5 Tell-Tale Signs Your Water Heater Needs Repair in Reno
Your water heater works quietly behind the scenes to deliver hot water on demand. But when something goes wrong, it can quickly disrupt your home comfort. In Reno’s unique climate, water heater issues may arise more frequently due to hard water, winter freezing, or aging systems.
In this detailed guide, the experts at Reno Plumbing Doctor reveal the five most common signs that your water heater needs repair—and what you can do to fix them.
1. Fluctuating or Inadequate Hot Water Supply
Intermittent Hot Water
If your water turns cold unexpectedly during a shower or fluctuates in temperature, it’s likely your water heater is struggling to maintain a consistent supply.
Causes:
- Failing heating elements (electric models)
- Sediment buildup around burner (gas models)
- Malfunctioning thermostat
Inconsistent hot water is a common sign your unit is nearing the end of its service life or in need of immediate repair.

2. Discolored or Rusty Water
Signs of Internal Tank Corrosion
When rusty water flows from your hot water tap, it’s a red flag. The anode rod inside your heater may have corroded, or the tank lining itself may be failing.
Check for:
- Orange or brown tint in hot water
- Metallic taste or smell
- Rust flakes in your faucet screens
This issue is especially prevalent in older homes in Reno with galvanized plumbing.

3. Leaks or Water Pooling Around the Unit
The Silent Damager
Even a small leak around the base of your heater can lead to thousands in water damage.
Possible causes include:
- Cracked internal tank
- Faulty temperature and pressure relief (TPR) valve
- Corroded pipe fittings or flex hoses
Leakage is always a critical issue and should be addressed immediately.

4. Unusual Noises Coming From the Tank
Banging, Rumbling, or Popping Sounds
As sediment builds up at the bottom of your tank, it can harden and cause loud noises when the unit is heating water.
Long-term effects include:
- Reduced energy efficiency
- Overheating of the tank
- Stress fractures leading to leaks
Reno’s mineral-rich water supply accelerates this process, so regular flushing is essential.

5. Higher Than Normal Energy Bills
Water Heater Working Overtime
If your utility bills have spiked without a clear reason, your water heater might be losing efficiency.
Contributing factors:
- Sediment insulating the heating elements
- Thermostat set too high
- Continuous water leaks
Inefficiencies add up quickly and are one of the clearest financial indicators that a repair (or replacement) is overdue.
Reno-Specific Causes of Water Heater Damage
Hard Water Buildup
Hard water minerals can significantly reduce the life of your tank. Over time, this leads to scale formation, reducing heating efficiency.
Winter Weather & Frozen Pipes
During freezing temps, improperly insulated pipes can burst, and heater efficiency drops. Make sure your system is winterized properly.
