Is Your Arlington Water Heater Going Bad? Here Are the First Signs to Watch For

Rusty or discolored water coming from your hot tap is one of the clearest signs your water heater is failing. It usually means the inside of your tank has started to corrode. Once corrosion sets in, it doesn't reverse — and a corroding tank is a tank that needs to be replaced.

Before you call, there's a quick test worth doing. Run your cold water tap for 30 seconds and check the color. This helps narrow down whether the problem is your water heater or your pipes.

Arlington homes built in the 1980s and 1990s are more likely to have older galvanized plumbing. Ruling that out first helps you get the right fix the first time.

If the cold water runs clear but your hot water is still discolored, the tank is the problem. At that point, repair is rarely the right call. Internal corrosion almost always means replacement is the smarter and safer move.

If your water heater is making noise, sediment is almost always the reason. North Texas has hard water — mineral levels the U.S. Geological Survey classifies as among the highest in the country. Over time, minerals settle at the bottom of your tank and harden. When that happens, your heating element has to work through that layer every single cycle.

The noise itself is annoying. What it signals is worse.

Here's what each sound typically means:

• Rumbling — sediment has built up and is shifting as water heats
• Popping or banging — hardened deposits are trapping water beneath them as it heats
• Hissing or whistling — for tankless units, this points to scale buildup inside the heat exchanger

Sediment buildup reduces efficiency and puts extra strain on your tank. Left alone, it accelerates wear and can lead to overheating or full tank failure. In some cases, a professional flush can help. In others — especially on units past the 10-year mark — the damage is already done and replacement is the better investment.

Arlington's hard water conditions make this a common issue. Our technicians see it regularly in homes across the area. If your unit is making noise and it's been more than a decade since installation, it's worth having it looked at before it stops working entirely.

Water near the base of your water heater is a sign you should never ignore. Even a small amount of moisture can mean something serious is developing inside the unit. The longer it sits, the worse it gets.

Not every leak means an immediate replacement. Here's how to read what you're seeing:

Water heaters operate under pressure. A small drip from the tank body can escalate quickly. What starts as a slow leak can become a significant release of water with little warning. That means damage to your floors, walls, and anything stored nearby.

Standing water also creates conditions for mold growth. In Arlington homes where water heaters are often located in garages or interior utility closets, a leak that goes unnoticed for even a few days can cause real structural damage.

If your showers are running cold faster than they used to, your water heater is telling you something. This is one of the most common signs Arlington homeowners notice — and one of the easiest to dismiss. Don't. A shrinking hot water supply almost always points to a real problem inside the unit.

Here are the four most common causes, starting with the most likely:

1. Sediment buildup — mineral deposits take up space inside the tank, leaving less room for hot water
2. Failed heating element — in electric units, one burned-out element cuts your available hot water significantly
3. Thermostat malfunction — water isn't reaching the set temperature, so it runs out faster
4. Undersized tank — if your household has grown, your current unit may no longer keep up with demand

Sediment is the most common culprit, and it connects directly to the noise issue covered earlier. If your unit is rumbling and you're also running out of hot water faster, those two signs together point to a system that is working harder than it should just to keep up.

Age matters here too. A 10-year-old unit showing reduced output is rarely worth repairing. A new, more efficient unit will perform better and last another decade.

If you recognized any of the signs in this guide, the right move is to call for an inspection. One sign is enough. You are not overreacting — these symptoms exist because something inside your unit is already under stress.

Here is what to do next:

1. Identify what you're seeing — rusty water, noise, a leak, or shorter hot water supply
2. Don't wait for it to get worse — water heater problems rarely resolve on their own
3. Call Baker Brothers for a same-day inspection — we'll tell you honestly whether you need a repair or a replacement
