Frequently Asked Questions

Traditional tank water heaters typically last 8–12 years, while tankless water heaters can last 20 years or more with proper maintenance.

Loud noises are usually caused by sediment buildup at the bottom of the tank. Flushing the tank annually can prevent this. Popping or rumbling sounds are the most common signs.

We recommend annual servicing for tank water heaters and every 1–2 years for tankless units. In hard water areas like most of California, more frequent servicing may be needed.

Sizing depends on your household size and usage. A general guide: 1–2 people need 30–40 gallons, 3–4 people need 40–50 gallons, and 5+ people need 50–80 gallons. We offer free assessments to help you choose.

If your unit is under 8 years old and the repair cost is less than 50% of a new unit, repair is usually the better choice. Older units or those with recurring issues are generally better replaced.

Tankless heaters provide endless hot water on demand, are 30–40% more energy efficient, last 20+ years, and take up significantly less space than traditional tank units.

This is usually caused by sediment buildup reducing tank capacity, a failing heating element, or a unit that's too small for your household's demand.

No — leaks are never normal and should be addressed immediately. Small leaks from the pressure relief valve may be minor, but leaks from the tank itself usually mean the unit needs replacement.
