From Cold Showers to Hot Baths: Troubleshooting Water Heater Issues

Have you ever been rudely interrupted during your morning routine by a sudden blast of cold water in the shower? Or perhaps you’ve eagerly anticipated a relaxing soak in a hot bath, only to find that the water is lukewarm at best? If you’ve experienced these scenarios, you’re not alone. Water heater issues can be frustrating and inconvenient, but fear not – Gilbert Plumbing is here to help you navigate through the maze of potential problems and solutions.

Signs of Water Heater Problems

Before diving into the specifics of troubleshooting, it’s important to recognize the signs of water heater issues. These can include:

  • Inconsistent Water Temperature: Fluctuations between hot and cold water can signal a problem with your water heater.
  • Unusual Noises: If your water heater is making banging, popping, or hissing sounds, there might be an underlying issue.
  • Leaks: Any signs of water pooling around the base of your water heater should be investigated promptly.
  • Rusty Water: Discolored water coming from your taps might indicate rust accumulation in your water heater.

Common Water Heater Issues

No Hot Water

If you’re only getting cold water from your taps, there might be a problem with the heating element, thermostat, or power supply. Check the thermostat settings and ensure the circuit breaker hasn’t tripped.

Inadequate Hot Water

When the amount of hot water isn’t meeting your needs, it could be due to sediment buildup in the tank or an issue with the thermostat. Flushing the tank or adjusting the thermostat settings might help.

Water Too Hot

Water that’s too hot can be a scalding hazard. This could be due to a faulty thermostat or a malfunctioning pressure relief valve. Make sure your thermostat isn’t set too high and that the pressure relief valve is working correctly.

Strange Noises

Banging or popping noises can indicate sediment buildup in the tank, while hissing sounds might be a sign of a leaking pressure relief valve. Flushing the tank can help eliminate sediment issues.


Water pooling around your water heater could be the result of a leak. Check for leaks in the tank itself, the pressure relief valve, and the plumbing connections.

Troubleshooting Steps

Check the Thermostat

Ensure that the thermostat is set to the desired temperature. If it’s too low or too high, it can affect the water temperature.

Inspect the Pilot Light

For gas water heaters, make sure the pilot light is lit. If it’s out, follow the manufacturer’s instructions to relight it safely.

Flush the Tank

Flushing the tank periodically can help remove sediment buildup, improving efficiency and water quality.

Insulate the Tank

Insulating your water heater tank can help retain heat and improve energy efficiency.

Check for Leaks

Inspect the tank and all connections for leaks. If you find any, they should be addressed promptly.
