If you have a gas water heater in your home, it is important to know simple troubleshooting steps so that you can do some of the repairs yourself. Troubleshooting is a simple process as it just involves you figuring out why the heater is not working, then performing the necessary fixes.
When you do the repairs yourself you can save on time as well as plumbing costs should a professional handle it on your behalf:
The most important tip when dealing with gas water heater repair is to ensure the gas is turned off whenever you are working on the system. This is because gas is explosive and should always be handled with care. The gas usually has a specific odor that you are most likely to be familiar with.
Should you smell that odor even after turning off the main controls, it might indicate that there is a leak in your system. In this case, you should not risk your life but you should call a professional instead to continue with the repairs.
Additionally, you should remember that you are dealing with hot water. This can scald you if you are not careful. You can either wait till the water cools down or do the repairs with care around the hot water reservoirs.
Water Does Not Heat
The main cause for your heater not working is usually the thermocouple. This is the part that controls the passage of gas from the tanks to the heaters and acts as a switch. It is connected to the pilot light that indicates whether the gas water heater is on or not. You can find this switch and light near the hot water reservoirs usually located somewhere in the basement.
When the light is on, the thermocouple allows gas to pass through. If the light is off, it means the thermocouple is restricting the passage of gas. If the light is on but there is still no hot water, it might mean that the thermocouple is faulty. In this case, you need to purchase a new one.
Inadequate Hot Water
Sometimes the gas water heater may be working, but only slightly. This means that you do not get enough hot water. The problem could be as a result of a faulty thermostat. The thermostat is installed along the gas valve and acts to automatically control the water temperatures.
When the water is hot enough, the thermostat automatically turns off the heating process. When the water cools down when the gas heater is still turned on, the thermostat turns the heaters on. Thus when it is faulty, it will not perform its duties properly. This means you should have it replaced with a new one.
