Step 7 · Restore Power and Final Cleanup

Once you have double-checked that there are absolutely no leaks and the water heater tank is full (indicated by a steady flow from the hot water taps), you can safely restore power. Go back to the electrical panel and flip the water heater's circuit breaker back to the 'ON' position. The water heater will now begin to heat the water in the tank. Tidy up your tools, wipe up any spilled water, and dispose of the old expansion tank according to your local recycling or waste disposal regulations, as it is considered scrap metal.
