Ever wonder how rooftop water tanks stop overflowing automatically? π° In this quick 3D breakdown, we look at the mechanics of a float valve (level control) and an air vent. As the water rises, the buoyant float lifts the lever to shut off the incoming water supply, while the air vent balances internal pressure to prevent vacuums and maintain smooth flow. Perfect for understanding residential plumbing essentials!
