What is a key characteristic of fixed spray sprinklers?

1. They are easily adjustable

2. They lack rotating parts

3. They have a very high pressure

4. They can cover large areas

The correct answer is: They lack rotating parts

A key characteristic of fixed spray sprinklers is that they lack rotating parts. This design feature allows these sprinklers to provide a consistent and uniform distribution of water over a specific area. Fixed spray sprinklers operate by emitting a fan-shaped pattern of water, which is ideal for small to medium-sized landscapes and gardens. The absence of rotating components means that fixed spray sprinklers can be less prone to mechanical failure and can operate effectively with a simple and low-maintenance structure. Additionally, because they do not rotate, their spray patterns can be precisely controlled, making them suitable for areas where targeted watering is necessary. While easily adjustable nozzles can be part of the design, this is not a defining characteristic of the fixed spray function itself. Fixed spray sprinklers typically operate at lower pressures compared to certain other types of sprinklers, allowing for efficient watering without the high pressure or water wastage. They also have limited coverage compared to other sprinkler types that are designed to cover larger areas, such as rotary nozzles or impact sprinklers.
