Your water heater is essential for daily activities like showering, washing dishes, and laundry. Regular maintenance keeps it running efficiently, extends its lifespan, and helps prevent costly breakdowns. But how often should you schedule professional maintenance?

At Swift Plumbing & Heating, we help homeowners in Bainbridge Island, WA, keep their water heaters in peak condition with expert maintenance services.

Recommended Water Heater Maintenance Schedule

Annual Professional Inspection

To ensure optimal performance, schedule a professional water heater inspection once a year. A trained technician can detect potential issues early, preventing major repairs and unexpected breakdowns.

Tank Flushing Every 6 to 12 Months

Over time, sediment buildup in your water heater tank can reduce efficiency and increase energy costs. Flushing the tank every 6 to 12 months removes sediment and helps maintain consistent heating performance.

Anode Rod Inspection Every 2 to 3 Years

The anode rod prevents rust and corrosion inside the tank. Checking and replacing it every 2 to 3 years helps extend your water heater’s lifespan and prevents leaks.

Checking the Pressure Relief Valve Annually

The temperature and pressure relief (T&P) valve is a critical safety component. Testing it once a year ensures it functions correctly, preventing excessive pressure buildup that could damage your system.

Benefits of Regular Water Heater Maintenance

Regular maintenance provides several key benefits:

  • Improved energy efficiency – A well-maintained water heater heats water faster and uses less energy.
  • Extended lifespan – Routine maintenance can add years to your water heater’s life.
  • Fewer repairs – Catching small issues early prevents costly breakdowns.
  • Better water quality – Regular flushing removes sediment and minerals that can affect water taste and clarity.

Signs Your Water Heater Needs Immediate Service

If you notice any of the following issues, schedule a professional inspection as soon as possible:

  • Inconsistent water temperature
  • Strange noises coming from the tank
  • Rust-colored or foul-smelling water
  • Water leaks around the heater
  • Higher-than-usual energy bills
