## Description

Rialco 84010 Flood Alarm with 11 inch Sensor; 1-Pack - - - The 11-inch long Flexible Sensor Arm on this well engineered alarm device can be easily bent to Reach into small, awkward spaces and sense the presence of water - - - Locating the sensor near low floor drains will detect when water backs up in a flooding situation - - - Also can be used to detect overfilling of tubs, pools, sinks, etc and hot or cold water tank leaks - - - A great, dependable, economical solution to detecting leaks and floods !!

Review: Simple and works fine. - These are best suited for hanging as shown, rather than floors or flat surfaces (IMHO). Mine worked well in my tests and is a bit louder than some. Decent value for the price, I think. This design is a bit different than most others and well suited for hanging on a tub or basin (or whatever) to prevent overflow. Can also be used for leak detection, but the wire is very stiff, so in some situations the simpler, "just sit it down on the floor" designs are easier to use. But this is better if you need to feed the "detector" into an enclosed area or pan.
Review: Had it for three months now, works, good value, instant set up. - This seems too good to be true, but it is. Just take it out of the box, put the batteries in correctly and put it on the floor where you are nervous about flooding. It makes a nice loud alarm when the contact at the end of the flexible sensor arm gets wet. Simple, effective. I've tested mine several times, works great. I consider the alarm loud enough to wake me, but not loud enough to alert a neighbor if I am not home. I bought two of these for my tub area and washing machine area (I live on a condo third floor). To be extra safe I bought two different units (similar in overall function and design) from Swann. I have the Swann ones next to the Rialco units for redundancy. I'll update this review if necessary.

### ⭐ Rialco 84010 Flood Alarm: Not Loud Enough
*by B***U on May 21, 2008*

I returned the Rialco 84010 Flood Alarm because it was not loud enough to be useful. I received a phone call from James J. Boyle IV, President of Operations, Quality e Companies, which shipped the alarm. Mr. Boyle said he would be sending me a check for $5.22 to cover postage I had incurred with my order. I was not satisfied with the alarm, but I was with the reply I received from Mr. Boyle.
