When this becomes an emergency

What a pro does

A plumber's first job on a water heater call is deciding whether it's a repair or a replacement, and that's usually settled in the first ten minutes. Water coming from the tank body itself means the steel has corroded through, and no part fixes that. Water at a fitting, the relief valve or the drain valve is often repairable. From there the diagnosis follows the fuel. Gas units get the thermocouple, the gas control and the flue checked, and the draft matters in Omaha basements where a heater shares a chimney with an older furnace. Electric units get elements and thermostats tested. The local complication is mineral content. Hard water leaves scale on the tank floor and on the elements, so a heater here works against a growing insulating layer for its whole life. A plumber will drain some of the tank and read what comes out, since heavy sediment explains rumbling, slow recovery and a burner that runs long. Expansion also gets a look, because a closed system with no expansion tank pushes the relief valve open every heating cycle.

Frequently asked questions

Water trapped under a layer of sediment flashing to steam as the burner fires beneath it. It's a scale symptom, and it means the burner is heating a mineral crust before it heats your water.
It slows sediment buildup if it's done regularly from early in the tank's life. On a heater that's gone a decade untouched in hard water, a flush sometimes disturbs the layer and reveals corrosion that was already there, which is worth knowing rather than a reason to skip it.
Either the valve has failed or the pressure in the system is genuinely rising. On a house with a check valve or a meter setup that stops water flowing back toward the street, heating expansion has nowhere to go, and the relief valve becomes the only outlet.
That depends on your policy and on whether the damage came from a sudden failure or a slow leak nobody caught. Your insurance provider is the only one who can tell you how yours reads, so call them before the old tank gets hauled away.
