Example:
• 5 feet x 12 inches = 60 inches
• 60 inches - 8 inches (2 edges x 4” setback) = 52”
• Following recommended Techline CV Row Spacing
for this example, assume 18 inches from Table 1
• 52” ÷ 18” = 2.89 spaces between Techline CV rows
• 2.89 is not a whole number, so round up to the next
whole number, which is 3 (spaces)
• Add 1 (one) to the number of spaces to determine
the number of Techline CV rows
• Determine equal spacing between Techline CV rows. 52 inches ÷ 3 = 17.3 inches
BASIC “GRID” LAYOUT:
• Headers should be indented 2” - 4” from hardscapes and planting areas.
• Headers may be PVC, polyethylene or in zones under 5-GPM, Techline CV or Techline CV Blank
Tubing.
• Headers must be sized to accommodate the flow of the zone without exceeding 5 feet per second
velocity. (Zone Water Requirement calculations are on page 10).
• Start rows of Techline CV 2” - 4” away from the edge of hardscapes, and move across the area with
equal row spacing that does not exceed the recommendations of Table 1.
(The 2” setback will help
provide enough moisture to prevent heat damage to plant material generated by hardscapes such as
asphalt). Start rows about 4” away from planting beds.
BASIC “LITE” LAYOUT:
• Water being supplied to the zone is split with a Techline fitting into two directions.
Use a TL075FTEE or TL2W075MA fitting.
• Weave the Techline CV back and forth throughout the planting area with evenly spaced rows.
• Indent the tubing 2” - 4” from hardscapes and planting areas.
• Because water is being split into two separate paths that meet in the middle, the maximum length of the
lateral can be twice the stated limit in Table 2.
• Therefore, to determine the maximum amount of Techline CV you can use in the zone, simply double
the maximum length stated in Table 2.
