Topvico Water Leak Detector, 120dB Loud Siren, Powered by 9V Battery (not Include), Sensor Alarm for RV Kitchen Basement Water Heater, 5 Pack

Summary: They're inexpensive (currently $23 for 5) It's loud enough but not piercing, mounts easily, has an on/off switch, and the sensor and alarm can be separated by 37-inches.If you've been in an RV long enough, sooner or later you'll have half-a-dozen incidents where you end up with some kind of water leak. Perhaps a slow-drip under the sink. Perhaps rain works it's way around a seal. Perhaps you left the gray-water drain closed and the shower starts to overflow. Perhaps you didn't use a pressure regulator, so now your sink leaks. Or perhaps you replaced that ugly RV faucet but your install wasn't tight enough so it starts spraying everywhere. Even condensation can sometimes be a problem.Anyway, for RVs (or even homes), I'd suggest placing one near any shower, sink, water-heater, water-pump, water-tank, or water-drain.* Sturdiness & Quality: It looks like an inexpensive manufacture. How well these hold up and work long-term remains to be seen. In a critical area, I installed 2 of these sensors.* Utility: Having an alarm when there's a leak could save you hundreds or thousand of dollars in repairs (and frustration).* Features: It has an on/off switch, a 37-inch cord, makes a loud alarm noise when the sensor is wet, and takes a 9v.* Install: Wipe surface where you'll be securing the alarm with isopropyl alcohol to ensure a good stick. Use cable ties on the cable. Perhaps put the sensor partially under a piece of electrical tape or other tape, while not completely covering the sensor.* Appearance & Material: It's mostly made of a white plastic material, a thin wire, and a simple sensor.* Accessories and Hardware: It comes with some double-sided sticky material which seems like it should hold.* Price: The current price is amazing. $24 for 5. (I think I saw another pack $15 for 3).Because I've only had this a short time, I cannot comment about battery-life or durability. On Sept 21 2023, I have an cheap ACDelco 9v that shows 9.61v, next time I check the battery or when it runs out I'll try to remember to update here.

These are replacing wee little pip squeakers that cost more for much less all around. Easy to put together, very responsive, and loud.

It works as intended, easy install. But the sensor board or head is so light vs. the connected wires, a little difficult to place it flat on the surface by itself.

I got really tired of surprises with water on the floor so I bought these. They were good value for the money. I put one by the washer, one by the hot water heater, by the pressure tank, by an old refrigerator, and they are a water pipe that has a tendency to leak/Break. The alarm is well loud enough that you can hear it upstairs, although I have to say that even when you were standing right beside it, it is not so piercing an alarm that it hurts your ears. But you want it loud enough that you can hear it and this does the job. These are simple to set up and install and I would recommend them for every household. I cannot rate technical support as I have not had to use it so I am leaving those stars blackI got really tired of surprises with water on the floor so I bought these.

It went off right after the garage pipe burst. I immediately knew what it was, went downstairs and shut the house water off. Some water, but not a lot, in the garage due to same pipe that broke in 2023.

These water sensors work well. I got them for my basement, and for under my kitchen sink after I did some DIY plumbing (don’t ask lol). They are very loud as in VERY loud.

These little things are loud! They are super sensitive to water, which is exactly what I wanted...though I have accidentally set them off while spraying cleaner in the vicinity.The ones I ordered initially was missing a single battery cover. I contacted support and they sent replacements right away. Super impressed with the seller.

I bought these for our grandson. They are great to give you a heads up on a leak. Great idea.

Cheap and simple water detector.I marked on position with a green dot. Also marked battery orientation with red and black marker. I didn’t use the provided double stick tape. I instead used the 3m hook n loop Velcro so I could easily remove. The unit is very loud. The sensing head is pretty sensitive if it creates problems I’ll just remove it and use just the two wires to complete the circuit. Only complaint so far is the sensor wire could be longer and could come out of bottom of sensor pack. Didn’t make any sense to go up out of top to end up going down to water sensing area.

Useful and of high function to protect you from long and expensive repairs if there was a leak and you were not aware for a while on cabinets and flooring. Very easy to install.

They do appear to be rather lightweight, but they work perfectly and come with double sided tape for mounting. Loud too with an on / off switch. Tested each before mounting and no problems. Great for those out of the way places. Mounted mine under the sinks and in the floor tray for my water tank which is hidden away. Only had them a couple of months so can't comment on battery life, but no reason to suspect it will drain power unless activated. A little tip on mounting the sensor; I cut a small piece of paper towel and wrapped this a couple of times around the sensor and then duct taped this to the surface - See pic.

A must have product in homes and condo apartments. Any slight water leakage is detected instantaneously and warning sound is quite audible

These are great they're very loud one drop of water and the alarm goes off.

Sonne fort et semble de bonne qualité.
