The Basement Watchdog 110 dB Water Alarm with Detachable Sensor (BWD-HWA)

Protect your space with a reliable water alarm

The Basement Watchdog 110 dB Water Alarm with Detachable Sensor (BWD-HWA) is a compact safety device designed to shield basements, laundry rooms, crawl spaces, and other moisture-prone areas. It provides an early warning, giving you time to respond before a small leak becomes a larger issue. Built for real-life basements and utility rooms, it blends a straightforward setup with dependable performance, so you can monitor moisture without hovering over the equipment.

How it works

With solid-state circuitry and a highly sensitive detector, the unit responds to as little as 1/32 inch of water. When moisture is detected, a loud 110 dB alarm sounds, capable of reaching through standard room layouts so you can take action even if you’re upstairs. The robust design emphasizes consistent operation in varying conditions, from cool basements to warm laundry areas.

Key capabilities

• Detects as little as 1/32 inch of water for early warning
• Detachable sensor connected by a 6 ft wire for hard-to-reach spots
• 110 dB alarm is designed to be heard throughout the home
• Solid-state circuitry for stable performance
• Expandable with additional wire beyond 100 ft (24-gauge wire not included)

Flexible placement and expansion

The sensor’s 6 ft lead lets you place it inside a sump pit, near a water heater, or on a wall where moisture would otherwise go unnoticed. If you need broader coverage, you can extend the setup by more than 100 ft with compatible wire, accommodating larger basements or tricky layouts. This flexibility makes it suitable for both small utility spaces and larger layouts.

Real-world use cases

Install in key spots such as near sump pumps, laundry areas, or behind appliances to catch leaks early. Use it as part of a layered water-management approach—combine alerting with a sump pump or dehumidifier for greater awareness. The system provides proactive alerts without implying guaranteed outcomes, offering a practical heads-up when moisture appears.

Ease of setup and ongoing monitoring

Designed for quick installation, the detachable sensor reduces the need to access tight spaces repeatedly. The main unit stays accessible, making routine checks straightforward. This combination supports everyday monitoring in homes with multiple moisture-prone zones.

• Quick, tool-free setup for busy households
• Simple reminders to inspect potential water sources
