A water heater is a simple appliance but one that can make taking a shower miserable when it is broken. Here is how to fix a water heater or at least how I did it.
There are only a few things that can go wrong with a water heater. If the tank itself is leaking, it’s time to get a new one. But if your water heater is leak free but just not heating your water, it can be fixed.
My pilot light kept going out and the hot water didn’t seem to last very long anymore so I thought I would replace the thermocouple. The thermocouple is a device made from different types of metals that react to heat. When it is heated it sends an electrical single to the gas control valve to inform it of the presence and temperature of the flame. Thermocouples are easy to replace. I just unscrewed the old one along with pilot tube, burner and igniter from the control valve and replaced. The older style water heaters had a single thermocouple that could be replaced on its own. These newer style water heaters have a combination of thermocouple, pilot tube and igniter all together.
