How to Know If You Need Water Heater Repair or Full Replacement
When your water heater stops doing its job, the last thing you want is to waste time (and money) guessing whether a repair will fix the problem or if it’s time for a complete replacement. While some issues can be resolved quickly, others signal that your water heater is past its prime. In this guide, we’ll break down how to tell the difference and what steps to take.
TLDR: Repair vs. Replace — Know the Signs
If your water heater is under 8 years old and showing minor issues like lukewarm water or a small leak, repairs may be enough. But if it’s over 10 years old, rusted, leaking from the tank, or driving up your energy bills — replacement is likely the smarter (and more cost-effective) option.

How Long Do Water Heaters Last?
Most traditional tank water heaters last between 8 to 12 years. Tankless units may last up to 20 years with proper maintenance. If your system is nearing or past this range, it’s a major factor in deciding whether to repair or replace.
When to Consider Water Heater Repair
If you’re experiencing any of the following, a repair might be all you need:
- Inconsistent water temperatures: This could be due to a faulty thermostat or heating element.
- Low hot water pressure: Often related to sediment build-up or minor plumbing issues.
- Strange noises: Rumbling or popping could be caused by sediment inside the tank, which can often be flushed.
- Small leaks from fittings: These may just require tightening or replacing a valve — not a full replacement.
Repairs are typically fast and cost-effective when caught early. HOTCO Solano offers quick emergency repair services, 24/7.
When to Replace Your Water Heater
Replacement is usually the best route if you notice these issues:
- Corrosion or rust: Especially on the tank or in the water itself — this signals permanent damage.
- Tank leaks: If the tank itself is leaking, it’s non-repairable and must be replaced immediately to avoid flooding.
- Skyrocketing energy bills: Old or inefficient heaters often work harder and longer, wasting energy.
- Frequent breakdowns: If you’re calling for repairs multiple times a year, it’s time to invest in a new unit.
