Defend against water damage
Help protect the things — and people — that matter most from leaks and water damage. Place a Water Leak Alarm near the usual suspects — water heaters, sinks, bathrooms — to help stay ahead of water leaks.
-
Be a step ahead of leaks
Be notified of a potential water leak at your house by placing the detector near any appliance where there is a chance of disaster including water heaters, sump pumps, sinks, toilets and dishwashers.
-
Warning at the first drop
This water sensor and alarm can detect water only 1/16" deep. Upon sensing a potential leak, the alarm will sound for up to 24 hours (depending on battery life) on a volume of 85db.
-
Mind the Chirp
The water leak alarm provides a chirp alert to remind you it's time to change the 9V battery (not included). No chirp? You know your water leak detector is operating at peak performance.
-
Reusable
Resettable for re-use once alarm sounds. Simply dry off leak detector, clean up water and replace.

There was a problem filtering reviews right now. Please try again later.
The packaging is 1 star in my view because of the overly thick plastic you have to cut through to get at the product, and then the 5 minutes or so of time you will spend if you want to get all the double stick tape goo off the bottom of the unit. Have your Goo Gone ready! This is not a big deal of course, and doesn't affect my rating.
Some people wrote it wobbles on the base. That only happens if you don't screw the base in all the way. It is easy to screw in all the way if you use a quarter in the slot to turn the base cover. I wonder if this was the issue for some other reviewers that stated it didn't go off at all or the alarm was delayed, since not screwing the base in all the way moves the electrodes up off the floor. This could be a significant distance off the floor if the unit also rocks on the base such that the electrodes are even higher. But there is no issue here if you screw the base in properly.
One final note is I agree the wires for the battery attachment are a bit short, but if you are careful there shouldn't be an issue.
It will detect even the slightest water and is loud. Make sure to put it on a flat portion of the basement floor and consider the path where the water will flow so that you can catch it as early as possible. Mine is sitting right next to my sump hole. Also beware that if you have cats, they might play with it and move it. Check the batteries often. So far batteries are lasting about 6 months for me.
The downside is that in many cases, if this alarm works, and the water is flowing in quickly enough, it's going to make a mess either way, because you won't be able to address it quickly enough. However, it could help prevent a MAJOR flood. Have a plan! Back up power and additional pump on standby. I have a generator and even a coiled up extension and AC inverter hanging on the wall in case I need to use my truck for power!

al principio tenia mis dudas sobre comprar uno de 85 db o uno de 100 db.
Pues este es de 85 db y se escucha fuerte y claro desde cualquier parte de mi casa, al mínimo contacto de los sensores con el agua
