What’s Included in Water Heater Maintenance?

A hot water heater should be inspected 1-2 times each year. Here’s what that consists of:

  • TPR Valve Inspection

    Our technicians will inspect the temperature release valve to confirm it isn’t blocked or damaged. This valve allows water to drain if the pressure inside the tank gets too high.

  • Damage and Corrosion Inspection

    The anode rod is designed to intentionally attract debris, corroding itself rather than the water heater. We’ll examine it to see if this should be replaced.

  • Flushing & Cleaning

    Tank water heaters should be flushed a couple times a year to avoid the buildup of rust, corrosion, or sediment. Tankless water heaters should also be cleaned out regularly to ensure continued efficiency.

  • Clean Filters

    Tankless water heaters have filters that should be cleaned on a regular basis. These filters prevent sediment and excess buildup from getting into your water pipes.

  • Tank water heaters should be drained at least once a year. Technicians will also inspect internal components like the anode rod to determine if it needs to be replaced, as well as the temperature pressure release (TPR) valve to ensure it’s not blocked. The TPR valve releases water when there is excess pressure in the tank and ensures that your pipes don’t burst. If this valve isn’t functioning right, we can recommend if it needs to be replaced.

  • Although tankless water heaters don’t store water, the system still ought to be flushed from time to time. There are also two filters in tankless water heaters that stop buildup or debris from getting through, and our techs examine and clean those thoroughly.

  • Homeowners should schedule hot water heater maintenance 1-2 times per year, depending on the type of water heater, energy source and the community’s water quality. Tankless water heaters should have maintenance carried out twice per year.

Having routine maintenance for both tank and tankless water heaters can decrease the need for expensive repairs because things are less likely to break.
