b. On a weekly basis, make inspections on the entire system for proper
operation and coverage. Flush and adjust all sprinkler heads, valves, and all
other equipment to ascertain that they function according to the
manufacturer's data. Adjust all sprinkler heads to not overspray onto walks,
roadways, buildings, and other hardscape elements when under maximum
operating pressure and during times of normal prevailing winds. Make
appropriate pressure corrections on systems with fogging nozzles.
3. Pest Management:
