STEPS
(continued)
• To reduce the number of glue joints, saddles or insert fittings in a header, transition to Techline CV
and Techline fittings to make up subheaders.
• Make sure to follow the guideline of not exceeding 5 GPM in the “sub-header” zone.
OTHER GRID LAYOUT CONSIDERATIONS:
• When branching out or joining rows of Techline CV, one of two rules apply:
Rule #1: When branching out Techline CV from the supply header, add up all “branched out”
dripperline and check it against the maximum lateral length listed in Table 2.
Rule #2: When joining laterals from the supply header, check only the longest lateral against the
maximum allowable in Table 2.
