You need to switch the power to your water heater and turn off the cold water inlet. Afterward, place a bucket of water under the valve and pull the lever. Usually, it produces some water vapor plus a rush of air. If the water continues flowing out of the valve, you must drain the tank partially. Next, unscrew the old valve and replace it with a new one.
Replacing the Anode Rod
Water heaters are usually designed with an anode rod. The anode rod protects the exposed steel of your appliance when the tank gets filled through electrolysis. The rod protects your water heater from rust. Therefore, there’s a high likelihood that it could become coated with calcium carbonate. If this happens, you should call water heater Dubai experts to carry out the necessary replacement.
