Hi guys,
My wife and I bought our first house a few months back. Over the last month or two, I have noticed the hot water flow or pressure is getting less and less. This is noticed all over the house and not just in a sink or shower etc. The cold water flow is satisfactory.

I have recently flushed the hot water heater , it only seemed to have a little color to the water briefly. It didn't help the problem. We have city water. The house is 1890 with an electric hot water heater and copper pipes.

Thank you for any help you can give me on what next to do.

David
