SEBSON Water Alarm Mini 10 Year Long Term Lithium Battery | Small Water Detector 60x60x24.2mm, Leak Sensor with Lithium Battery, Set of 2

Excellent devices which really work. The alarm sounded very loudly when we had water ingress and gave me extra time to try to deal with the flooding. I have them placed on the floor by our main doors and they are still working despite being in place for a year or so. They are loud enough to hear when I am upstairs so give great peace of mind.

This is perfect for what I need, it's small and well made and has a high pitched alarm when tested on a damp towel. Another reviewer said it only sounded three time and that was it, but mine sounds three times - on and off until the damp towel was taken away, which would definately wake me. I was worried it might take up too much room, but it is actually smaller and more compact than I expected (which is good!). I have put it under our sink where we've had an issue with leaks, so I no longer need to worry of damage to the kitchen carcass from water damage. I like the fact it has a 10 year long battery and it doesn't take up too much room.

Cheap and cheerful. Does the trick, fired one under the bath

Bought to put in the loft for the water tank as it has overflowed several times due to a fault, checked it before putting it up and it worked fine. Tested it on damp kitchen paper as it said in the instructions and it went off good and loud. Haven't heard it go off as there's not been any overflow so far thank heavens, but I can't see why it won't work like during the test I did. It's quite small so ideal for tight spaces. Edit: This works perfectly and loudly. Highly recommend.

Works fine. Tested with a slightly damp cloth and it beeped loudly until I took the cloth away over a minute later so ignore people saying it beeps briefly then stops. Battery can't be changed , says it's good for 10 years , even if I get half that I'll be happy for the price. Says it will beep occasionally when battery is dying , like a smoke alarm. All good.....happy with my purchase.

Purchased this after our kitchen flooded for the second time this year. The second time our boiler cold feed had burst, leaking behind the kitchen cabinets and going under the floor unbeknownst to us for about a week. Figured I didn't want that happening again and got these. Literally a day after refitting the kitchen and pushing the washing machine back into position, the same evening this little gadget started screaming. Pulled the washing machine back and turned out the waste pipe was slightly blocked leading to overflow - something we'd never have known about until the wood floor absorbed it all up and started showing in front of the washing machine, by which point it'd be too late. Literally paid for itself 50 times over within 24 hours. Brilliant.

I bought this in January following a leak from one of my ventilation units. The unit had overflowed without me realising and water had gone through the floor and in to the ceiling below. Nightmare. Anyway, I had the unit fixed but didn't trust it so purchased this sensor. 11 months later, I've been woken in the middle of the night (why do things always seem to happen at 3am?!) to the sound of loud beeping. It took me a minute to realise what the noise was because I had completely forgotten about it but this little beauty was where I had left it but sitting in a tiny puddle of water. I was able to switch off and drain the ventilation unit. I remember thinking that for such a small thing, the water sensor was pricey but I can tell you it has saved me so much headache this time round. I highly recommend it. Brilliant. Right, now back to sleep!

Bought in 2019. Noticed in 2026 (7 years later) that it had stopped working despite hardly ever triggering the sensor. Took it apart and measured the voltage (battery was completely dead, and is not user replaceable). The circuit board is marked 2016 (10 years ago). So, perhaps the battery does last 10 years as advertised, but it appears that although I bought it new, it was already 3 years old. Thankfully I had tested it, otherwise I might have left it in place expecting it to last a further 3 years.

Thankfully never had a water leakage thusfar, but for a bathroom renovation I had a temporary shower unit placed. Everything is connected to my washers watersupply and I also had to have a contraption installed to allow both shower and washer expell wastewater. I didn't feel safe it would not cause any issues (ie: possibly creating water leaks) I have a smart home solution for a lot of things, but I decided to use this Sebson: They are dirt cheap, they last long, and, most importantly: they are NOT smart devices (so they are totally independent of Wifi network, Bluetooth and Zwave). They just work even if everything is down. Sure, the battery is already active when received, but the units I received have fresh batteries (can't be replaced), but they last 10 years (I expect it will probably be shorter, I am already happy if they 5 years) Just give them a quick test and put them where needed. Forget them for 5 years, and check them again. Done! Point for improving design: the small legs are a bit too high, which means water is detected only if the 2 contacts get wet. As I want to know earlier: I sanded the legs down a bit: They alert me now, even if the leak is slow or just started. Haven't installed 6 yet, but the first three are perfect. Get them, they are cheap. What's not cheap is a leak (and that happens more often than expected!) Edit 02/11/2023: In the mean while we've had a leak behind the tiled over structure holding the toilet, hidden from sight. It was a great help detecting wet concrete. I decided to attach a length if string on top of the housing (not obscuring the buzzer openings) and lowered it down., the string, being long enough, allows me to pull it back up for inspection and testing regularly.

Muy eficaz

Fiat le job.

Semplice, economico e efficace. Suona quando sulla superficie dove si appoggia c'è del liquido. In pratica il liquido chiude un contatto fra due semisfere presenti sul fondo. La batteria interna non è sostituibile, c'è scritto che dura circa 10 anni. E' un'ottima ed economica soluzione, ve la consiglio.
