Frequently Asked Questions About Water Heater Repair in Northwest Harbor, NY

When water heats up, it expands by about 2% to 3%. In homes with a backflow preventer or check valve, this expansion creates severe pressure spikes. A thermal expansion tank absorbs this pressure, preventing leaks and protecting your warranty.
A pilot light that won't stay lit is usually caused by a faulty or carbon-coated thermocouple, a blocked pilot orifice, a defective gas valve magnet, or poor combustion air intake. Call (877) 276-9926 to have a technician test and replace the thermocouple safely.
If rust appears only in your hot water (not cold), the internal steel tank or sacrificial anode rod is corroding. If caught early, replacing the anode rod can save the tank; if the tank interior itself has rusted through, replacement is required.
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.
Yes! Installing a dedicated recirculating pump or a thermal bypass valve system keeps hot water constantly moving through your pipes, delivering instant hot water to your furthest shower and saving thousands of gallons of wasted water.
