What is the role of the nozzle in an irrigation sprinkler?
The nozzle is the interchangeable top part of the sprinkler that actually determines the watering pattern. It dictates the radius (distance) of the water jet, the coverage angle (e.g., 90°, 180°, 360°), and the precipitation rate (how much water reaches the ground).

What is the difference between fixed and adjustable nozzles?
Fixed nozzles have a predefined watering angle from the factory (such as quarter-circle, half-circle, or full circle) and offer extremely precise distribution. Adjustable nozzles allow manual adjustment of the angle (from 0° to 360°), providing maximum flexibility for irregular lawn shapes.

Can nozzles be replaced without changing the sprinkler body?
Yes, the main advantage of modern pop-up sprinklers (such as those from Hunter, Rain Bird) is that they use universal threads. You can easily unscrew an old or inefficient nozzle and install a new one, without digging or replacing the buried sprinkler body.

What are rotary nozzles (MP Rotator) and what advantages do they offer?
Rotary nozzles (MP Rotator type) are mounted on the body of spray sprinklers but emit multiple fine rotating jets. These reduce instantaneous water consumption by up to 30%, prevent runoff on sloped terrains, and significantly increase the coverage range compared to classic sprays.
