Many residential sprinkler irrigation systems are installed with improper spacing or low pressure, which can cause coverage problems. On this recent job, we solved our customer’s problems by properly respacing the sprinkler heads to eliminate brown patches in the lawn.
This irrigation system was suffering from low pressure in the turf zone between the sidewalk and the curb, thus resulting in poor coverage and brown patches. Originally, 13 sprayers were lined up along one side of the sidewalk, which were incorrectly spaced with incorrect nozzles installed. The problem led to poor operating pressure, uneven distribution, and excessive overspray onto the street. These heads were all respaced, leaving only 11 along the sidewalk. We then installed an additional 11 along the curb to provide opposing coverage.
The existing zone was suffering from poor operating pressure, and we almost doubled the number of heads in the watering zone. Coverage and operating pressure improved with Hunter MP Rotator Nozzles. Using much less water than a regular spray nozzle, they have a much lower precipitation rate, applying water more slowly. Since they use less water per minute, we can install more heads per zone.
By respacing the heads to 15 ft and providing opposing heads along the curb, this zone now has perfect head-to-head coverage. Now, any single sprinkler head can hit as many adjacent heads as possible to provide even water distribution. The overspray onto the street and sidewalk is now cut to a minimum, so water use is now at its most efficient.
