EMERGENCY PLUMBING KNOWLEDGE HUB FINANCING HELP & SUPPORT

Regular tankless water heater maintenance is crucial to ensure it runs efficiently and lasts longer. Over time, mineral deposits can build up inside the system, especially in areas with hard water like Arlington Heights, Illinois. Flushing your tankless water heater is a simple but important task that removes these deposits and keeps your water heater functioning optimally. Here’s a step-by-step guide to flushing your tankless water heater safely.


Step 1: Gather the Necessary Tools and Materials

Before you begin, make sure you have the following tools and materials on hand:


Arlington Heights Consideration:

Arlington Heights is known for having moderately hard water, which means more frequent maintenance may be needed to prevent mineral buildup. Regular flushing can help homeowners avoid the problems associated with sediment accumulation.


Step 2: Turn Off the Power and Water Supply

To ensure your safety, start by turning off the power to the water heater. If it’s electric, switch off the breaker, or turn off the gas supply if it’s gas-powered. Then, shut off the cold water supply valve to prevent new water from entering the system during the flush.


How This Helps:

Turning off the water and power supply prevents accidents and ensures the heater won’t be damaged during maintenance.


Step 3: Connect the Hoses

Your tankless water heater has two service ports for flushing—one for cold water intake and one for hot water output. Connect one end of a hose to the cold water service port and the other end to a pump. Place the pump inside a bucket filled with white vinegar or a specialized water heater cleaning solution. Connect the second hose to the hot water service port, and place the other end into the bucket to create a closed-loop system.


Step 4: Run the Pump

Turn on the pump and let it circulate the cleaning solution through the water heater for about 45 minutes to 1 hour. This process will break down any mineral deposits and flush them out of the system.


How This Helps:

Running the cleaning solution through the heater ensures that all the internal parts are descaled and any blockages from hard water minerals are removed.


Step 5: Rinse the System

After the pump has run for the designated time, disconnect the hoses and dispose of the used cleaning solution. Next, reconnect the cold water intake hose and flush the system with clean water for 5-10 minutes to rinse out any remaining vinegar or cleaning solution.


Step 6: Reconnect the Water Heater

Once you’ve finished rinsing the system, close the service valves, remove the hoses, and reconnect the water lines to their normal configuration. Turn the water and power supply back on, and your tankless water heater should be back to running efficiently.


How This Helps:

Rinsing the system ensures no cleaning solution remains inside, preventing any damage or lingering odors. Reconnecting the water heater properly is crucial to restore normal operation.


Conclusion

Flushing your tankless water heater regularly is a vital part of proper water heater maintenance. For Arlington Heights homeowners, performing this task every 12 months (or more frequently in areas with hard water) can prevent costly repairs and extend the life of your system. If you’re not comfortable doing this yourself or if you encounter any issues, don’t hesitate to contact a plumber in Arlington Heights for professional water heater maintenance.
