12 best water overflow alarms

Water overflow alarms are devices designed to alert homeowners to potential water leaks or overflows in their homes. These alarms are typically used in areas prone to water damage, such as basements, laundry rooms, bathrooms, and kitchens. Here's what you need to know about water overflow alarms:

  1. Function and Purpose:

    • Water overflow alarms are designed to detect the presence of water where it shouldn't be, such as a flooded basement or a leaking appliance.
    • When water is detected, the alarm emits a loud sound, typically in the form of a siren or a loud beep, to alert the homeowner to the issue.
  2. Types of Water Overflow Alarms:

    • Floor Sensors: These alarms consist of sensors or probes that are placed on the floor in areas where leaks or overflows are likely to occur. When water comes into contact with the sensor, it triggers the alarm.
    • Floating Sensors: Some water overflow alarms use floating sensors that are placed in areas prone to flooding. When the sensor rises due to water contact, it activates the alarm.
    • Wi-Fi/Smart Alarms: Modern water overflow alarms may connect to Wi-Fi networks and send alerts to your smartphone or other devices when a water issue is detected. They may also offer additional features like app control and remote monitoring.
  3. Installation and Placement:

    • Water overflow alarms are typically easy to install and do not require professional assistance.
    • Place the alarms in strategic locations where water leaks are likely to occur, such as near water heaters, washing machines, sinks, and basement sump pumps.
  4. Benefits:

    • Early Detection: Water overflow alarms provide early detection of leaks or floods, allowing homeowners to take prompt action to mitigate water damage.
    • Prevents Costly Damage: Timely alerts can prevent costly damage to your home's structure and belongings.
    • Peace of Mind: Knowing that you have a water overflow alarm in place can offer peace of mind, especially when you are away from home.
  5. Maintenance:

    • Regularly check the alarms to ensure they are functioning correctly. Test them by simulating a water leak to verify that the alarm sounds as expected.
    • If the alarm uses batteries, replace them according to the manufacturer's recommendations.
  6. Brand and Model Varieties:

    • There are various brands and models of water overflow alarms available, offering different features and price points.
    • Some models may come with additional features like adjustable sensitivity settings and low-battery indicators.

Water overflow alarms are an essential tool for homeowners to prevent water damage and the associated costs and inconveniences. By placing these alarms in key areas of your home, you can take proactive steps to protect your property and belongings from water-related disasters.

User questions & answers

Question: How do I stop this thing from sounding the alarm after testing it
Answer: The form of the i4618AC is physically different from that of the 120-538B. It has a different electrical connector, and a different mounting base. It you are handy with household electricity, then it is not difficult to swap out - takes about 30 minutes. Otherwise, you will need an electrician (and $100 for that).
Question: How long will the alarm sound once water is detected
Answer: Yes, I think so even though I haven’t tried
Question: What is the size of the sensor itself? I need to drill a hole in the cover of a sealed sump pump and need to know how big that hole would be
Answer: Hi, it is available at a different listing here is the asin to get to it: B01BLQKY7A
Question: Your descriptions below pictures 2 and 3 are reversed
Answer: I can only guess. They are in bubble wrap to protect it. In stores they need to be in a blister pack most likely to prevent theft.

User questions & answers

Question: what is size of sensor
Answer: I do not know if these two items are the same. I'm sorry that I cannot be of assistance,
Question: is it easy to reset
Answer: According to customer service at Kidde, the FireX FADC reccomended Kidde replacement options are the i4618, the i5000 and the i12060, with the i4618 and i5000 being the preferred models. However other people at Kidde say that practically all Kidde's will replace the FADC, but you may have to swap the wiring harness, pretty simple if you can run a breaker box and a wire nut. I would call the help desk at 1-800-888-6788 to verify your present situation. Make sure you have the model NFO, of course, and the manufacturing date stamped on the back.
Question: if the battery is low, will it give you some sort of audible/intermitten beep warning (like a smoke alarm
Answer: It does not.
Question: How do you splice in more wires to create a dual sensor using the one box? Want to put 1 box and 2 sensors in a tight location
Answer: Is i4618 interchangeable with Firex 120-1072? Can I attach to the same base?

User questions & answers

Question: Can you make sensor wire longer, and details
Answer: Hello, we do not have instructions or knowledge of how to lengthen the wire. The warranty will be voided if product is altered or tampered with. Thanks
Question: how long will the batteries last (assuming it is rarely alarming
Answer: Been around 6 months and it has gone off around 20 times and batteries are still a full charge. This is the loudest alarm I have for the price.
Question: Is this magnetic or does it use adhesive to attach to appliances? The video says it's magnetic but the descripton says it uses adhesive
Answer: The unit I have attaches via adhesive. Bottom Line: neither magnetic or adhesive makes any difference. You want the sensor to be as low on the ground as you can get it so it reads water at the first appearance. I used extreme tape over my sensor to force the unit to stay flat on the ground at the lowest point (my garage has a little dip in the cement floor). If you have magnetic and it causes the sensor to sit 1/8" off the ground, you will have a lot of water loss before the alarm goes off. An adhesive patch could also lift the sensor off the ground by 1/16" also.
Question: Can the alarm be switched off once it goes off while you fix the problem
Answer: Yes, the alarm has an off and on switch. You can remove it from the water, turn it off, and it will reset itself.

