An automatic timer is used to turn your sprinkler system on and off. The timer tells your valves which days to water, when to turn on, how long to water and when to shut-off. Single station mechanical timers generally control your system on off, days to water, and watering duration through the use of tripper pins. Multi-station programmable timers are basically computers which allow specific watering cycles, duration and times depending on the needs of your yard. |
