Best water leak detectors FAQs

Are water leak detectors worth it?

Water leak detectors can save you money in the long run, both from water damage and from a sudden increase in your water bill. Water leaks usually go unseen for a while before causing noticeable damage in your home.

How do water leak detectors work?

Water leak detectors monitor water flow, either by counting the amount of water flowing through the system directly connected to a water supply line or sonically recording it through using an ultrasonic emitter. Some detectors also have a water shutoff valve that can cut off water when they sense an increase in moisture.

Where should water leak detectors be placed?

You should place water leak detectors anywhere you think you might be prone to flooding. Good placement of water leak detectors would be near washing machines, in basements, in bathrooms and under the refrigerator.
