Zircon 63931 Electronic Water Leak Detector with Batteries Included

LK: Works well but you have to supply the batteries.
Which would have been fine should they have not said in the write up..." comes with batteries"...
Doesn't.

Mark W.: I've had one of these alarms at every point of potential leakage for the last 9 years. Sinks, laundry, water main, Central air, and boiler. These saved me several times from what could potentially have been costly repairs. One time, during a heavy storm, it alerted me that water was starting to flood the basement because my sump pump failed. The combined sound of 3 alarms going off woke me up from 2 floors above. I was able to get down and throw in my backup pump before any real damage occurred.

Donna L Williams: High pitch for noise level, battery to be tested yearly JIC. If a water leak occurs, being present in the home is great notification, however if you're away from the home, there is no alternative method to alert you that there is a water leak.

Reality Check: Having a leaking water pipe in a part of the house that sometimes goes unnoticed for several days, I decided I needed a few good water alarms.

After reading the reviews on both the Zircon and First Alert models, I decided to purchase a three-pack of each, the First alert being about a buck more apiece.

Each brand included batteries and they are about the same physical size. Each operates in the same method, with the unit placed on the floor or other location likely to be flooded with the sensors at the bottom. The Zircon actually sits on it's back (flat side down) and the First Alert on its bottom (smallest side down). After a careful study of each, I think that the Zircon in a better choice for several reasons:

- The Zircon will actually float and keep operating if situated properly

- While both models seems to have an alarm about equally loud, the Zircon is a pulsating pitch, which to me would be more noticeable. The First Alert has a constant single pitch high alarm. In a remote location where the sound would be diminished, it would be less noticeable, blending in with background noise like planes or appliances.

-The First Alert comes in a...

Blind Faith 99: I've been using these alarms for about three years. They work so well that today I bought three more on a Lightning Deal at Amazon. I put them everywhere. The alarm is loud. My neighbor even once heard it and came over to ask what was going on. I guess if you're several rooms away with closed doors, you might not be able to hear it. If that's your concern, then maybe you should go to a more sophisticated industrial-type alarm that's perhaps wired into remote speakers. If you hold the alarm in your hand and touch the contacts with anything moist, for me the sound is ear-piercing -- loud enough that I will hold my thumb over the speaker hole to muffle the sound. I just don't think the loudness of the alarm is an issue, unless you're in a large house or building, or otherwise far away from where the alarm is. The alarm will go off with the slightest moisture touching the contacts. The only way to turn it off -- aside from opening the device and disconnecting the battery (those rectangularish 9 volt ones) -- is to dry off the contacts. Much of the time that can be done easily. If water gets under the contacts, sometimes it takes a half minute or longer to get them dry. To speed up the...
