FAQs

What are the most common signs of water heater problems?

Look for inconsistent water temperatures, strange noises like popping or rumbling, leaks around the base, or rusty/smelly water. These are typical warning signs that something’s not right.

How long should I wait before investigating a water heater issue?

Don’t wait at all! Even minor issues can quickly escalate into major problems. As soon as you notice anything unusual, it’s worth checking out to prevent potential damage or complete failure.

What's the difference between electric and gas water heater problems?

Electric heaters often have element or thermostat issues, while gas heaters typically face pilot light or thermocouple problems. However, both types can experience sediment buildup, leaks, and tank corrosion.

When is it time to replace rather than repair?

Consider replacement if your unit is over 10 years old, repairs are becoming frequent, or there’s significant tank corrosion. Sometimes, a new, efficient unit is more cost-effective than ongoing repairs.

Can regular maintenance prevent most water heater problems?

Absolutely! Annual maintenance, including tank flushing, anode rod checks, and pressure relief valve testing, can prevent up to 80% of common water heater issues and extend your unit’s life significantly.
