Q: What is the best water leak detector?

A: A Glentronics leak detector is versatile and can be used in any room. It can detect as little as 1/32 of an inch of water. The alarm sounds for up to three days if it detects a leak. The Glentronics Watchdog has a 110-decibel alert sound, which makes it louder than many of the more costly water leak detectors available.

Q: What is a leak detection sensor for water heater?

A: Water sensors detect and prevent excess moisture and flooding caused by broken pipes and faulty appliances. A leak detection system is made of sensors, shut-off valves and a centralized hub. The sensors are placed in areas where leaks are common, such as near faucets and beneath water heaters.

Q: Can you put a water alarm under a sink?

A: You can put them under sinks or near water heaters, sump pumps, dishwashers, water filtration units and plumbing outlets. The device triggers an alarm when it comes in contact with water. Reviewers describe the 85-decibel alarm sound as a “pulsating pitch” that is about as noticeable as a smoke alarm.
