What maintenance should be done on a hot water tank?

Proper water heater maintenance is essential to ensure your hot water tank runs efficiently, extends its lifespan, and prevents unexpected breakdowns. Whether you have a traditional tank or tankless system, routine upkeep is key to maintaining steady water temperatures and energy efficiency. Here's a guide on the most important maintenance tasks that will help you keep your water heater in top shape, especially if you own water heaters in North Vancouver.


1. Check the Temperature Settings


One of the simplest and most effective maintenance tasks is adjusting the thermostat. It's recommended to keep your hot water heater set to around 120°F (49°C). This prevents scalding risks and saves energy, reducing utility bills. Regularly checking the temperature ensures it hasn't accidentally been altered.


2. Inspect for Leaks


Leaks around the water heater can indicate serious problems. Regularly inspect the area around your tank for any signs of moisture or corrosion. If you spot rust or puddles, it may be time for a professional inspection. Catching leaks early can prevent water damage and extend the life of your heater.


3. Test the Pressure Relief Valve


The pressure relief valve helps prevent the tank from building up excessive pressure, which can cause the tank to burst. To check it, lift the valve's lever slightly and let it snap back. If water flows out when you do this, the valve is working correctly. If nothing happens, it may need to be replaced.


4. Drain the Tank to Remove Sediment Buildup


Sediment naturally accumulates at the bottom of the tank over time, especially in areas with hard water. This buildup can cause the heater to work harder, leading to inefficiency and premature failure. To avoid this, it's recommended to drain and flush the tank at least once a year. If you're unsure how to do this, a professional can assist.


5. Inspect the Anode Rod


The anode rod is a metal rod inside the water heater that prevents rust by attracting corrosive elements in the water. Over time, it becomes corroded and may need to be replaced. Checking the anode rod every two to three years can prevent rust from building up in your tank and extend the life of your water heater.


6. Check the Burner or Heating Element


If your water heater runs on gas, inspect the burner flame. A blue flame indicates it's working efficiently. If it’s yellow or orange, the burner may need cleaning. Electric water heaters, on the other hand, have heating elements that should be checked periodically for any signs of wear or malfunction.


7. Insulate the Tank and Pipes


Insulating your water heater can help reduce heat loss, improving efficiency. Adding insulation to the tank and exposed hot water pipes will ensure water stays hotter for longer periods, lowering energy costs. You can purchase pre-cut insulation jackets for your tank and foam pipe insulation for the pipes.


8. Schedule Annual Professional Inspections


While some maintenance tasks can be done yourself, it’s a good idea to have a professional inspect your water heater annually. A trained technician will check for potential issues you may overlook, such as gas leaks or electrical faults, ensuring your heater runs safely and efficiently.
