What does the term “leaning test” refer to in sprinkler maintenance?

The term “leaning test” in sprinkler maintenance specifically refers to the process of aligning sprinkler heads properly. Proper alignment is crucial for ensuring that water is distributed evenly and efficiently across the intended areas. If sprinkler heads are misaligned or leaning, it can result in uneven coverage, leading to dry spots or over-saturation in certain areas, which can affect the health of the landscape being irrigated. This alignment process involves checking that each sprinkler is perpendicular to the ground and directed at the correct angle to achieve optimal performance.

Water pressure testing, temperature measurement, and leak inspection, while important aspects of sprinkler system maintenance, do not pertain to the concept of the leaning test. Each of those processes addresses different operational parameters of the sprinkler system rather than the alignment of the sprinkler heads themselves.
