You need to plan and draw the layout for your main sprinkler line and lines for each zone.

Main Sprinkler Line

Draw the Main

Sprinkler Line

Route

Use a direct route

to draw the main

sprinkler line from

the main shut-off

valve to the front

and back yard

manifolds.

mportant: Your main

prinkler line should be

1 size larger than the

water main supply line.

Header and Later

al Lines Guidelines

Header lines – Attaches to a valve and supplies water to the lateral lines

• Do not use pipe smaller than 1"

• Do not attach sprinklers to this line

Lateral lines – Pipe that branches off from the header line and supply water to the sprinkler heads

• Do not use pipe smaller than 3/4"

Good Layout Example

This is a good layout because the water is evenly distributed

between the lateral lines and individual sprinklers.

Bad Layout Example

This is a bad layout because there is no header line. The

sprinkler heads, located at the end of the line, will have less

water pressure than the heads located closer to the valve.
