We inspect the back flow preventer and manifolds upon arrival. Close any drains and vents before pressurizing the system. Inspect the main valve and drain then pressurize the system listening for abnormal sounds or unusual fill times. Listen for bleeding after pressurization. Reinspect the back flow preventer and manifolds for obvious leaks. Run each station and check flow and visual pressure based on station configuration. Determine if any heads are weak from possible restrictions. Adjust heads as needed for basic coverage. Program run times for each station based on head type, sun/shade exposure. and slope of grade. Program cycle days and start times. Advise customer of issues found and ask for feedback on timing and trouble areas they have experienced in the past.
