to be placed in protective enclosure to prevent an
accumulation of substances that could prevent their proper
operation and they must have a grade level access

labor and cost will determine the best installation method.
During installation cover all open pipe ends including drip
lines to avoid getting dirt or debris into the system. Leave
enough length at the beginning and end of each drip line
for connections. It may be more convenient to finish the last
foot or so of the trench by hand. This gives more room for
connections. Beware of bending the drip tubing too tight
during installation. Do not bend tubing at the 24" radius loops
or the pipe may kink, reducing the flow. Use 1/2" flexible PVC
pipe and fittings to loop emitter pipe. The drip line will
elongate at high temperatures, do not store in direct sunlight.
To prevent stress due to contraction always leave tube snaked
from side to side of trench (1' per 100') or when plowing
