What Wichita hard water does to your water heater
Wichita draws hard water, and hard water is the single biggest factor in how long a water heater lasts here. Calcium and magnesium precipitate out when water is heated, settle as scale in the bottom of the tank, and form an insulating layer between the burner and the water above it. The heater works harder, runs longer and fails sooner.
The audible sign is rumbling or popping from the tank. That is water trapped under the scale layer flashing to steam and forcing its way up through it. A heater that rumbles is telling you it has a sediment problem, and it is worth acting on before the tank fails rather than after.
Flushing the tank annually removes loose sediment and genuinely extends life. It is a small job and most people never do it. Anode rods are the other maintenance item nobody checks: they are sacrificial and they corrode instead of the tank, and once one is spent the tank starts corroding from the inside out.
A water softener addresses the cause rather than the symptom, and in Wichita it pays for itself across the water heater, the fixtures and the appliances. Softened water also stops the scale buildup that clogs aerators and shower heads.
