You can flush your water heater tank yourself (it’s easy). Or you can call Water Heater Pros and schedule a service technician to do it for you.
Here’s how to flush a water heater
1.) Purchase a “Flush Kit” at the time of your new water heater is installed by Water Heater Pros, we will install a brass full port flush valve, replacing the factory valve, ours have full 3/4″ port opening verses conventional 1/2″ factory port.
2.) Get a garden hose long enough to reach a drain lower than the bottom of the water heaters drain valve or reach outside, be careful not to drain in shrubs, grass, trees as the water is very hot and can kill these plants.
3.) Next, attach the garden hose to the flush valve located at the bottom of your water heater and extend the hose to discharge the water as mentioned above.
4.) Now simply open the flush/drain valve by turning the valve handle counter clockwise (left turn), some newer water heaters now have a screw driver slot, turn same counter clockwise direction until you hear water flowing. Let the water flow under pressure for five (5) minutes ONLY, do not shut off any other valves, gas or electric.
5.) Now you are done, shut off the valve clockwise (right turn) detach the garden hose and put away for next time.
Note: Don’t be confused, you are NOT draining the water out of the tank, you are flushing the tank. By flushing the tank, water is being discharged under pressure, stirring up the accumulated minerals at the bottom of the tank and discharging that debris through the garden hose and out of the water heater.
