Irrigation & Sprinklers Glossary for Erie Homeowners

A device required by Erie code that prevents irrigation water from flowing backward into the drinking water supply. Must be tested annually.

The electronic brain of the irrigation system that opens and closes valves on a programmed schedule. Smart controllers adjust for weather automatically.

A low-pressure system that delivers water directly to plant roots through emitters. Uses 20-50% less water than sprinklers. Ideal for gardens and foundation plantings.

The flow rate of water available to the irrigation system. Determines how many heads can operate simultaneously per zone. Erie's water pressure affects GPM.

A sprinkler head that rises above ground when pressurized and retracts when off. Available in 4-inch and 6-inch pop-up heights.

A device that detects rainfall and suspends irrigation to conserve water. Required on new systems in many jurisdictions. Prevents watering during and after rain.

A sprinkler head that rotates to cover a large area (20-50+ feet). Driven by water pressure or gear mechanism. Used for lawns and large landscape areas.

The device that distributes water. Pop-up heads rise when pressurized. Rotary heads cover larger areas. Fixed-spray heads cover small, defined areas.

An irrigation controller that uses weather data, soil moisture sensors, or evapotranspiration rates to automatically adjust watering. Reduces water waste by 20-40%.

An underground enclosure that provides access to irrigation valves for maintenance and repair. Should be kept clear of soil and debris.

Using compressed air to purge all water from irrigation pipes, valves, and heads before Erie's first freeze. Prevents cracked pipes and damaged equipment.

A section of an irrigation system controlled by a single valve. Different zones allow watering schedules tailored to sun exposure, soil type, and plant needs.
