I’ve had 5 personal friends who have had enormous water leaks and full renovations in just the last year alone 🤯 WHY are these not standard for every home?! I purchased these a few months ago and totally forgot to place them throughout the house. Water is one of the leading causes of home damages. I need to buy another pack but immediately putting these out today. We’re placing them behind every toilet, under every sink, behind our washing machine, under our dog sink, under the dishwasher and behind all our refrigerators and even one next to our hot water heater, hvac unit and anywhere in the house where we don’t usually frequent. These work just like fire alarms. You put batteries in them and as soon as they detect water, they set off an alarm
