    This means that the water from one sprinkler must spray all the way to the next sprinkler in all directions- to the right, left and also to the head across from it. This is very important, spacing the sprinkler heads too far apart is one of the most common design errors, and it is almost impossible to go back and correct the problem later. An in-ground lawn sprinkler system consists of several key components. In the typical system, a water supply pipe from the main water source first passes into a valve box set at ground level, where it is divided into individual underground irrigation zones, each controlled by its own zone : Aaron Stickley.

    A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by properly designed and maintained fire sprinklers, over 99%.

When you use the radius adjustment on a spray you are simply reducing the water pressure by closing a small valve in the nozzle. As the pressure drops, so does the radius. Adjust the master valve of your sprinkler system by turning the flow control clockwise until the stream of water from the nozzle begins to drop.

This lowers the water pressure. Turn the flow master valve flow control slowly until the spray pattern reaches its full radius. Fortunately, you can troubleshoot your lawn sprinkler problems easily.
