Location: Tenn/Ala. | Check your water heater bypass valves. There are several variations over the years so I cannot tell you what they should look like, but they generally are fairly clear to show water in and out, with one running in between. This is the one that "bypasses" the heater and if it is open, and it will draw cold water around the heater rather than through it. |
