Essential Info

Water leaks often occur in areas that are hard to see right away, behind appliances or in areas of your home that may not be used often. Undetected water leaks can end up causing thousands of dollars in damage. Protect your home from potential water damage by keeping a Smarthome SELECT Water Leak Detection Alarm anywhere flooding is a potential danger - near the refrigerator, washing machine, dishwasher, toilet, sink, or water heater. For added peace of mind, consider using one near aquariums, sump pumps, or in the basement and garage. When the unit detects water, it sounds a loud alarm so you'll know instantly when and where the excess water is. The small size and wireless, battery-powered design allow it to fit in tight spaces and anywhere water could possibly leak and collect in your home.


What's Included

  • 1x - Water leak detector
  • 1x - 9-Volt Battery
  • 1x - Owner's Manual

  • More Info

    Place the Smarthome Water Leak Detection Alarm flat or upright, so it can fit easily and discreetly in almost all locations. When water is detected by the metal sensors, the 95db alarm will sound for up to 72 hours.

    The alarm will also sound and the LED light will be activated when the battery gets low. Battery life when in constant alarm mode is three days. Under regular use the battery life is over one year, however annual battery checks are recommended.

    Smarthome recommends placing at least one Water Leak Detection Alarm in every bathroom, in the kitchen, by your water heater and close to your washing machine.

    I ordered 3, one for under the dishwasher, one for the washing machine and one for the hot water heater. One did not work. I even exchanged the battery from a working one and it still didn't work. Placed the nonworking alarms battery in a working alarm. That battery was dead. Haven't contacted company on return yet. Too much on the plate to worry about $20. Just disappointed

    It's a great device! Wish I would have had it before my dishwasher reined my hardwood floors!
    EARNEST -- conroe, TX   3/29/2014
    Batteries lasted about 2 weeks before the alarms started beeping. Hopefully it was because the batteries were old/bad and not because they were drained so rapidly
    VICTOR -- los angeles, CA   2/16/2014
    It works as expected, but if water drips on top of it then may go through the speaker holes and may damage the unit. I have not tested for that, it also should have an indicator on which side/s to pry it open for battery replacement.

    can save a ton of damage - a must have for saving floors
    CONNIE -- riverside, CA   1/11/2014
    haven't used yet
    Mike -- Maryland   12/5/2013
    A good inexpensive product; however, it does have 1 design flaw. When the battery needs to be replaced the unit alarms continuously exactly the same way as if it has detected a leak. Typically, battery operated units will chirp when the battery needs to be replaced, not this device! This may not seem like that big of an issue... but... when it happens at 3am, which it will, it is!
    TED E -- pocatello, ID   12/1/2013
    Product is just as advertised. it works great.
    EDWARD -- west palm beach, FL   11/4/2013
    Excellent product. Works as advertised. A "must" for those looking to avoid major flood damage from leaks.
    ROBIN -- hopkinsville, KY   8/30/2013
    Really easy to install and priced right.
    DOUG -- shadow hills, CA   6/27/2013
    Easy to put battery in. Nice that you can test to make sure it is working by putting your fingers across the sensor (you get a sound). Small, discrete, nice design.
    WILLIAM -- oklahoma city, OK   6/9/2013
    Works as advertised. I'm very satisfied and would recommend this to all.
    ELIZABETH M -- las vegas, NV   2/16/2013
    I've heard horror stories from friends who had leaks that caused massive damage before they were discovered. These alarms can save a homeowner big bucks and a lot of inconvenience. I put them under sinks, by the hot water heater and behind my washing machine.
    ALEX -- monrovia, CA   2/14/2013
    How appropriate that i receive this request to review today the day the water detector went into alarm. I had the sensor placed under my kitchen sink and it detected a small leak. Excellent buy!!!!! *****
    ALAN -- new deal, TX   1/27/2013
    Works great and will likely last a long time on a 9v battery. Very loud, which could be a good thing.
    DONALD -- helena, MT   1/26/2013
    The item was backordered but I was kept up to date as when it should be shipped. Good service. Thank you.
    KATHERINE -- irvine, CA   1/26/2013
    Great product. The alarm went off within seconds of putting it under the kitchen sink, detecting an unknown leak.
    Jose Bravo -- United States   1/15/2013
    Pros: it works and it detected a leak already for me once in my kitchen sink area Cons: i tried going ahead with the package battery and ended up being awakened at 5am in the morning due to low battery a little after two months or so. So advise to install initially some good battery types prior to putting in place. In my case, i had to climb into the attic to retrieve and pull bad battery which was a little inconvenient.
    J LINDSAY -- san diego, CA   11/8/2012
    Well-made item, looks as though it will last some time. I can't say how well it works to detect a leak because (luckily) we haven't had one, but certainly as soon as you lay your finger across the two metal contacts, the alarm emits a loud shriek that would be hard to miss. It also has a low battery warning, which is good. I bought 3 of them; no regrets at all, I'd recommend them.
    KENDAL -- el cajon, CA   10/25/2012
    Very very impressed! Had two floods within three months that caused several thousand dollars in damage at my home. I purchased 10 of these so I never have another problem! I put one everywhere there is water.
