So, I bought a house approx. 6 months ago and finally decided it was time to drain the hot water heater. It is a Richmond unit that obviously is not original to the house. I drain it and did not see very much sediment come out of the drain hose and turned the water valve on to refill it. Now, when I turn a sink on anywhere in the house, I rusty colored water. Will this eventually run out? Or how should I go about getting rid of it without having to buy a new water heater? Thanks for your help
