Frequently Asked Questions About Water Heater Repair in Contoocook, NH

Most conventional tank water heaters last between 8 and 12 years, depending on local water hardness and routine maintenance. Tankless systems can last 20 years or more with regular annual descaling.
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 Contoocook, NH can sanitize the tank and install an aluminum-zinc or powered titanium anode rod to neutralize the smell permanently.
Fluctuating shower temperatures can result from mineral buildup restricting water heater flow, a failing pressure-balancing shower valve cartridge, or simultaneous hot water usage exceeding system capacity.
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.
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.
