I've tried looking for an answer, but can't seem to find it anywhere and I'm hoping someone here can help. The cold water is hotter than my hot water. The weather here has climbed up to 115 degrees and I believe the problem is at the main line and it being burried too shallow. Seems like its a common problem with people I have talked to in my area. Since my hot water is actually just a tad bit better than what I'm getting from the cold tap I figured I would just shut off the water heater. Question is.. If I shut the power to the water heater (electric water heater) can I leave the cold line coming in at top on the on position and still use the water thats stored in the heater? I'm thinking I can get luke warm water that way instead of almost scalding hot water that I get from the cold tap. Also save some money on running it when I don't need it. Will this damage the water heater? Thank you.
