Total loss of water is stressful, but a few quick checks — done safely — can sometimes fix the problem outright, and will almost always help us diagnose faster once we arrive.
Well pumps typically run on a dedicated circuit. A tripped breaker is the single most common cause of a sudden, total loss of water, and it's the easiest thing to rule out. If your pump control setup runs through a GFCI outlet, check that too — GFCIs trip more easily than standard breakers and are often overlooked.
If there's a pressure gauge near your pressure tank, check the reading. Zero pressure with the pump silent suggests an electrical issue or a genuinely failed pump. Pressure present at the gauge but no water at the faucets points toward a plumbing issue downstream rather than the well system itself.
A humming sound with no water movement can mean a seized motor, a failed capacitor, or a control box problem — useful to mention when you call, since it helps us bring the right parts.
Power surges are a common cause of sudden control box or pressure switch failure. If a storm rolled through recently, mention it — it changes what we check first.
If there's still some pressure in the system, hold off on running multiple fixtures at once until we've assessed the situation, so you're not draining what reserve exists in the pressure tank before help arrives.
