    Water Leak Detector

    $30 of sensors prevents $20,000 of damage.

    Why this matters most for travel

    A burst hose on a washing machine releases 600 gallons/hour. While you\'re away for a week, a small leak can flood every floor of the house. Insurance covers it but the disruption is months. Detection devices alert you — auto-shutoff systems STOP it.

    Best budget pick. Place under sinks, behind toilets.
