A water heater leaking from the tank is an emergency, the tank is failing and needs immediate attention. We respond 24/7 across Seattle and King County for water heater emergencies.
Repair or Replace?
How to Decide
Not every water heater problem requires replacement. Here's how we think about it:
Repair makes sense when:
-
The unit is less than 8 years old
-
The problem is a specific component: thermostat, heating element, pilot light, valve
-
The tank itself shows no signs of corrosion or leaking
Replacement makes sense when:
-
The unit is 10+ years old
-
The tank is leaking or visibly corroded
-
Repair costs exceed 50% of replacement cost
-
The unit is undersized for your household's current needs
-
You want to upgrade to a more efficient tankless system
We give you an honest assessment before any work begins, repair when it makes sense, and replace when it doesn't.
Plumbing System Maintenance | Questions Homeowners Ask
The earliest warning signs are inconsistent water temperature, water that runs hot then suddenly cold, and a longer wait time for hot water than usual. Other early signs include popping or rumbling sounds from the tank, which indicate sediment buildup, and slightly discolored or rusty water at the hot tap. Catching these signs early often means a repair rather than a full replacement.
Traditional tank water heaters typically last 8 to 12 years with proper maintenance. Tankless water heaters last significantly longer, 15 to 20 years on average. In King County, water quality and sediment levels affect lifespan; units that are flushed annually consistently outlast those that aren't. If your water heater is approaching 10 years old and showing any symptoms, it's worth having it inspected.
The clearest signs are age combined with symptoms. A unit over 10 years old that is making noise, producing rusty water, or failing to maintain temperature is likely near the end of its life. A tank that is actively leaking from the body, not from a fitting or valve, needs immediate replacement. The tank itself cannot be repaired once it begins leaking.
It depends on what's failing. If the tank is in good condition and the problem is a specific component, a thermostat, heating element, or pressure relief valve, repair often makes sense even at 10 years. If the tank shows corrosion, is leaking, or has had multiple issues, replacement is the better investment. We assess this honestly before recommending either option.
Once a year, for most homes in Seattle and King County. Sediment from the water supply accumulates at the bottom of the tank, reducing efficiency and accelerating corrosion. Annual flushing removes this buildup and can add years to your unit's life. Tankless water heaters require annual descaling rather than flushing; the process is different but equally important.
The most common factors are lack of maintenance, particularly skipping annual flushes, high water pressure, which stresses the tank and components over time, a depleted anode rod that is never replaced, and water with high mineral content that accelerates sediment buildup. In King County homes, having your water heater serviced annually addresses all of these factors and consistently extends unit lifespan.
