Makes sense. We have it for our electricity (or lack of right now), why not have it for our water and gas? Liquid Breaker makes a circuit breaker for your water (and gas). The Omni Breaker Panel monitors remote sensors that when tripped, turn off the water to the water circuit and sends an alert message via an email, text message, fax or all of the above. You can also access the Omni Breaker via any computer connected to the internet — perfect for turning off the hot water to an unsuspecting showerer. Pricing depends on how many circuits (zones) you want to protect.
