If the water coming out of your faucets does not seem to be as hot as it used to be, you may wonder if your hot water heater is on the brink of failing. If so, look for the following signs that it's time to replace your old water heater.
Hot Water Has a Strange Color
Along with the temperature of your water being cooler than it should be, one of the first signs that may alert you to a problem with your water heater is the color of your home's hot water. You may notice that it has a slightly brown or reddish tinge, indicating that sediment or metal is flaking off and contaminating your water.
However, discolored water could also be a sign of a broken pipe that is allowing dirt into the water supply. If you see the discoloration in both your hot and cold water, this may be the problem. If you see the color change in only your faucets' hot water, the likely culprit is your water heater.
Water Heater Is Noisy While Running
Another sign that your water heater is going bad is the presence of loud popping noises while it running. These sounds are created when the burner heats up the sediment in the water, causing it to release air
While a few pops are nothing to be particularly worried about, if your heater sounds as though you are popping popcorn inside of it, then there is probably more than a few deposits of sediment on the inside of the tank. There is a good chance that the tank is caked in sediment and rust which are eating through the interior of the tank.
Water Leaks from the Tank
As the rust and sediment break off into the water, so does part of the metal from the tank. The louder and more constant the popping noises that you hear, the greater the chance that your tank will soon start developing holes and cracks.
At first, you may only see increased condensation on the outer surface of the heater's tank. However, as the tank deteriorates, you may start finding puddles of water around your hot water heater.
If your old hot water heater is exhibiting any of the above signs, it is most likely getting ready to fail completely. Before that happens, contact a professional to discuss your options for replacing your old appliance with a new hot water heater that fits your household's needs.
