Trusted Water Heater Repair Specialists in Yosemite Valley, California

If you smell rotten egg sulfur odors from a gas leak, evacuate your home immediately. Do not flip electrical switches or use phones indoors. Once outside in fresh air, call your local gas utility and emergency services.

If your water heater is under 10 years old and the problem involves a replaceable component—such as a heating element, thermostat, thermocouple, or relief valve—repair is usually cost-effective. However, if the internal tank has rusted through and is leaking from the base, replacement is necessary.

The T&P relief valve opens to release excess pressure or heat. Leaking can indicate excessive municipal water pressure (above 80 PSI), thermal expansion from a closed plumbing loop, or a defective valve seat that needs replacement.

The anode rod is a magnesium or aluminum core inside the tank that attracts corrosive minerals, sacrificing itself to prevent the steel tank from rusting. It should be inspected every 2 to 3 years and replaced when more than 50% depleted.

A sulfur odor is usually caused by anaerobic bacteria in your water supply reacting with the tank's magnesium sacrificial anode rod. Our technicians in Yosemite Valley, CA can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
