CIT Irrigation System Installation & Maintenance 2

Question 1

When scheduling irrigation for a newly installed turf lawn (sod or seed), the watering frequency should initially be:

Accepted Answer

Multiple times per day with short run times to keep the surface consistently moist until roots establish

Answer

New turf — whether sod or seed — requires frequent, light watering (2-4 times daily for seed, 1-2 times daily for sod) to keep the surface and root zone consistently moist. Deep, infrequent watering is appropriate only after roots have established (typically 3-6 weeks).

Question 2

During a routine maintenance visit, a technician notices that several spray heads on a zone are producing a fine mist rather than a defined spray pattern. This indicates:

Accepted Answer

Operating pressure at the heads is too high, causing misting that wastes water through wind drift and evaporation

Answer

Misting from spray heads indicates excessive pressure, which breaks the water stream into tiny droplets susceptible to wind drift and evaporation. Spray heads typically need 30 PSI — pressures above 40 PSI cause significant misting. Pressure regulation is the solution.

Question 3

A proper irrigation system maintenance checklist should include all of the following EXCEPT:

Accepted Answer

Adding chlorine to the mainline to improve water quality

Answer

While sprinkler inspection, leak repair, and controller/sensor testing are standard maintenance items, adding chlorine to the mainline is not a routine maintenance procedure. Chlorine treatment is only used in specific situations like treating drip system biological clogging under professional supervision.

Question 4

After completing an irrigation repair, the technician should always:

Accepted Answer

Test the repaired zone, verify proper operation, document the work performed, and inform the property owner of any remaining issues

Answer

Professional service requires testing all repairs before leaving the site, documenting the work performed (including parts used and any warranty information), and communicating any additional issues discovered during the repair to the property owner.

Question 5

An irrigation system installed with reclaimed (recycled) water must have what distinguishing feature on all above-ground components?

Accepted Answer

Purple identification — purple pipe, purple valve box lids, purple tags on heads, and warning signs stating 'RECLAIMED WATER - DO NOT DRINK'

Answer

All reclaimed water irrigation components must be clearly identified with purple coloring (Pantone 522C) and warning signage. This includes purple pipe, purple valve box lids, purple caps on heads, and signs at the controller, meter, and visible valve boxes.
