Site location : Front lawns outside office
Specific location of irrigation system : see plan below
Problem : One of the Hunter fittings on the semi-automatic pressure system was not attached properly. Required re-fitting and a flush of that part of the system.
Tools Used : Shovel, wheelbarrow, bucket, plumber's tape.
OH&S issues : slippery paving surfaces, a small hole where the hunter fitting had previously been dug out, weather not ideal for maintenance (raining). Surrounding ground already quite wet from rain over night, limiting time able to spend on running the system (don't want to oversaturate site)
.
Hunter fitting removed and screen filter removed and washed in soapy water.
New thread tape placed around fitting, opposite to direction it screws in to riser.
Lower sprinkler heads dug up and positioned above soil ready to flush system (heads are on articulated risers). Following flushing, heads replaced with the top kept level to turf. System activated by manual over-ride at solenoid and head alignment adjusted.
Maintenance 2
Site location : propagation house
Type of irrigation system : misting system, using micro-sprinklers.
Work : Remove fittings, clean filters and flush system. Leaf sensor checked and arm balance adjusted appropriately.
Equipment used : bucket, warm soapy water, plumber's tape.
