1-Turn Off Water Supply
If you have a gas heater turn the thermostat to the “pilot” setting, if your heater is electric turn off the power at the breaker box. Connect a hose to the drain valve located close to the thermostat, but do not open the valve yet. Turn off the cold water supply that feeds the water heater.
2-Drain the Hot Water
In order to prevent a vacuum from forming in the water line, go inside your home and open up one of the hot water faucets in one of your sinks or tubs. Go back to the water heater and open up the drain valve to drain hot water out of the tank. Make sure the other end of the hose is draining in a safe location, an outside driveway would be ideal.
3-Flush Out Remaining Sediment
Once the water stops flowing out of the far end of the hose turn the water supply back on. This will flush out any remaining sediment left behind in the heater. Once the water runs clear from the end of the hose close the drain valve. Dont forget to turn the hot water faucet inside your house back off.
Every water heater tank is different and you should always read the warnings and instructions in order to prevent damage.
4-Test the Pressure Release Valve
After the tank has filled with water turn the power supply back on at the breaker box or thermostat. Once the water temp has been brought back up, test the pressure relief valve per manufacturers instructions. This valve is designed to prevent overheating and excess pressure build up inside the tank. If it is faulty contact City Wide Plumbing to have it replaced.
