Most water heater leaks do not arrive out of nowhere. They send warnings for months — a weeping valve, crusty fittings, a TPR pipe that drips now and then. A simple maintenance routine catches those warnings while they are still small. In hard-water country, this routine matters more, not less.
The once-a-year flush
Sediment is the slow killer: it piles up on the tank bottom, insulates the water from the burner or elements, overheats the steel, and accelerates corrosion. Flushing once a year clears the loose stuff out. One caveat for older, never-flushed heaters in mineral-heavy water: the drain valve may be crusted solid or brittle. Let a technician handle the first flush on an old unit — snapping a drain valve turns maintenance into a repair.
Test the TPR valve
Once or twice a year, lift the TPR valve’s test lever briefly and let it snap back. You should get a burst of water out the discharge pipe, then it should seal shut again. No water, or a valve that keeps dribbling afterward — that valve needs replacement. Never cap or plug the discharge pipe; it is the tank’s safety release.
Check the anode rod
The rod sacrifices itself so the tank does not have to, and in hard water it depletes faster — roughly 3–5 years is typical. If your heater is past that age and the rod has never been inspected, put it on the list. A fresh rod is the highest-value maintenance a tank heater gets.
Look at the pan, fittings, and shutoff
Every few months, take a sixty-second look: any moisture in the drain pan, crust on the top fittings, dampness around the drain valve? And try the shutoff valve — if it will not turn easily now, it will not turn during a leak either. Catching a weep early is a valve replacement; catching it late is water damage.
The desert schedule
Soft-water regions can stretch maintenance intervals. Apache Junction is not a soft-water region. Annual flushing, annual TPR tests, and anode checks on schedule are not overkill here — they are what gets a tank to the long end of its 8–20 year life instead of the short end. Want it handled?
