AprilAire® ZAZW Water Sensor Protect your home from hidden leaks and water damage with instant alerts. The AprilAire® ZAZW Water Sensor is a compact, easy-to-install sensor designed for basements, crawl spaces, and other hard-to-reach areas where water damage often begins. Pair it with an AprilAire® Wi-Fi Dehumidifier or S86WMUPR Thermostat to receive instant alerts straight to your phone through the AprilAire® Healthy Air App. With flexible mounting options and a slim profile, this sensor can be placed horizontally for surface leak detection or vertically with the included bracket for tight spaces. Its 6-foot lead wires allow you to reach difficult areas like under appliances or near sump pumps. What Is This For? This sensor is designed to detect water before it becomes a major problem. It’s ideal for protecting areas of the home where leaks are most likely to start, such as: Crawlspace entries and foundation walls Sump pumps and condensate pumps Water heaters and appliances (washers, dishwashers, refrigerators) Drainage lines, hose connections, sinks, and toilets Areas prone to sewage backups or leaks By pairing with the AprilAire Healthy Air App, homeowners get instant water alerts, low-battery notifications, and historical data to stay ahead of potential damage. Requirements Wi-Fi Enabled AprilAire Device: Must be paired with either an AprilAire S86WMUPR Thermostat or an AprilAire Wi-Fi Dehumidifier for monitoring and alerts. App: Requires the AprilAire Healthy Air App (iOS or Android). Power: CR2 lithium battery (included, up to 3.5-year life). Wireless Range: Up to 100 ft from paired device (Zigbee 2.4 GHz). If you own a non-Wi-Fi Aprilaire model (E070, E080CS, E100, E100V, or E130), the sensor will not connect directly. To enable app alerts, you’ll need to pair it with an Aprilaire S86WMUPR Wi-Fi Thermostat, which acts as the hub for the sensor. Best Practices for Use: Place a sensor near the dehumidifier’s condensate pump or drain line to detect leaks early. Position additional sensors in high-risk crawl space areas: near sump pumps, water heaters, foundation walls, or under plumbing lines. For large crawl spaces, use multiple sensors (up to 9 per Wi-Fi device) to cover different zones. This setup ensures you’re alerted at the very first sign of water, keeping both your crawl space and your dehumidifier protected. Key Features Instant Alerts: Get notified on your phone if water is detected or if the battery is low. Wide Coverage: Connect up to 9 sensors per Wi-Fi enabled AprilAire device. Flexible Placement: Mount horizontally on floors or vertically with bracket for walls/pillars. Long Battery Life: Up to 3.5 years with the included CR2 lithium battery.
