Common Gas & Electric Water Heater Repairs

Water Heater Repairs
Reading Time: 3 minutes

The water heater in your home might be one of the most underrated appliances, but of course, it plays an essential role in a smooth-running household. Water heaters generally have an extensive lifespan, if they are taken care of and receive regular maintenance and checks when required. Water heaters are mostly sturdy and reliable but since they are constantly being used, it is possible that problems may emerge. While some problems may be taken care of with water heater repairs, others may require a full replacement.

Problems That Occur with Electric Water Heaters

There are a few common concerns that homeowners find when it comes to the functioning of water heaters which may simply relate to general wear and tear, or lack of regular maintenance.

  • Insufficient Hot Water

    If your shower turns cold after only a short time in the shower this may be related to the temperature settings or if you have an electric heater, the heating elements may be faulty. There may also be sediment in the tank or faults with the dip tube. If your water heater isn’t producing any hot water, this may be a result of the gas control valve or the thermostat.

  • Bad Smelling Water

    If you have discolored water or a rotten egg smell when you turn on your water there might be a case of pipe corrosion or bacteria that has built up in the tank.

  • Strange Noises

    Rumbling noises or popping sounds when the water is boiling might be an indication of a buildup of sediment which results in overheating and the water boiling excessively. Hissing sounds may be an indication of leaks that are dripping onto the burner.

  • Water Leaks

    Faulty temperature or pressure relief valves may cause a leak in the water heater.

Flushing your water heater tank will reduce the amount of buildup of sediment which affects the amount of hot water in the tank and decreases the amount of hot water available for use. Regular water heater maintenance will increase the lifespan of your water heater and ensure that it works efficient.

Problems with Gas Water Heaters

If your home uses a gas heater and you have a lack of hot water, this might be because of an obstruction or shortage in the main gas valve. If the problem seems to be with your pilot flame, there might be an issue with the thermocouple.

  • Poor Airflow

    This will show signs of bad-smelling, burnt gas, a pilot outage, yellow burner flames, or a sooting burner flame. You’ll need to have the flue vent checked as well as the base of the water heater for any obstructions. The flame arrestor will need to be checked regularly too in order to prevent poor airflow.

  • Sooting

    This can occur because of a buildup of debris and dirt in the orifice or in gas supply tubing. If the gas chamber and the flue vents are sooted but the rest of the burner is clean there might be an incorrect orifice being used, excessive gas pressure, or there is a loose connection.

  • Condensation

    Condensation can occur because of the demand between an excessive amount of hot water used in a short space of time while the water is still cold. When water is heating, gases sometimes cool to dew point which causes condensation to travel back to the chamber which will affect the flame. Too much condensation can kill the flame that heats the water.

  • Pilot Light

    If the gas won’t stay lit, there might be an issue with the gas supply. This will result in low gas pressure and the pilot won’t stay lit. The pilot light can be affected by condensation, the combustion air supply, or a clogged vent system. Wiring and insulation faults around the igniter wire can also prevent the pilot light from igniting.

When it comes to repairing water heaters, both gas and electric heaters can be a dangerous task to undertake yourself. Our advice is to call a professional for any faults that may be affecting the efficiency of your water heating. These common issues can be easily repaired when they’re caught before they become a costly and dangerous inconvenience for your household.
