When this becomes an emergency

What a pro does

No hot water splits three ways almost immediately, and the plumber sorts it before touching anything. There's no heat being made, there's heat being made and lost, or the tank's failed outright. On an electric unit the usual finding is a burned-out lower element or a tripped high-limit, and a house that keeps tripping the limit is telling you something about sediment. Gas units point at the thermocouple, the gas valve, or a vent that isn't drawing. Water chemistry drives a lot of this in East Tennessee. The limestone under this part of the state hands the water heater a steady mineral load, whether it comes from a utility or from a well on a ridge lot, and that mineral settles into a layer on the tank floor that insulates the burner from the water it's supposed to heat. The tell is a rumble or a popping sound while it's running. When the tank's the problem rather than a part, the plumber checks the venting and the connections at the same time, since a replacement done properly means looking at what feeds it and what carries the exhaust away.

Frequently asked questions

More often it's sediment. A mineral layer on the bottom takes up volume the tank was designed to fill with water and slows heat transfer, so the usable amount of hot water shrinks even though the tank size never changed.
Water trapped under a mineral crust on the tank floor, flashing to steam and forcing its way out. It means the burner or lower element is fighting through a layer of scale, which is hard on the tank and on the energy bill.
It can. Well water on the ridges around Knoxville often carries more dissolved mineral and sometimes iron, and both accelerate what builds up inside a tank. Brown hot water with clear cold water usually means the trouble is inside the heater rather than in the supply.
Sometimes. A thermocouple or a single element on a tank with life left is a sensible fix. Once a tank is leaking from the body itself, there's nothing to repair, because the failure is the steel shell rather than a component bolted to it.
