Anchor by Panasonic Water Tank Overflow Alarm Bell

<p>Overhead tanks overflow silently for 20 minutes while nobody notices — wasted water, a soaked terrace and seepage into the walls. This ₹345 sensor bell sits at the tank mouth and shouts a loud human-voice announcement plus buzzer the second water touches the top, so you cut the motor immediately.</p><p>It is slept-on because most people assume you need a full ₹4,000+ automatic water-level controller; this does the one job that actually matters for a fraction of the price and installs in minutes with no wiring changes.</p><p>Rated 4.2 stars across 1,535 Amazon.in ratings, from a mainstream Indian electrical brand rather than a no-name seller.</p>
