Our verdict

Flood Buzz Water Leak Alarms suits anyone who wants to hear about water rather than manage a monitored security system, because monitoring is $0 a month on a contract of 0 months. It is a purpose built leak alarm, not a hub, a camera or a response service.

Pros and cons

Pros

  • The alarm is loud and audible with no app and no subscription, and it runs on battery power, so it can sit on a water heater pan without a socket.
  • Monitoring is $0 a month on a contract of 0 months, so the cost at renewal matches the cost at entry.
  • Installation is not required and the model is diy, so it suits renters and anyone who will not book a callout.
  • Support runs on phone and help centre, so setup questions have a phone route rather than only online documentation.

Cons

  • Professional monitoring is no, so the alarm depends on someone nearby hearing it; SimpliSafe covers a wider set of risks through alarm, camera and video doorbell.
  • Product types come to alarm, so there is no camera, video doorbell or smoke alarm here to add to the kit.
  • Support is limited to phone and help centre, so there is no live chat or email route for a question between calls.
  • The money back period is 0 days, so there is no trial window to hear the alarm in a real room before deciding.

Who it suits

  • Homeowners and renters protecting a water heater, washing machine or dishwasher, where the alarm only has to be heard.
  • DIY installers, since installation is not required and the model is diy.
  • Anyone who wants no recurring charge, with monitoring at $0 a month and a contract of 0 months.

Who should look elsewhere

  • Not for people who want cameras, video doorbells or smoke alarms in one kit: SimpliSafe lists those in its alarm, camera and video doorbell.
  • Not for the lowest possible spend: The Home Security Superstore lists $13.95, below the Flood Buzz alarm.

Pricing

The Flood Buzz Blue water leak alarm for water heater pans costs $19.99 up front, and it is the whole cost. Since the contract is 0 months and monitoring is $0 a month, the entry price and the renewal price are the same number, so there is no introductory rate that expires and nothing to cancel later. The plan is the only plan on offer.

What it does well

Product types come to alarm, which tells you where this brand draws its line. Installation required is no, so a unit can sit on a water heater pan the day it arrives, and professional monitoring is no, so the plan is built around an alarm you hear rather than a service you pay for. The range is narrow, and the pitch is that nothing else is needed to make it work.

Where it sits among rivals

Price is the only measure that stands out against the field. Flood Buzz ranks 8 of 70 on price, while it sits at 1 of 60 on contract months and 1 of 51 on monthly monitoring. Cheaper hardware exists, yet few alarm systems here cost less to keep switched on year after year.

Who runs it

Flood Buzz is run by Goodscharfenterprises LLC, headquartered in the United States and trading since 2010. Support runs on phone and help centre, so help arrives by phone or through the help centre rather than live chat. Orders, refunds and terms are handled by that company, which is the name to look for on the refund policy and the terms pages.

How Flood Buzz Water Leak Alarms compares

Frequently asked questions

How much is a Flood Buzz water leak alarm?+

The Flood Buzz Blue water leak alarm costs $19.99. That is the whole outlay, because monitoring is $0 a month and there is nothing extra to buy, no hub and no app. You buy the alarm, place it, and it works.

Is there a monthly fee or a contract to renew?+

Monitoring is $0 a month and the contract is 0 months, so there is no subscription fee to renew and nothing to cancel. The price you pay covers the alarm from the day it arrives, which suits anyone tired of recurring charges.

Does Flood Buzz monitor the alarm for you?+

Professional monitoring is no, and the product line covers alarm only, so nobody is dispatched when water appears. The alarm sounds where it sits and that is the whole response. SimpliSafe is the alternative to consider if someone else answering the alert matters to you.

Do I need an installer, wiring or an app?+

Installation required is no and the model is diy, so there is no engineer to book and no hub to wire in. The unit runs on battery power, which suits a water heater pan or the space under a sink where a socket is rarely close by.

What does the device actually cover?+

Product types are alarm, so coverage stops at water. The device is a loud audible leak alarm with no app and no subscription, which means it will not tell you the leak has been fixed or shut off your water. Cameras, video doorbells and smoke detection sit outside what this brand sells.

How do I get help after buying?+

Support runs on phone and help centre, so help comes by phone or through the help centre, not live chat. Placement questions and fault alarms can be taken on either route, and the help centre gives you something to read before you call.

Who is behind Flood Buzz and where are they based?+

The brand is operated by Goodscharfenterprises LLC, based in the United States and trading since 2010. Trading terms and returns sit with that company, so the refund policy is written against it rather than a separate trading name, which is worth reading before you order.

How does the price compare with other alarm brands?+

Flood Buzz sits at 8 of 70 on price in this comparison, so it is not the cheapest route to a leak alarm. The Home Security Superstore lists $13.95 and SONOFF lists €20.47 for its camera. The saving on Flood Buzz is that nothing is added later.