User questions & answers

Question: Can it connect to WiFi
Answer: 2-1/2" X 1" X 1/8" plastic plate. there are 2 metal discs a little smaller than a dime fixed to that plate. There is a 10 feet long wire would up inside the case that attaches the sensor to the case. The case has 2 holes on the back to mount on wall if you want to do that. There are two mounting holes in the sensor plastic plate if you want to mount that, such as with any tiny screws you happen to have. The instructions say you can splice up to 100 feet of wire onto the 10 feet wire in order to have the alarm somewhere far away from where the sensors are placed. Teeny tiny wire is OK to use since the voltage is only 9 volts.
Question: Is this water alarm sensor with wifi with shutoff
Answer: To reset all you have to do is dry the leads and it will stop alarming. Please contact us directly if you are in need of further assistance at 800.911.0466 ext 3. We are open M-F 9-5 CST and would love to assist you.
Question: What does the sound sound like
Answer: There is no low battery alarm. We recommend that you change it out with a good quality battery once a year. Please contact us at 800.991.0466 ext 3 for tech support. M-F 9-5 CST for additional assistance.
Question: A comment says the alarm only lasts for 1 minute. Is this true? I want the alarm to sound as long as there is water
Answer: For the price, why splice wires, the leads can be extended to 6 feet. What I would recommend is to place the sensor on a sheet of paper towel. Any moisture will wick up to the contacts. Also you can cover a bigger area where just a corner of the paper towel will transfer the liquid by capillary action to the contacts.

User questions & answers

Question: which works best for condensation on the furnace -air handler
Answer: Although this is a question best answered by First alert, I believe that once it is synced with other modules it only sends a notification to other modules when you either push the test button or an actual alarm triggers a signal to be sent. Anything else would likely cause excess battery drain for no reason.
Question: Is it water proof? Meaning if it is submerged in several inches of water can it be reused
Answer: I mixed sa511 smoke with voice and sco500 smoke and co with voice and all work fine together
Question: Is the battery replaceable ? If yes, what size battery does it require
Answer: Here is the wording from the instructions: The communication distance (range) between any two ONELINK® Alarms is typically 50 feet (15 meters) inside of a home. Some features of a home, such as the number of floors, number/size of rooms, furniture and types of building materials used may reduce the range of the Alarms. Examples include: suspended ceilings, ductwork, large metallic appliances (refrigerators) and metal studs. A feature of ONELINK® Alarms is that they operate as a mesh network. All Alarms will repeat any alarm signal that is received to all other ONELINK® Alarms. Interference from structural conditions can be overcome by adding additional Alarms to route the wireless signal around obstructions. • The range and proper operation of any wireless device will vary depending on its surroundings. It is very important that each Alarm is tested individually before and after installation to make sure that all Alarms respond properly.
Question: Does it float
Answer: They should, I have 4 units and was able to get them all connected. It took me a few times at the beginning because I was not fast enough.

User questions & answers

Question: So which is the correct db level? 120db? or as stated in the heading, 130db? makes me question other claims of accuracy
Answer: input 9v
Question: can the wire length be increased from 36 inches (3 ft) to 50 ft
Answer: This sensor came with the battery glued in so hard I couldn’t get it out. It wasn’t hooked up and when I tried to move the battery I broke one of the small wires off and so it never worked. I would say find a different make and model
Question: I'm going to guess this little copper looking piece needs to be on the floor where water might be? Zero instructions
Answer: Its working voltage is 9V, working current is 300mA
Question: does it have a low battery alarm, warning that battery is getting low
Answer: It can be directly put into the water tank without fixing

User questions & answers

Question: can more than one detecter be set up from one house to the same wifi alert app
Answer: It works on the fact that water is a conductor, so a continuous layer of water touching the 2 sensors will complete the electric circuit and sound the alarm. So it depends on how wet your carpet is. If the carpet is wet enough for the water layer to be continuous, then it should sound the alarm, but if it's not wet throughout the carpet, then it won't. (Based on my general knowledge.)
Question: Can siren be turned off? Wifi detection/notification only
Answer: My bug did the same thing after 3 months. It sounds like the new batteries you bought are not new. I had mine under my dishwasher where it was hard to get to so I just quit using mine and got another leak detector that is supposed to only turn on the alarm if they dissolve.I don't think these leak bugs are worth having.
