I have removed the anode rod from an electric water heater and it is coated with a crystal and chalk like substance and there is a lot of this crud in the bottom of the tank. I have replaced this water heater, but would like to use it in another location. 1. Should this anode rod be replaced? 2. Is there any way to clean the bottom of the tank? (other than flushing)
If the cylinder is older than 5 years then Rheem recommend that the anode be replaced to enable it to carry on protecting the cylinder from corrosion – be careful that you replace it with the correct one – which is usually identifable by the colour on the top of the anode screw in nut. As far as cleaning out the cylinder – flushing is by far the best and safest way to achieve the desired result. By using any product other than just water you carry the risk of damaging the connection pieces and the interior walls of the clinder. Hope this helps.
