Answers:    Does you hot hose down seem hotter than it should be? Check the nouns valve on the top of your hot hose tank. Could be especially dangerous!!!!!! When hose down turns to steam, its volume expands by 1700 times. If your HWT blew up, your home would look like a tornado hit it. Don't fool beside this.
