How to Troubleshoot Your Water Heater

Lacking hot water is no fun. And discolored, smelly water is just as bad. What to do?

Difficulty:

Moderately Easy

Instructions

Things You'll Need

• Chlorine
• Garden Hoses And Attachments
• Thermometers
• Flashlights

1. Make sure the breaker hasn't tripped, if you have an electric unit and are not getting any hot water. Press the reset button on the thermostat inside the access panel if a tripped breaker isn't the problem.

2. Suspect a buildup of sediments in the water-heater tank if the hot water is discolored or is taking a long time to replenish. If this is the case, you'll need to drain the tank completely and flush it with clean water.

3. Check the water heater's temperature settings if you have noisy plumbing. It might be too hot, and the noise may be the result of steam building up in the pipes.

4. Make sure you aren't running multiple appliances that use hot water - running the dishwasher and the washing machine will make your shower short and not so sweet.

5. Notice whether the water smells like sulfur. Sometimes bacteria that live in the water get out of control. A good dose of chlorine will usually take care of the problem. (Consult your owner's manual for the recommended dosage.)

6. Check the water temperature when the tank is full. Run hot water from the tap over a thermometer. It should be within 5 degrees of the thermostat setting. Replace the thermostat if there is a larger discrepancy.
