There are essentially two possibilities as to why your home would run out of hot water. First, the dip tube could have broken off. The dip tube forces incoming water to the bottom of your tank so hot water will be drawn off from the top. When the dip tube breaks, cold water entering the tank mixes with the hot water and reduces the water temperature. This issue can occur with both gas and electric models.
Second, if your water heater is electric, the lower element that heats the water may not be operating properly, thus only the upper half of the tank will heat up. This can be caused by a bad element or a thermostat malfunction. This type of problem should be evaluated by a licensed Denver plumber.
Additionally, you may want to check if a toilet in your home is leaking. First, check the water level to ensure water is not overflowing the tank. To determine the water level, look for the overflow pipe, which should be located in the middle of the tank. It has small tubing connected to it. If water is running into the overflow, adjust the fill valve to stop the flow approximately one inch below the top of the overflow tube or to the water level mark stamped on the side of the tank.
Another method to try is to put a few drops of food coloring into the tank to check the flush valve mechanism. If the water in the bowl changes color within 15 minutes, this is an indication that water is leaking into the toilet bowl and the ball or flapper needs to be replaced
