Preventative Maintenance for Longevity
Regular maintenance, such as draining storage tanks to prevent sediment build-up, is key to extending the lifespan of your water heater. Our technicians are skilled in all aspects of water heater care. Auburn replacements require a permit—we handle that process end-to-end.
Water Heater Replacement in Auburn
When your water heater is 10+ years old, failing repeatedly, or no longer meeting your family’s hot water demands, replacement is often the smarter investment. Our Auburn technicians provide honest assessments and fast replacement with energy-efficient models.
When to Replace
Water heaters over 10–12 years old, showing rust-colored water, rumbling noises, or repeated pilot/burner failures are strong candidates for replacement rather than repair.
Tank vs. Tankless
We help Auburn homeowners choose between traditional tank water heaters (lower upfront cost) and tankless units (endless hot water, higher efficiency, PSE rebate-eligible).
Heat Pump Upgrades
Electric resistance water heater? Upgrade to a heat pump water heater and save 60–70% on water heating costs. PSE offers up to $850 in rebates for qualifying upgrades.
Same-Day Replacement
Most Auburn replacements are completed the same day you call. We stock Bradford White, Rheem, Navien, Noritz, and Rinnai units on our trucks for immediate installation.
Old Unit Removal
We handle complete removal and responsible disposal of your old water heater. No extra charge for haul-away — we take care of everything from disconnection to cleanup.
Permit & Inspection
All replacements are fully permitted through the Auburn Building Division. We submit permit applications, schedule inspections, and ensure your installation passes first time.
Water Heater Repair in Auburn
From no hot water emergencies to rumbling tanks and pilot light failures, Fast Water Heater Co. diagnoses and repairs all water heater issues in Auburn. We service all major brands including Bradford White, Rheem, Navien, Noritz, and Rinnai.
No Hot Water
If your water heater is producing no hot water, the cause could be a faulty thermostat, failed heating element, tripped breaker, or defective gas valve. We diagnose and fix the root cause.
Pilot Light & Ignition Issues
Gas water heater won’t stay lit? A dirty thermocouple, clogged pilot tube, or faulty gas valve are common culprits. Our Auburn technicians repair or replace these components same-day.
Sediment & Noise
Rumbling, popping, or kettling sounds indicate sediment buildup on the tank floor. We perform professional tank flush and descaling to restore efficiency and quiet operation.
Leaks & Pressure Issues
Leaks from the T&P valve, drain valve, or tank connections require immediate attention. We repair or replace faulty valves and connections to prevent water damage to your Auburn home.
Tankless Error Codes
Navien, Noritz, and Rinnai tankless units display error codes for scale buildup, ignition failure, and flow sensor issues. We’re factory-trained to diagnose and clear these codes.
Anode Rod Replacement
Anode rods protect tank liners from corrosion. We inspect and replace depleted anode rods during service calls, extending tank life by years and protecting your warranty.

Auburn Water Heater FAQs
Answers to the questions Auburn homeowners ask us most.
Don’t see yours? Call us at the number above or request service online.
How much does water heater installation cost in Auburn, WA?
Installation cost in Auburn depends on fuel type (gas, electric, or heat pump), tank size, venting requirements, and whether code upgrades are needed for permits. Standard 40–50 gallon replacements are our most common Auburn job and typically complete same-day. For an exact quote, call us or request service online — we give firm pricing before any work begins, and every quote includes removal of the old unit, code-compliant installation, and City of Auburn Permit Center filing.
Do you offer same-day water heater repair near me in Auburn?
Yes. Call by 12 PM and we’ll have a Washington-licensed technician at your Auburn address the same day in most cases. We carry common replacement parts (thermocouples, gas valves, heating elements, T&P valves, anode rods) on every truck so most Auburn-area repairs are completed in a single visit.
Is Fast Water Heater Co. licensed in Washington?
Yes — Fast Water Heater Co. is a fully licensed Washington contractor (WA L&I), bonded, and insured, serving Auburn and the Puget Sound region since 1986. Every installation is performed by Washington-licensed plumbers and pulled under the correct City of Auburn Permit Center permit.
What water heater brands do you install in Auburn?
We install and service Bradford White, Rheem, A. O. Smith, Rinnai, Navien, Noritz, and Stiebel Eltron tank, tankless, and heat pump water heaters throughout Auburn. Our most-requested Auburn installs are Bradford White 50-gallon gas tanks, Rinnai tankless units, and Rheem ProTerra heat pump water heaters — which qualify for Puget Sound Energy and Seattle City Light rebates.
Do I need a permit for water heater replacement in Auburn?
Yes. Washington State requires a plumbing permit for every water heater replacement, issued through the City of Auburn Permit Center for Auburn-area addresses. Our install price always includes pulling the permit, scheduling the inspection, and meeting the Washington State Plumbing Code — you don’t lift a finger. Skipping the permit risks fines and complicates home insurance claims, warranty coverage, and the resale of your home.
How long does a water heater installation take in Auburn?
Most standard tank-to-tank water heater replacements in Auburn take 2–4 hours from arrival to cleanup. Tankless and heat pump installations typically take 4–8 hours depending on venting runs, electrical upgrades, and condensate drainage. We schedule same-day whenever possible — call by noon and most Auburn homes have hot water back the same afternoon.
Do you service tankless water heaters in Auburn?
Yes. We install, flush, descale, and repair tankless water heaters throughout Auburn. Auburn homes from Lea Hill down to Lakeland Hills and out to West Hill — we handle tank, tankless, and heat pump installations across every corner of Auburn. Annual descaling protects the manufacturer warranty — most tankless units we service reach 20+ years with correct maintenance.
What areas of Auburn do you serve?
We serve every Auburn-area neighborhood, including Lakeland Hills, Lea Hill, West Hill, Downtown Auburn, North Auburn, Pacific, Algona, Auburn Valley, Plateau, Bridge Camp, Federal Way, Kent, and the surrounding communities throughout King County.
