How to Know It’s Time to Replace Your Old Water Heater vs Repairing It
True Plumbing
September 25, 2025
Most of us don’t give our plumbing a second thought until something goes wrong. When your water heater stops working, it’s more than a small inconvenience—it can throw off your entire routine. Few things are more frustrating than turning on the tap and finding only cold water.
So what should you do when that happens? This guide is designed to help Vancouver, Washington homeowners recognize the warning signs and decide whether a quick water heater repair will do the job or if it’s time for a full water heater replacement.
Signs Your Water Heater Needs Attention
It’s not always obvious when a water heater is failing. Watch for these common signs of a failing water heater:
- Not enough hot water or no hot water at all
- Inconsistent water temperature—too hot or too cold
- A leaking water heater or visible moisture around the tank
- Rusty or discolored water coming from the taps
- Strange noises such as popping or rumbling
If you notice any of these, schedule an inspection right away. A professional plumber can pinpoint the problem before it causes more damage.
Determining the Right Time for Water Heater Replacement
Most standard tank-style water heaters are built to last about 8 to 12 years, while tankless models can often perform well for 15 to 20 years. The exact life span depends on your household’s water quality, daily usage, and how faithfully you’ve followed routine water heater maintenance tips. To check your unit’s age, look for the serial number on the manufacturer’s label. If the date is not clear, you may need to contact the manufacturer to decode it.
Once a water heater reaches the ten-year mark, even well-maintained systems typically start to lose efficiency. Repairs may become more frequent or less effective, and energy costs can begin to rise. Upgrading to a modern energy-efficient water heater ensures faster heating, reliable performance, and lower utility bills, making a full water heater replacement in Vancouver WA the smarter long-term investment.
Repair or Replace: Weighing the True Cost of Your Water Heater
Deciding whether to repair or replace a water heater is more than a simple price check. A minor fix such as a new thermostat or valve is usually worth it. But when service calls become frequent, the costs can climb close to the price of a new unit.
Replacing a water heater can seem like a major expense at first. However, today’s energy-efficient models typically lower monthly utility costs and may even qualify for local rebates. Over time, those savings can offset the initial price and deliver lasting value.
Look at the warranty before making a decision. Most manufacturers cover a unit for 6 to 12 years. If your heater is still under warranty, certain repairs can be far less expensive.
Comfort and performance matter too. A growing household that constantly runs out of hot water likely needs a larger tank or tankless water heater installation. A properly sized system keeps showers hot and energy costs lower.
Finally, consider the unit’s condition. Severe corrosion, a broken control valve, or significant leaks signal that replacement is the safer and more cost-effective choice. In those cases, repairs are usually only a short-term patch.
By weighing both the financial and practical factors, you can decide with confidence whether a focused water heater repair in Vancouver WA will suffice or if a full water heater replacement will deliver the best long-term value.
