Signs Your Water Heater Needs Repair
Changing Water Temperatures
Sediment buildup inside your water heater may coat the heating element, leading to uneven water temperatures or strange noises. San Antonio’s water supply varies in mineral content, which can cause buildup much faster. Regular maintenance is the best way to prevent problems and extend the life of your water heater.
Water Discoloration
If your hot water heater has a reddish or brownish tint, it could be caused by corrosion inside the tank or mineral buildup. Over time, the city’s water conditions can lead to sediment accumulation that affects water clarity and taste. If you notice discoloration, call Goettl as soon as possible to ensure the water is safe for your family.
Lack of Hot Water
You count on your water heater for a steady flow of hot water. If the water is too cool, it could be caused by a faulty heating element, a failing thermocouple, a damaged gas control valve, or a broken dip tube. Given San Antonio’s hot summers and cold winters, homeowners often rely on more water – making the issue more noticeable. Our team can figure out the cause and get it fixed to get your hot water flowing again.
Strange Noises Like Banging, Popping, or Rumbling
Your water heater makes some noise during operation, but it shouldn’t be disruptive. If you hear banging, popping, or rumbling sounds, it could be caused by wear and tear on components or faulty heating elements or steam bubbles caused by mineral buildup. Underground leaks also cause noises, particularly the sound of running water when you have no fixtures in use.
If you hear a whining or humming sound, it could be caused by a failing pressure relief valve and pressure buildup that could cause an explosion or leak. Call Goettl for emergency repair immediately if you suspect a pressure relief valve problem.
Leaks or Bursts
A water heater leak can cause considerable water damage, high water bills, and health risks from mold and mildew, so it should be addressed quickly. There are many possible causes for leaks, including failing pressure relief valves, loose or faulty connections, or corrosion caused by age, hard water, or minimal water heater maintenance.
Thermostat Issues
Your water heater’s thermostat controls the temperature and ensures a steady hot water supply. If you have fluctuating temperatures or no hot water, a faulty thermostat may be to blame. Our experts can inspect and recalibrate or replace your thermostat to restore your system’s performance.
Pilot Light Issues
A pilot light that won’t ignite or can’t stay lit can have a lot of causes, including a failing thermocouple, issues with the gas supply, or a venting issue. Our technicians can determine the cause and perform necessary repairs to ensure your water heater operates safely.
Gas Control Valve Malfunction
The gas control valve regulates fuel flow to your water heater’s burner. A malfunctioning valve can cause inconsistent heating or no water at all. If your water temperature fluctuates or you have no hot water, our team can inspect, repair, or replace your gas control valve.
