Honeywell Water-Sensing Alarm

The water defense water-sensing alarm detects leaks near major appliances around the home or office.
View larger.
Features
The water-sensing cable detects dampness along its entire 4-foot length and can be easily tucked away near appliances or hidden under baseboards around carpet. A separate RWD41-compatible 8-foot extension cable (the RWD80) is available for an even more comprehensive range. The base unit (powered by a 9-volt battery, not included) can be mounted on a wall or another flat surface and comes with a 6-foot leader cable. Installation is a cinch thanks to plug-and-play features built into the system: Just add batteries, plug in the leader cable and the water-sensing cable, and mount the base unit with two-sided tape (which the securing clips also employ to hold the water-sensing cable in place). An 80-decible alert sounds when water is detected, permitting for early discovery and intervention of leaks, and can be turned off by wiping the sensor cable with a dry cloth.


Leak Detection and Protection
Water damage is the second-leading cause of home insurance claims nationwide, and 80 percent of all home water claims are caused by plumbing and major appliances. A surprisingly large amount of water can escape from the smallest of cracks--a 1/8-inch crack in a pipe can release up to 250 gallons of water a day. Insurance companies recommend the installation of water-detection systems like the RWD41 as the best protection against the potentially expensive and stressful damage caused by leaks.

What a peace of mind to have this product.
Paresh Shah
I was able to hear it while I was awake, but don't know if it will be loud enough to wake me if I'm asleep.

You can attach the included cable, or buy a longer extension.

I had read reviews critical of the alarm volume. How correct they were. The alarm volume is much too low, and does not even come close to that of a typical smoke alarm. The concept of water-sensitive wire/rope circling the appliance (water heater, sump pump, furnace humidifier, etc.) triggering the alarm when wet, is very good--and it is quite sensitive. But hearing the alarm is another thing. I pondered keeping the system because it could be barely heard from the basement unfinished area to the finished area, especially if noise was present, but since I pass in front of it several times a day, I figured I would eventually hear it. Consequently, I may not hear the alarm when I should. Honeywell needs to greatly improve the alarm volume. I would not recommend this alarm if distances or room closures are more than one room apart.

This alarm is ridiculously easy to install. It took maybe 15 minutes (tops) to put it under a bathroom sink, including attaching the cable to the drainpipe. It may take longer to snake the cable behind a washing machine, but it's still really easy.

The cable is very sensitive, and the alarm sounds within a couple of seconds of the cable getting wet. When you dry the cable, it takes less than a second for the alarm to go silent. The alarm is LOUD - loud enough to wake you up.

Like a smoke detector, this alarm just sits there silently, doing its thing, and you never know it's working until ... well, until it works. You should probably test it once a year by wrapping a wet cloth around the cable or dunking it in a cup of water.

Vine Customer Review of Free Product ( What's this? )
Water leaks can be a very serious problem that can dramatically damage property. Unfortunately, most water leaks happen in out-of-sight places, and are therefore hard to detect and manage. In such cases a good water detector can go a long way in easing your mind and helping you prevent serious water destruction.

This Honeywell water alarm is well designed and works just as advertised. It's a self-contained unit that can be installed virtually anywhere. It runs on a 9V battery, just like most smoke detectors. However, unlike smoke detectors it doesn't come with a button that will let you know if the battery is dead. This may be a problem if your water detector is located in a hard to reach place.

The detector can be mounted either on a mounting hook (not included) or using the self-adhesive double-sided tape (included). The problem with the latter mounting option is that if you place the detector in some inaccessible place, then you'll have a hard time replacing the battery later on. Thanks to its squareish shape, the detector can also be placed flat on any level surface, which is the setup that I have chosen to go with.

The detector comes with a 4 ft. (1.2 m) leak detection cable, which is barely adequate for covering a small area. It also comes with the 6 ft. (1.8 m) leader connection that can substantially extend the detection coverage area. In fact, the leak detection cable is expandable p to 240 ft., a sufficient length that can cover a perimeter of any large room. The cables are flexible, but they are not very pliable, i.e. they won't easily conform to a shape that you would like them to be in. The cable comes with cable securing clips though, and these can be used to arrange the cable into the desirable shape.

Vine Customer Review of Free Product ( What's this? )
Currently we use spot water detectors in various areas of our home...under our kitchen sink, near our water heater and a few areas in our basement. Compared to the spot water detectors, I absolutely love the coverage area of this water detector. This unit has 4' of water detection cable which isn't a lot, but additional cable can be purchased to cover 240'...enough cable to potentially cover the perimeter of an average sized basement.

Off & on we've encountered water problems in our basement....at least 3 times when our water heater broke & a few other when there was exceptional flooding in our area. This cable would've alerted us to the problems...however, it's not loud enough to be heard upstairs. Our basement steps are located in the garage...so there's no basement door that can be left open to hear any 'basement sounds.' I've been known to put my ear to a register when I hear noises downstairs. Thankfully, we haven't had any water issues since I received this water sensor. So I put water on the cable myself, & dried the cable to stop the alarm. However to stop the alarm in a real-life situation, it might work better to disconnect the sensor/water detector cable from the unit, and if that doesn't work, you'll have to remove the battery.

Purchasing extension cable will make this unit more useful. Honeywell RWD80/T Water Defense Water Sensing Alarm Extension Cable

This sensor is easy to set-up and install. Double stick tape is included to mount the alarm unit on a dry wall & there's 6' of leader connection cable (we can mount the alarm close to the basement ceiling & possibly better hear the alarm in our living area.
