It's funny, you learn something new everyday.
I was watching the food network cannel and they ask the question , which boils faster ,hot water or cold water.... well we all know it's hot w
ater .Then they said you should never cook with hot water because of all the bulls##t thats in your hot water heater...you know ...rust,heavy metals and so on and so on.(then the light bulb went off in my head) For years , when I did water changes , I used the sink so I could adjust the temp. of the water....THUS.... USEING water from my hot water heater. SO needless to say I was puting that bulls##t in my tank . So from now on
it's cold water only.
