Orbit 57009 Pump Start Relay for Sprinkler Controllers — 24VAC Control, 1HP/2HP Pumps, Weatherproof Outdoor Enclosure

Overview

The Orbit 57009 Pump Start Relay is a compact, weather‑resistant device designed to synchronize your irrigation pump with your sprinkler timer. By bridging a 24 VAC controller with the pump’s power circuit, it helps your watering schedule stay in sync across a range of water sources, including wells, ponds, and bore holes. The unit is built to withstand outdoor conditions, with a durable enclosure that protects its electronics while you manage seasonal irrigation needs.

With this relay, you’re not just turning a pump on or off—you’re coordinating a larger watering routine. The system operates behind the scenes, letting your sprinkler controller trigger the pump at the right moments so irrigation runs smoothly without manual start-ups or constant monitoring. It’s compatible with 24 VAC irrigation controllers from Orbit, Hydro-Rain, and other major brands, making integration with existing systems straightforward.

Key capabilities

• Automatic synchronization between an irrigation pump and sprinkler controller
• Rugged ABS enclosure that resists weather, sun, and moisture for long-lasting outdoor use
• Pump control for 120 VAC up to 1 HP and 230 VAC up to 2 HP, covering typical home and small commercial setups
• Compatibility with 24 VAC irrigation controllers from Orbit, Hydro-Rain, and other major brands

Real-world uses

Well, pond, or borehole water sources are common scenarios where this relay shines. When the controller signals watering, the relay energizes the pump so water flows in sync with the timer—reducing manual intervention and helping you maintain a steady irrigation rhythm.

Outdoor installations benefit from the weatherproof housing, which protects the electronics in rain, dust, or sun. The 24 VAC control input keeps wiring practical and consistent with typical sprinkler systems, simplifying setup and future upgrades.

Why it matters

For households and small properties, the Orbit 57009 offers a versatile way to coordinate pump operation with existing controllers. Benefits include streamlined watering cycles, compatibility with popular controller brands, and the flexibility to support a range of pumps. While results depend on your specific configuration, the relay enables a cleaner, more integrated irrigation workflow without promising outcomes.
