What to Expect from Our Water Heater Maintenance Service

Keeping your water heater in great shape is simple with our streamlined maintenance process:

  • Easy Scheduling: Give us a call and we’ll find a time that works with your schedule. We value your time—our team shows up promptly, ready to get to work.
  • Full System Inspection: Once we arrive, we perform a thorough check of your water heater’s key components, including thermostats and heating elements, pilot light or igniter (for gas units), temperature & pressure relief valve, and ventilation and insulation (if applicable). This helps us catch any early signs of wear or failure.
  • Flushing the Tank: Over time, sediment builds up inside the tank, which can reduce efficiency and shorten the unit’s lifespan. We flush the tank to improve heating performance, extend the life of your water heater, and reduce the risk of damage from mineral buildup.
  • Anode Rod Check & Replacement: The anode rod helps prevent rust inside your tank. If it’s worn down, we’ll replace it to protect your water heater from corrosion.
  • Professional Recommendations: If we spot any issues or signs of trouble, we’ll explain what we found, walk you through your options, and offer fast, effective solutions.

DIY Water Heater Maintenance to Make Your Water Heater Last Longer

Routine maintenance is key to extending the lifespan of your water heater. Here are some essential steps to keep it running efficiently:

  • Check and replace the anode rod to prevent rust and corrosion
  • Inspect the pressure relief valve to ensure it’s working properly
  • Set the thermostat to 120°F to avoid overheating and excessive wear

By following these steps, you can improve efficiency, reduce energy costs, and extend the life of your water heater—ensuring a reliable hot water supply for years to come.

Water Heater Maintenance FAQ’s

How often should I schedule water heater maintenance in Knoxville?

We recommend annual water heater maintenance for most Knoxville homes. If you have hard water or heavy usage, you might benefit from twice-yearly service to prevent sediment buildup and ensure optimal performance.

What does professional water heater maintenance include?

Our comprehensive maintenance service includes tank flushing, anode rod inspection and replacement, thermostat calibration, safety valve testing, leak detection, and efficiency assessment. We also provide maintenance tips to help extend your unit’s lifespan.

Can regular maintenance prevent water heater breakdowns?

Yes, regular maintenance can prevent many common water heater problems by catching issues early, removing sediment that causes overheating, and ensuring all components work properly. This significantly reduces the likelihood of unexpected breakdowns.

How much does water heater maintenance cost in Knoxville?

Maintenance costs vary based on your water heater type and service needs. However, annual maintenance is much more affordable than emergency repairs or premature replacement. Contact The Plumbing Authority for specific pricing information.

What happens if I skip water heater maintenance?

Skipping maintenance can lead to reduced efficiency, higher energy bills, shorter lifespan, and increased risk of breakdowns. Sediment buildup can cause overheating and damage, while worn components may fail unexpectedly.

Should I maintain my tankless water heater differently?

Tankless water heaters require different maintenance than traditional tanks, including descaling to remove mineral buildup. Our Knoxville technicians are trained in both traditional and tankless water heater maintenance procedures.

Can I perform water heater maintenance myself?

While some basic maintenance like temperature adjustments can be done yourself, professional service ensures safety and thoroughness. Our trained technicians can spot potential problems that homeowners might miss and have the proper tools for safe maintenance.
