The hard-water problem
Treasure Valley water carries a heavy load of dissolved calcium and magnesium. When that water is heated, the minerals drop out and settle on the bottom of the tank as sediment. On a gas heater, the burner then has to heat through a layer of rock before it reaches the water. The tank runs longer, the bottom overheats, and the steel fatigues. You’ll hear it first as a popping or rumbling sound, then notice the hot water running out sooner, then one day find a puddle.
The fix is twofold. Flushing the tank once a year removes the sediment before it hardens. Softening the incoming water keeps most of it from forming at all. We do the first on every service call and will tell you honestly whether the second is worth it for your household.
Choosing a replacement
Bigger isn’t automatically better. A tank sized too large for the house wastes gas keeping water hot that nobody uses; one sized too small means the last person showers cold. We size by the number of bathrooms, the people in the house and the peak-hour demand, then talk through fuel type, efficiency and whether a tankless unit makes more sense for your situation.
Every replacement we install includes a new expansion tank if the system needs one, correct venting, seismic strapping, a pan and drain where required, and the permit. The old unit leaves on our truck.
Repairs we make every week
No hot water on a gas heater is usually a thermocouple, igniter or gas control valve. On an electric heater it’s usually a heating element or thermostat, or a tripped high-limit switch that points to a deeper issue. Lukewarm water, slow recovery and strange noises are mostly sediment. A leak at a fitting is a quick fix; a leak from the tank body means it’s time. We’ll tell you which within the first few minutes.
