TYPES OF LAYOUTS:

There are two common layout methods that we recommend – "GRID" and "LITE". Both
accomplish the same goal, but one method will be preferred method on what you are irrigating.
"GRID" Layout:

This is the preferred method for installing Techline AS™ sub-surface.

This method uses supply and collecting manifolds with rows of Techline AS™
connected at each end.

The Supply Manifold delivers water to each row of Techline AS™.

The Exhaust Manifold forms a continuous loop, or return leg, so all rows of Techline
AS™ 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 breaks in
the laterals and allows for much easier repairs of any line breaks. It will also allow for a
flushing point to be installed on the Collecting manifold.
"LITE" Layout:

The "LITE" layout is used exclusively on-surface (under mulch installations).

It is the fastest and possibly the easiest method because no supply and collecting
manifolds are used.

The dripperline simply weaves back and forth throughout the zone at evenly spaced
rows.

WHAT DO THESE LAYOUTS HAVE IN COMMON?


Both methods assume even row spacing will be maintained.

Both methods are designed to flow water in a loop manner.
