Water Heater Repair Tips

Gas-powered water heaters can encounter problems related to the burner. Dirt or rust on the burner can prevent it from igniting properly. Also, blockages in the gas line can cause your water heater to lose heating power. For these issues, contact a water heater repair technician.


A leaking water heater is a nuisance, but fortunately, many quick fixes can resolve the issue. One easy way to repair a leak is to remove the drain valve from the bottom of the tank. This will allow you to drain the excess water from the tank. To repair the valve, you should first locate the leak.

The problem most likely lies with the cold water inlet or outlet of the water heater. You may also notice a puddle near the water heater. A leak can cause this in one of the pipes or by the condensation of nearby appliances. In any case, you should inspect the water heater’s base for leaks and the pressure relief valve.

Another cause of leakage is a loose fitting. If the fittings are loose, you should tighten them with a wrench. If you cannot tighten them, you can use Teflon tape. It can also be helpful to tighten the fittings by turning them anti-clockwise.

If you are repairing a water heater, a broken thermocouple is one of the most common problems. You can fix the problem yourself by using simple tools. First, disconnect the water heater’s burner assembly and gas supply tube. Then, it would be best to reconnect the thermocouple’s lid using an adjustable wrench. Once the new thermocouple is connected, light the water heater and test it.

The thermocouple is a safety instrument that determines when the water heater’s pilot is burning. A malfunctioning thermocouple can cause the pumping circuit to shut down and waste hot water resources. To check if the thermocouple is working properly, use a thermocouple tester. If the tester doesn’t work, you can try to relight it. The thermocouple is often located on the burner system, but you may not have to disassemble it.

After decades of use, the thermocouple can degrade. It may also be damaged by corrosion. To check if your thermocouple is working, press the pilot button and test the current with a multimeter set on millivolts. To test the current, connect the thermocouple tester to the gas valve and the copper sheath of the thermocouple. If the tester reads an amperage of about one millivolt, the thermocouple is functioning properly.

If your water heater is not functioning properly, you may try relighting the pilot light by following the manufacturer’s instructions. These instructions are usually found on the heater’s door panel or the heater itself. If you cannot find them, you may contact the manufacturer’s customer service for further instructions. You can also consult your owner’s manual for more information. Before relaying the pilot, you must ensure that the gas valve is turned off.

To make sure that the gas valve is shut off:

  1. Turn it off using the main shutoff valve.
  2. Make sure that there are no people or pets in the home, and open all windows.
  3. Never attempt to light the pilot light yourself. You can call a licensed plumber if you’re unsure what to do.

The steps for relighting the pilot light vary with each system, but ensuring your safety is important. Always remember to follow manufacturer instructions and always consult a professional plumber.

Water heaters typically have two thermostats: one on the top of the unit and one on the bottom. These thermostats regulate the temperature of the water in the tank and shut off the heating element when it reaches a specific temperature. A faulty thermostat may prevent the unit from shutting off when the water inside reaches a set temperature. If you are concerned about the temperature of the water in your water heater, resetting the thermostat may be the solution.

A faulty thermostat may also cause the reset button to trip repeatedly. This can also result in the heating element operating after the set temperature. A faulty heating element may also have a short that can allow power to pass through it, causing the water to continue heating. The reset button will eventually become worn, which will cause it to trip without notice, regardless of the temperature of the water.

Another possible cause for overheating the water is a faulty high-limit switch. This switch is located on the thermostat and has four terminals. The bottom two terminals are used for power transfer. If these two terminals do not have power, the water heater is not safe to operate. You should call a professional to check this part.
