These codes and their parameters are in place because a failure to properly install and repair plumbing structures can result in serious damage — not only to the home itself, but potentially even to other homes nearby, to city property, or the local environment.

Frequently Asked Questions

Do you have questions about our water heater repair and replacement services? Check out our compiled commonly asked questions or give us a call.

  • Not every water heater issue requires replacement. Here are a few of the most frequent problems with water heaters that can be resolved through repairs:

    1. Sediment Buildup: Over time, minerals and sediment can accumulate at the bottom of the water heater tank, reducing its efficiency. Draining and flushing the tank can help remove the buildup and restore optimal performance.
    2. Pilot Light Problems: If your water heater's pilot light keeps going out, it may indicate a faulty thermocouple. Replacing this small heat sensor is usually enough to fix the problem.
    3. Minor Leaks: A leaking water heater can indicate a significant problem. For minor leaks, checking and tightening the connections, such as the temperature and pressure relief valve, may resolve the issue.
    4. No Hot Water: It can be frustrating when you turn on the tap and only get cold water. In most cases, a faulty heating element is to blame. Replacing the malfunctioning element can restore hot water to your household.
    5. Inadequate Hot Water Volume: If your water heater does not provide enough hot water to meet your needs, the thermostat or the heating element may be the issue. Adjusting the thermostat or replacing the defective component can often fix it.
    6. Pressure Relief Valve Discharge: An overly active pressure relief valve can indicate high water pressure. Installing a pressure regulator or reducing valve can help regulate the pressure and prevent potential damage to the water heater.
    7. Gas Control Valve Issues: If you have a gas-powered water heater and experience issues with the control valve, such as a constant gas smell or difficulty igniting the pilot light, it is crucial to seek professional assistance. Gas-related repairs should only be handled by qualified professionals to ensure safety.
