Our hot water heater is four years old and defintely due for a draining which I intend to handle tomorrow. However. I discovered a calcium deposit at the copper valve controlling cold water entering the heater. I thought that calcium buildup would come after the heater, not before. DIYer that I am, don't know what to conclude. Is the well water so calcium intense that it may be the cause? Either way, I'll drain the heater. Any thoughts appreciated!
