Water Alarm, with 6 ft Extended Sensor Sensor for Water Leakage Detection, 110dB Audio Sensitive Flood Alarm, Battery Included, LA Homieta WA08

I haven't had it long but so far, so good. It works, even if I just lay a wet finger across the sensors, and I like the design.In case the description or other reviews haven't made it obvious, it comes assembled as a single unit but the bottom of the plastic box - the side with the sensors - separates so you can either stand the entire unit on the floor, sensors down, or detach the sensor plate to put it where water might be and keep the larger box elsewhere. I should point out that 'elsewhere' in this case means up to about 6 feet away because the two parts are connected by wire, but this is helpful because the main unit is NOT waterproof.I was disappointed by this at first because I needed to put it under the trap under my kitchen sink and any water would drip onto and potentially through the non-waterproof innards before it gets to the sensors, but since the two parts can be separated it's not an issue. The main unit has keyholes on the back so I was able to easily mount it to the side wall inside the cabinet under the sink.On that note, I do have one small complaint. The box the unit comes in has a template printed on the inside that you ought to be able to cut out and then use to mark where the holes should go for screws if you're going to mount the main unit. Unfortunately, the template is not to scale so other than the fact that it says the holes/screws need to be 2 5/16 inches apart, it's useless. On the other hand, if the template hadn't been there I wouldn't be complaining about it, I would have just measured between the keyholes on the back of the unit and mounted it without a template...like I did. So, a very minor complaint.I know it detects water so I just need to wait to see whether it lasts and whether it really does beep to indicate when the battery is low as advertised. Fingers crossed.Edit - 26 Feb 2018: It definitely works. A leak started exactly where I expected it might and the thing started screaming! It was so loud my cat hid at the other end of the house until I pulled the battery. Still no idea whether it also goes off when the battery is low. That update will have to wait.Edit - 7 Nov 2019: It still works. I know because I just tested it to see if the battery was dead. It's still using the original battery I installed two years ago and I should probably change it once a year like I do with my smoke detectors but I really want to find out whether the low battery warning works. Maybe I'll be able to comment on that one of these days...or years.Edit - 2 Sep 2020: I can finally report that the low battery warning works. I was going nuts for a couple days trying to figure out which of my smoke alarms was chirping. Didn't make any sense, especially since the chirping was 100% consistent but every 25 1/2 minutes. Don't ask me how I know that detail... I wouldn't mention this but I figure it might spare someone else the same maddening experience. Remember: one chirp every 25 1/2 minutes (though your mileage may vary). The original battery lasted nearly 3 years even though it had spent some time alarming (see my 2018 edit). I replaced the battery and laid one finger across the sensors and it worked immediately. Still going strong!

It really works. Glad I got it when I did because within three days a washer overflowed. However it could use a better system of turning the alarm off once it's triggered. Had to pull it off the wall, open the battery cover, get the battery out (which is no small feat) and unhook it from the wires to turn it off. Then you have to wait until it dries to put it back together and put it back up. That was a bit of a pain. On the other hand I'm super glad I have it.

I've only had these for a week. Installed with my new sump pump & check valve. These alarms very sensitive to moisture contact. Your slightly damp finger across the contacts will send out a hair curling, screeching LOUD alarm.It's been a really wet October here, 5 plus inches of rain in the first 11 days of October. Anyway, having 3 of these I also installed one at my parent's home the same day as my installation. A week later their alarm went off on a Sunday afternoon, the shaft of their pedestal sump pump was split in two, catastrophic pump failure. That alarm saved a huge mess in their finished basement and allowed plenty of time for me to procure a new sump pump and get it installed before breaching the rim of the sump pit.Can't comment on battery life yet but if I get 3 years, manufacture states 5yrs, on a single 9V battery, oh yeah baby!My one and only con, wish there was an off switch. I installed using the contacts mounted to a SS rod suspended into the pit 9" below the rim. The rod is hooked to the head pipe so if the alarm goes off the contact are easily lifted out of the water.

The design and easy use of this device makes it, IMHO, worth its weight in gold!Put in the battery, put it in the place where there is the potential for a water leak.In my case, it is a closet in which we have out water heater, There is a 6-foot or so wire with a sensor that you place face down on the floor. The sensor has two leads. If there is a leak, the water, by touching both leads, closes the circuit, and the alarms begins to sound. Since we don't regularly use the closet in question, if that water heater did begin to leak, it would take a good while before we noticed, and after a lot of water damage had been done.For a modest investment, this Water Alarm gives you a GREAT return on that investment!
