“GRID”:
• This is the preferred method for installing Techline CV subsurface
• This method uses supply and exhaust headers with rows of Techline CV connected at each end
• The Supply Header delivers water to each row of Techline CV
• The Exhaust Header forms a continuous loop, or return leg, so all rows of Techline CV are being
supplied from both ends
• This interconnection of the piping network comprises the term “Grid layout.” This evens out the flow,
helps ensure water is being delivered downstream of any break in the laterals, and allows for much
easier repairs of any line breaks.
TYPES OF LAYOUTS:
There are two layout methods we recommend - “GRID” and “LITE”. Both accomplish the same goal, but
one method will be the preferred method based on what and how you are irrigating.
“LITE”:
• The LITE layout is used exclusively on-surface
• It is the fastest and easiest layout method because no supply and exhaust headers are used
• The dripperline simply weaves back and forth throughout the zone in evenly spaced rows.
WHAT DO THESE LAYOUTS HAVE IN COMMON?
• Both methods assume even row spacings will be maintained
• Both methods are designed to flow water in a loop manner
