How to Turn Off B-hyve Sprinkler Systems for Winter

Winterizing your B-hyve sprinkler system prevents freeze damage. Start by disabling the controller, draining water from pipes, and shutting off the main water supply. Use manual drain, auto-drain, or blowout methods depending on your system. Always disconnect power and remove backflow preventer water.

Step-by-Step Winter Shutdown Guide

  1. Turn off the water supply: Locate the main shutoff valve and close it to stop water flow to the system.
  2. Disable the controller:
    • Set the controller to "Rain Delay" or "Off" mode.
    • Unplug the transformer or turn off the circuit breaker to cut power.
  3. Drain the system: Choose one method below (see comparison table).
  4. Insulate exposed components: Wrap backflow preventers, valves, and pipes with foam insulation.
  5. Remove batteries (if wireless): Prevent corrosion in battery-powered controllers.

Comparison of Winterization Methods

Method Time Required Tools Needed Best For Cost
Manual Drain 30-60 mins None (or wrench for drain valves) Small systems, DIYers $0
Auto-Drain 10-20 mins None (system must have auto-drain valves) Systems with built-in auto-drain $0
Blowout (Air Compressor) 1-2 hours Air compressor (50-80 CFM), safety gear Large systems, professional results $50-$200 (if renting equipment)

Manual Drain Method (Detailed Steps)

  1. Open all manual drain valves on the system (located at low points).
  2. Activate each zone valve one by one to release trapped water:
    • Turn the controller to "Test" mode.
    • Run each zone for 2-3 minutes to empty pipes.
  3. Open test cocks on the backflow preventer to drain residual water.
  4. Leave all valves open until spring to prevent pressure buildup.

Critical Mistakes to Avoid

  • Skipping the backflow preventer drain: Water left here can crack the device.
  • Using a weak air compressor: Blowout requires 50+ CFM-household compressors often fail.
  • Closing drain valves after winterizing: Trapped moisture can freeze and expand.
  • Ignoring the main shutoff valve: Even drained systems can refill if the valve leaks.

Reactivating Your System in Spring

  1. Close all drain valves and test cocks.
  2. Slowly turn on the main water supply (watch for leaks).li>
  3. Reconnect power to the controller and restore settings.
  4. Run a test cycle to check for damaged zones or sprinkler heads.
