Water Heater Repair in SeaTac, WA
When your home or rental property loses hot water, experiences tank leaks, or suffers from faulty heating elements and pilot failures, Washington Plumbing delivers prompt diagnostic troubleshooting and precision repair. Serving SeaTac homeowners, apartment complexes near Angle Lake, and properties along International Boulevard.
Comprehensive Water Heater Repair for SeaTac Homes
SeaTac homes range from mid-century ramblers in McMicken Heights and Riverton Heights to lakeside condominiums near Angle Lake. Our plumbers arrive equipped to diagnose gas control valves, electric thermostats, burned elements, and dangerous pressure relief failures.
Thermocouple & Pilot Assembly
Pilot lights that refuse to stay lit often suffer from defective thermocouples, clogged pilot orifices, or failed gas control valves. In older homes along Des Moines Memorial Drive, drafty utility closets can extinguish pilots.
We test gas pressures, clean burner assemblies, and replace thermocouples and electronic igniters with factory-approved components.
Call (253) 201-3775 →Heating Element & Thermostat Repair
If your water runs lukewarm or turns ice cold after two minutes, an upper or lower electric heating element has burned out. Sediment accumulation at the bottom of the tank accelerates element burnout.
We perform electrical resistance testing on upper and lower thermostats and replace high-draw copper or incoloy elements on the spot.
Call (253) 201-3775 →T&P Relief Valve & Leak Stops
Temperature and Pressure (T&P) relief valves are critical safety mechanisms that prevent tanks from over-pressurizing. Dripping valves indicate excessive pressure, thermal expansion failure, or seat corrosion.
We inspect thermal expansion tanks, replace weeping relief valves, and verify Washington state seismic strapping compliance.

Water Heater Repair vs. Replacement in SeaTac
Not every broken water heater needs to be replaced. Understanding the age, condition, and failure point of your unit helps you make a cost-effective decision.
When Is Repair the Right Choice?
If your storage tank water heater is under 8 to 10 years old and the steel vessel is not actively leaking, component repairs are typically fast and economical. Common repairable failures include:
- Faulty upper or lower dual thermostats on electric units
- Burned-out high-wattage heating elements
- Defective thermocouples, flame sensors, and pilot assemblies
- Weeping drain valves or faulty temperature-pressure relief valves
- Loose electrical wiring or faulty circuit breaker connections
If your unit has reached the end of its useful lifespan or the tank has rusted through, we also provide complete water heater replacement and modern energy-efficient tankless water heaters.
SeaTac Housing & Washington Code Factors
Many residences in SeaTac were constructed between 1955 and 1978 during airport expansion and regional aerospace growth. These homes frequently feature narrow utility alcoves, crawlspace water heater placements, or uninsulated garage installations.
Under Washington State Building Code (WAC 51-56), replacement or heavy repair of water heaters requires:
- Double earthquake seismic strapping anchored securely to wall framing
- Closed-system thermal expansion tanks where backflow check valves exist
- Full 3/4-inch copper or CPVC T&P discharge piping terminating near the floor or outdoors
- Sediment traps on gas supply lines before the gas control valve
Protect Your Home From Water Damage
If your water heater is showing signs of rust, weeping water, or knocking loudly, call us before catastrophic tank rupture occurs.
