The pipe size for your irrigation distribution lines should be at least one to two sizes larger than the inlet of the sprinklers. For example: if the sprinkler is a Rain Bird 1800 series with an inlet 1/2" then the pipe should be 3/4" or even 1" Typical sprinkler inlets are 1/2", 3/4", 1", whereas the pipe is usually 3/4" and 1" .

Pipe size will ensure water can be supplied with ample pressure to operate each sprayhead .

A zone is referred to as a dedicated line. It has a certain amount of sprinklers that will supply a sufficient amount of water in a specific area of space.

Our complete irrigation systems are packaged according to zones, from 4 to  12.

​

Effective zoning requires map of your yard and knowledge of sprinkler spacing.

Most Rainbird sprinklers have a 25 degree trajectory upward spray, so they do not provide water coverage in their own immediate space.

It is important to space the sprinklers for head to head coverage. Meaning, if the spray distance is 12 feet, space the sprinklers every 10 or 11 feet to ensure unified coverage.
