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.How do you 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 many sprinkler heads do I need?
Consider the distance of each sprinkler head. If they distribute water in a circumference of 8 feet around, place them 4 feet apart to ensure every part of the lawn gets watered. Whatever the maximum spray distance of the sprinkler head, divide it in half to find out how far apart to place your sprinklers.
How many sprinklers can I run at once?
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.
How many sprinkler heads are in a head box?
At a minimum, your fire sprinkler head replacement cabinet should contain six spare fire sprinkler heads and a fire sprinkler wrench suitable to the type of sprinklers in-use. Fire code varies from city to city.
How many sprinkler heads per zone do you need?
How many valves does a sprinkler system have?
Most automatic sprinkler systems are set up with two types of valves. A brass "gate valve" or "ball valve" is usually located right after the "tee" where the sprinkler system cuts off from the main source of water to the house.
How do I increase water pressure in my sprinkler system?
Hook up a sprinkler booster pump for your hose.
All you do is hook your hose up to the pump, and then hook another hose up that runs from the pump to the sprinkler. Plug the pump in and turn the water on. The pump will artificially force water out of your weak water line at a much higher psi.
What is the best size pipe for a sprinkler system?
The pipe that extends from your home's water supply to the irrigation area is the main line. Holding the bulk of the water volume, this pipe size should range from 2 to 3 inches in diameter. You need this diameter so the water pressure is not significantly reduced before entering the garden.
How do you do multiple sprinklers?
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.

What is the minimum distance between sprinkler heads?
The minimum spacing between two sprinklers is 6 feet. The maximum distance a sprinkler can be installed from a wall is half the maximum spacing between two sprinklers. The minimum distance a sprinkler can be installed from a wall is 4 inches.
How many square feet does a sprinkler head cover?
For example for storage applications the standard sprinklers used in CMDA, ESFR, and CMSA range between 100-130 square feet of coverage per sprinkler head. In the case of the extended coverage heads the square footage can range between 144-196 square feet per sprinkler head.
How deep do sprinkler pipes need to be?
To prevent sprinkler lines from becoming tangled in grass roots, pipes must be installed at least 4 inches below ground. This depth will put the lines out of reach of grass. To make sure your lines are installed at a proper depth in grassy surfaces, use sprinkler bodies that have a total depth of 4 inches.
How long can a sprinkler line be?
Limit the use of ¼ tubing to no more than 12 inches in length per run. LENGTH OF RUN LIMITS: ½ inch tubing can run up to 200 linear ft. ¼ inch tubing should not exceed 19 ft in length.
Can I use PEX for sprinkler system?
PEX piping for irrigation systems is a good option due to cost, reliability, ease of installation, and flexibility. The benefits of PEX over other rigid pipes outweigh the negatives. Whether you plan to use it above or below grade, PEX for irrigation systems is a good idea.
Why does one of my sprinkler zones have no pressure?
Often when your sprinkler system was running fine, and then one zone began to lose water pressure, the culprit is a leak in the zone's lines or a leak at a nozzle or two. Leaking nozzles won't produce the same water pressure and need to be replaced, which is fairly simple.
Why are my sprinklers not getting enough pressure?
If the pressure is low at only one or two sprinkler heads, they may simply be dirty. Examine the sprinkler head and filter and clean if needed. Grass can also grow around the base of the sprinkler heads and cause them not to pop up fully, so trim and clear away any obstructions.
What causes sprinkler heads to not pop up all the way?
If you're noticing that your sprinkler heads aren't popping up and engaging, it's, again, a water pressure issue. Most heads require a specific minimum amount of PSI of water pressure to engage. If you have a completely busted sprinkler head and don't notice it, then your system will suffer for who knows how long.
How much does it cost to add a sprinkler head?
On average, sprinkler head replacement costs between $65 and $90 to hire a professional, or $2 to $12 per head if you replace them yourself. The cost to install additional sprinkler heads is between $94 and $103. Replacing or relocating sprinkler heads for your entire lawn will cost about $400.
Is there a valve for every sprinkler zone?
An irrigation system is typically divided into several zones, each of which feeds sprinkler heads in a different area of the lawn or garden, and each zone is controlled by a valve that receives signals from a centrally located controller.
Can 1 sprinkler valve control 2 zones?
Yes, it is often possible to run two valves at once. However there are several problems that can occur. You must have a sufficient water supply for both valves to run at once. If the performance of the sprinklers suffers and you start seeing dry spots in the landscape, you obviously don't have enough water.
How do sprinkler zones work?
Each area, with unique watering needs, gets broken into zones. The zones will be set up with different sprinkler heads and watering systems to make sure water covers the area. Your bushes and shrubs will need less water than grassy areas. The irrigation specialist will consider whether the zone is in the sun or shade.
