The Brass Float Switch is a direct replacement part used in Aqua-Hot & Hydro-Hot hydronic heating systems to monitor antifreeze fluid levels in the tank. This switch sends a low-fluid signal to the controller or dash panel, helping prevent damage due to low coolant.

Important Information
  • Fluid Level Monitoring – Detects when antifreeze in the reservoir drops below a safe level and signals the system to alert the user.
  • Brass Construction – Durable, corrosion-resistant brass body for long-term reliability in heated fluid environments.
  • Critical Safety Component – Helps prevent pump burnout and heating system failure due to low fluid conditions.
  • Genuine OEM Replacement – Designed for perfect compatibility and optimal performance in Aqua-Hot & Hydro-Hot heating systems.
WARNING: CRITICAL COMPONENT – IMPROPER REPLACEMENT CAN LEAD TO SYSTEM MELTDOWN!
