Ok today I'm posting about a cheap gadget that I think everyone should have.
It's a battery-powered water/flood leak detector.

I have two of these guys, one in the bathroom and one under the kitchen sink.
You put them on the floor and if water ever gets underneath them they let out the most piercing beeps.
Now if you're lucky you'll never have one of these guys go off on you because of a real problem, and only because you accidentally spill some water.
But they provide me with significant peace of mind when i fill up the tub, etc., that if something goes wrong I will at least have a change at being alerted to it before it's too late.
The brand I use is Zircon:

first alert ones also look good and are possibly easier to change batteries on).
