Water Alarm

[Richard Beels <beels@technologist.com>]

I know I've seen those little water alarms in some catalog.  You know the 
ones, stick the sensor on the floor and the cord runs to the buzzer that 
runs on a AA battery.  Cost $10-$15 or something like that.  After a near 
flooding of the basement by the whole house water filter unit deciding to 
die on me, I think a coupe of these would be a good idea.  :-)

Problem is, I can't remember where I saw them and I can't find them at Home 
Depot, Lowe's, MSC, MMC, Ace, etc...


Cheers!
