Signs Your Water Heater Needs Repair
Changes in Water Temperature
Sediment buildup inside your water heater can insulate the heating element, causing fluctuating water temperatures or odd noises. Phoenix’s water supply has high mineral content that can cause sediment to build up faster, so you may need regular flushes and maintenance to prevent problems.
Water Discoloration
Rusty or brownish water is often caused by sediment buildup or corrosion inside your water heater. Phoenix’s desert water supply can have high mineral content, which causes corrosion and scale buildup. If you notice discolored water, contact Goettl immediately for an evaluation to ensure your water supply is safe for your family.
Lack of Hot Water
If your water supply is depleting faster than usual, it could be due to a malfunctioning heating element or faulty gas components like the gas control valve, thermocouple, or dip tube. Phoenix’s hot climate can also increase household water usage, making these issues more noticeable. Goettl can help you identify and resolve the issue to restore your home’s hot water supply quickly.
Strange Noises Like Banging, Popping, or Rumbling
If your water heater is making loud banging, popping, or rumbling noises, it could be caused by steam bubbles in the mineral deposits that create popping noises, failing heating elements, or underground water leaks, which sound like running water when your water heater isn’t in use.
A malfunctioning pressure relief valve or thermal expansion can cause humming or whining sounds, which need to be addressed as soon as possible. Otherwise, pressure can build inside your water heater, which may cause a massive leak or explosion.
Leaks or Bursts
Leaks can be caused by corrosion from age or minimal maintenance, loose plumbing connections, a failing pressure relief valve, or other causes. Addressing leaks quickly with expert repairs is important to prevent high water bills, costly water damage, and potential health hazards from mold or mildew growth.
Thermostat Issues
Your water heater’s thermostat regulates temperatures and ensures a steady hot water supply. If you’re experiencing inconsistent water temperatures or cold water, the thermostat may be failing. Our technicians can recalibrate or replace it to restore it’s function.
Pilot Light Issues
A pilot light that doesn’t light or won’t stay lit can be caused by issues with your gas supply, venting blockages, or a malfunctioning thermocouple. This affects your water heater’s function, so it’s important to call for an inspection and repair as soon as possible and make sure your water heater is safe and functional.
Gas Control Valve Malfunction
The gas control valve is responsible for regulating the flow of gas that runs to your water heater’s burner. If it fails, you can have no hot water or fluctuating water temperatures in your shower or sink. Our skilled plumbers can repair or replace faulty gas control valves to keep your water heater running as it should.
