There are several guides online that will teach you to fix water heater installed in your home. Once you sense a problem in your water heater, it does not necessarily mean that you will have to replace the whole item and scrap the old one. Sometimes, all you need to do is to thoroughly check and determine the root cause to easily solve the issue without spending too much. Here are quick solutions to some of the common water heater problems.
When hot water is not coming out, do not panic! Check the pilot light if you are using a gas water heater, if not then you may have to replace the thermocouple or the pilot control valve. If the water coming out of your faucet has a foul odor, a bacterial infection occurred within your tank. What you need to do now is to empty your tank and fill it with a hydrogen peroxide solution (3% for 2 pints of you have a 40 gallon water tank) and let it sit for at least 2 hours. If you see a brownish tone in your water, it is a sign that you need to change the anode rod.
