Use garden irrigation timers to automatically water gardens and plants on a set schedule or custom intervals by connecting the timer to the water system and programming it according to the device's instructions. Some models require hardwiring to a power source, while others include internal batteries or remote access functionality.
A garden irrigation timer uses an internal time monitoring system to regulate the flow of water through a water system. When the timer meets the programmed time conditions, it initiates the flow of water in the given area for the specified duration. Most timers repeat the process either at the same times each day or on custom intervals, depending on the complexity of the system. This allows you to water plants without having to physically be present to operate the waterflow.
In all cases, place the timer at a or near the main water flow into the irrigation system, so it can properly direct the water flow throughout the circuit. Once the timer is installed, follow its programming instructions to set the times at which it waters the garden, typically by entering values into an interface that includes a digital clock readout. Some devices connect to a wireless network and can be programmed through a computer or a smartphone app. These devices also frequently include options to immediately turn on or off the water flow.
