You’re in your bathroom, ready for a nice, hot shower after a long day. You turn the faucet, and… weird noises. Or maybe the water coming out is brown. Or worse, there’s a puddle by your water heater. You might be thinking, “What’s going on? Is my water heater about to break?” We get it. It’s frustrating and a little scary when something goes wrong with a big appliance like your water heater. It’s not just about losing hot water; it’s about the potential for expensive repairs and possible water damage. You’re a homeowner and you want things to work. You don’t have time for plumbing headaches.
At Instant Plumbing and Rooter, we’ve been helping folks in Glendale, Phoenix, Scottsdale and all over the Valley since 2001. We’re not a big, faceless company. We’re your neighbors, just really good at fixing plumbing. And we know water heaters. So, let’s talk about the signs your water heater might be giving you, and what they mean.
1. Strange Noises: Popping, Rumbling, or Cracking From Your Water Heater
What Causes These Noises?
Imagine you have a pot on the stove and it’s filled with sand. As it heats up, the sand shifts and makes noises. That’s kind of what happens in your water heater. Sediment, like sand or minerals, builds up at the bottom of the tank. As the water heats, it tries to get through the sediment, causing those weird noises.
The Potential Problems They Indicate
These noises aren’t just annoying; they are a sign your water heater is working harder than it should. The sediment reduces efficiency, meaning it takes more energy to heat the water. This can shorten the life of your water heater and make your energy bills go up.
When to Call a Plumber
If you hear these noises consistently, it’s time to call us. We can flush the tank, which means getting rid of the sediment. It’s a job best left to professionals, because you’re dealing with water and gas or electricity.
2. Discolored Water: Brown, Rusty or Cloudy Water From Your Faucets
What Discolored Water Means
Brown or rusty water usually means there’s rust inside your tank. This rust can come from the tank itself or from the pipes. Cloudy water might mean there’s sediment or air in the water.
Health and Appliance Risks
Rusty water isn’t good for drinking, and it can stain your clothes and fixtures. Sediment can also damage your appliances.
How to Flush Your Water Heater
You can try flushing your water heater yourself, but it’s tricky. You need to turn off the gas or electricity, drain the tank, and then flush it with clean water. If you’re not comfortable with this, call us.
3. Leaks Around the Water Heater Tank: Puddles and Dampness
Where Leaks Typically Occur
Leaks can happen at the top, bottom or sides of the tank. Top leaks usually mean loose connections. Bottom leaks can mean the tank is rusting through.
The Dangers of Untreated Leaks
Water damage is a big deal. It can ruin your floors, walls and belongings. Plus, leaks can lead to mold, which is a health hazard.
DIY vs. Professional Leak Repair
Small leaks might be fixable with a wrench and new gasket. But if the tank itself is leaking, it’s time for a new water heater. We can help you pick the right one.
4. Inconsistent Water Temperature: Lukewarm or No Hot Water at All
Common Causes of Temperature Fluctuations
This can be caused by a faulty thermostat, a broken heating element (in electric water heaters), or a problem with the gas valve or burner assembly (in gas water heaters).
Energy Efficiency Impact
If your water heater isn’t heating water properly, it’s wasting energy. This means higher utility bills.
When Replacement Might Be Necessary
If your water heater is old, it might be more cost-effective to replace it than to keep fixing it. We can help you figure that out.
5. Increased Utility Bills: Unexplained Spikes in Your Monthly Costs
How Water Heater Inefficiency Raises Bills
A water heater that’s working harder because of sediment or leaks uses more energy.
Comparing Energy-Efficient Models
Newer water heaters are much more efficient. We can show you some models that will save you money in the long run.
Long-Term Cost Savings
Investing in a new, efficient water heater can pay for itself in energy savings.

Extending Your Water Heater’s Life: Preventative Measures and Regular Maintenance
The Importance of Annual Water Heater Maintenance
Flushing the tank once a year gets rid of sediment and helps your water heater last longer.
Checking the Anode Rod
The anode rod protects your tank from rusting. It should be checked every few years.
Checking the Heating Elements or Burner Assembly
In Arizona, where we often deal with hard water, heating elements (for electric water heaters) and burner assemblies (for gas water heaters) can accumulate mineral deposits and sediment. This buildup reduces efficiency and can lead to premature failure.
- For Electric Water Heaters: We recommend checking the heating elements for signs of scale buildup or damage. If they’re heavily coated, they may need cleaning or replacement.
- For Gas Water Heaters: The burner assembly should be inspected for proper flame and cleanliness. Dust and debris can affect its efficiency and safety.
Regular inspection and cleaning of these components can ensure your water heater operates efficiently and safely, saving you money on energy bills and extending its lifespan.
