Water Heater Maintenance Tasks

To make sure everything in your water heating system stays in good condition, you should do all these tasks. Don’t wait until you have water heater problems before you start taking care of it.


Most modern water heaters have internal insulation for optimal water heater safety. But, you should also add an insulation blanket on the outside. This helps the energy efficiency of the heater and saves you money on your bills!


About once a month, inspect the heater from bottom to top looking for leaks or corrosion. If you see any, take care of the problem ASAP!

Annual Flush

Over time, corrosive minerals in your water accumulate on the bottom into a gross sludge that can eat right through the bottom of the tank! That’s why it’s important to flush your tank once a year and get that gunk out.

Anode Replacement

The anodes of your heater attract corrosive chemicals so your tank doesn’t degrade. But those rods will erode over time. You’ll need to replace them every 4 years.

Tips for Maintaining a Water Heater

Many new homeowners like to take tips from the pros so they don’t make rookie mistakes. These are our favorite heater maintenance tips to get you started.

Install flood sensors near the heater in case it starts to leak. That way, you know if the unit leaks before it becomes a huge flooding issue.
