  • 24/7 Dual-Action Leak Protection: Don’t let a clogged drain line turn into a thousand-dollar repair bill. This professional-grade flood sensor is your home’s final line of defense against condensate overflow. Designed to monitor primary or secondary drain pans, our water leak detector provides a dual-action response: it acts as an emergency switch to instantly shut down your HVAC system and stop water production, while simultaneously triggering an alarm to alert you before damage occurs.
  • Advanced 5-Wire Universal Integration: Our flood sensor features a premium 22AWG 5-conductor cable. This 5-lead wired configuration separates the power supply from the signal switch, ensuring these water sensors are compatible with virtually any HVAC setup—including high-efficiency furnaces, heat pumps, and water heater units. This professional level of flexibility allows you to achieve the ultimate flood protection.
  • ETL Certified: When it comes to your home's electrical system, never compromise. Our flood sensor is ETL Listed and rigorously tested to meet North American safety standards. This water leak detector is engineered to integrate safely with your HVAC control board, ensuring reliable water detection performance that won't cause electrical interference or damage your expensive equipment. It is the perfect choice for professional prevention.
  • Internal Alarm & External Connectivity: Take control of your home’s safety with our synchronized triple-action warning response. Thanks to the dedicated signaling wired lines, this leak sensor does more than just stop the water—it communicates. When wetness is detected, it instantly shuts down the HVAC unit, triggers its built-in audible alarm, and sends a signal to external alarms, light indicators, or smart home gateways like resideo.
  • No More False Alarms: Tired of the AC cutting out for no reason? Our flood sensor features an innovative elevated base. By lifting the water detection points above the very bottom of the pan, these water leak detectors avoid "nuisance alarms" caused by minor condensation ripples or common debris. You get high-precision moisture monitoring that only triggers when a real water level threat exists, making it more reliable than a standard floor switch.
  • Intelligent Multi-Zone Linkage & High-Load Reliability: Featuring a robust 5-conductor architecture and a 3-Amp high-load capacity, our sensors are engineered for professional, corporation-level system integration. This allows you to wire multiple flood sensors in series across different basements or zones while keeping individual unit controls separate. It is the ultimate fail-safe water leak solution for large properties, ensuring any wetness triggers a warning and shuts down the system.
  • Epoxy-Encapsulated for Lifetime Durability: Built to survive in harsh basement environments, the internal electronics of our water sensor are 100% encapsulated in high-grade epoxy. This creates a moisture-proof and anti-corrosion seal. Whether installed in a damp basement, a sweltering attic, or near a floor drain, these water leak sensors provide a lifetime of maintenance-free reliability.
  • Versatile Mounting for Every HVAC Setup: Whether you’re protecting a high-wall mini-split, a basement furnace, or a horizontal attic air handler, our compact flood sensor fits where others can't. Its low-profile design and non-corrosive housing make it the ideal water leak detector for secondary drain pans in any orientation. The 4.6ft lead wire provides ample length for flexible placement on the floor or inside the unit for superior wet area monitoring.
  • Instant Visual Diagnostics: Maintenance is made effortless with built-in status light indicators. A steady green LED means your water leak sensor is actively protecting your home. If a leak is detected, the light turns red. Use the integrated "One-Click" test switch to verify the alarm is ready for action, ensuring your water leak detectors are always standing guard against flood damage.
