Lawn sprinkler systems: a homeowner's guide
An in-ground sprinkler system waters your lawn and beds automatically on a schedule, using buried lines, valves grouped into zones, and a controller.
The main parts
Every system has the same building blocks:
- A connection to your water supply with a backflow preventer
- Valves that switch each zone on and off
- Buried lines and pop-up spray or rotor heads
- Drip lines for garden beds
- A controller (often Wi-Fi) that runs the schedule
How zones are planned
Sun, shade, slopes and lawn versus beds each need different watering. Grouping similar areas into zones avoids overwatering one area to keep another green.
Yearly upkeep
A spring startup and a fall winterization keep the system working. Annual maintenance plans cover both.
