Their widespread adoption is due to a combination of efficiency, convenience, and aesthetic appeal.
How In-Ground Sprinkler Systems Work
The core principle behind in-ground systems is relatively straightforward. A controller, often electronic, manages the watering schedule and activates valves connected to the main water supply. When a valve opens, water flows through the underground pipes to the designated sprinkler heads within that zone. These heads then deliver water in a pre-determined pattern, covering the lawn or garden area.
These systems rely on pressure to function effectively. The water pressure in your home or business’s water supply is what propels the water through the pipes and out the sprinkler heads. It is critical to ensure adequate water pressure for the sprinkler heads to perform as intended.
The system typically includes components such as:
- A controller to automate the watering schedule.
- Valves to control the flow of water to different zones.
- Pipes, usually made of PVC or polyethylene, to transport water underground.
- Sprinkler heads, which deliver water to the landscape.
- A backflow preventer to protect the water supply from contamination.
The design and layout of the system are crucial for efficient watering. Proper planning ensures that all areas receive adequate coverage without overwatering or creating dry spots.
