Answer: "Clearly, the first thing to do if your hot water is too hot is turn down the temperature on the water heater’s thermostat dial. Note the present setting (or mark it with a felt-tip pen), and then turn it toward a cooler setting, wait a couple of hours, and see if the problem is solved. If steam or excessively hot water shoots out of faucets, or you hear boiling sounds inside the water heater, the appliance may not be shutting off at its set temperature. The job of the temperature-pressure (TP) relief valve is to release excessive pressure from steam buildup, but this valve may have been improperly installed, or it may be faulty. Either way, this condition can be dangerous, both because hot water and steam can scald people and because the water heater could rupture. Turn down the water heater’s temperature and allow the water to cool, then replace the water heater’s pressure relief valve. "
