about 45 psi, with an operating range of 25 to 65 psi. For spray heads, it is 30 psi, with an operating range of 15 to 30 psi.
Nothing should be in that area between the bottom of the sprinkler heads and the imaginary horizontal plane parallel to the ceiling that is 18 inches below. This is done to allow an even and unobstructed spray pattern from the sprinklers when triggered to extinguish the fire.
1.3 lays out the “Three Times Rule” which states that unless specific requirements are met that “sprinklers shall be positioned away from obstructions a minimum distance of three times the maximum dimensions of the obstruction”, up to a maximum of 24 inches (0.6096 m) though the “maximum clear distance does not apply ...
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.
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.
Sprinklers shall be located a minimum of 4 in. (100 mm) from a wall.
Do not install cable trays, heating ducts or other large obstructions closer than 3 times its width, to a sprinkler head. (i.e. if the duct is 2 ft (0.6 m) wide, then it should be 6ft (1.8 m) from the sprinkler head.)
Most irrigation systems have nine zones or less. It's pretty common to have 6-9. Part of it boils down to your water source, and how much water it can pump out.
3.1, 18.4(d) and 19.1.2.3, where the maximum ceiling/roof height is 40 feet.
