My sons took their showers on yesterday (one after the other). After my last son's shower, he complained that the shower water turned cold on him. Afterwhich, I checked the water faucets, and none of them were running hot water. And the funny thing is when I turned the water on in my bathroom it started running in my tub as if I had turned the tub water on; although it was still only cold water. So, there is no hot water running out of any of the faucets in the house. Please help!
In order to help you I need to know what type of heater you have
