Why Your Water Heater Dies Faster in Hurricane & St. George

Water heater repair is one of the most common calls we run in Southern Utah, and the reason behind most of them is the same: hard water. If your water heater gave up sooner than you expected, there's a good chance minerals did it.

Here's what hard water does inside a tank, the signs that yours is struggling, how to stretch its life, and how to tell a real repair from a sales pitch.

What hard water does inside your tank

Much of the water in St. George, Hurricane and the surrounding area is hard, carrying dissolved calcium and magnesium. When your water heater heats it, some of those minerals come out of solution and settle to the bottom of the tank as sediment. Year after year, that layer builds.

• On a gas water heater, sediment sits between the burner and the water like insulation. The burner runs longer, the tank bottom runs hotter, and the steel wears out faster.
• On an electric water heater, the lower element sits in that sediment and gets crusted with scale until it overheats and burns out.

The warning signs

• Popping or rumbling. Water trapped under sediment boiling as the tank heats. The classic hard-water sound.
• Hot water runs out faster. Sediment takes up room that used to hold hot water.
• Slow recovery after showers or laundry.
• Rusty or cloudy hot water. Often a worn anode rod or corrosion inside the tank.
• Moisture at the base. Sometimes a fitting or drain valve (small fix), sometimes the tank itself (not).

How to make a tank last longer

1. Flush it once a year. Draining the sediment is the most effective thing you can do. We flush and inspect tanks as part of water heater service.
2. Check the anode rod. It corrodes so your tank doesn't, and hard water uses it up faster. Once it's gone, the tank starts rusting from the inside.
3. Test the T&P relief valve. It's a safety device. If it's stuck or dripping, have it checked.
4. Keep the temperature reasonable. Around 120°F is plenty for most homes, and hotter water drops more minerals out of solution.

Up in Cedar City there's one more item: in a hard freeze, a water heater in an unheated garage or crawlspace and its supply lines can be at risk. Insulating exposed pipes is cheap insurance.

Repair or replace?

Many water heater problems are inexpensive: a bad thermocouple or gas valve, a burned-out element or thermostat, a leaking drain valve. If that's what's wrong, that's what we fix, and some of those really are a $50 repair.

If the tank itself is leaking, it needs replacing. If it's older and on its third repair, we'll tell you honestly when another repair isn't worth it. Our techs are paid hourly, not on commission, so there's no reason for us to oversell you.

Tank vs. tankless in hard water

Tankless water heaters (we install Rinnai and Navien, among others) heat water on demand, so there's no running out mid-shower and no tank to rust through. They still need periodic descaling in hard water. Kept on schedule, a tankless unit typically lasts longer than a tank and takes up far less space.

We'll quote tank and tankless side by side, in writing, so you can compare.

Common questions

How long does a water heater last in St. George?

Hard water usually shortens tank life compared with soft-water areas. Flushing the tank every year and replacing a worn anode rod help a tank reach the long end of its lifespan.

Should I flush my water heater?

Yes. With Southern Utah's hard water, an annual flush is the single best thing you can do for a tank water heater.

Does a tankless water heater work with hard water?

Yes, but scale still builds up inside it, so a tankless unit needs periodic descaling. Done on schedule, tankless units typically outlast tank water heaters.
