Frequently Asked Questions About Water Heater Installation in Union, WA

A healthy gas flame should burn a crisp, clean blue. A lazy yellow flame indicates incomplete combustion, dirty burner air shutters, or carbon monoxide hazard. Have Expert Water Heater Pros inspect the burner assembly immediately.
Scheduling is fast and easy. Call our direct field dispatch hotline at (877) 552-4213. Our local coordinators in Union, WA will log your symptoms and dispatch the nearest available technician to your property immediately.
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 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) 552-4213 to have a technician test and replace the thermocouple safely.
A cold water sandwich happens when hot water left in the pipes is followed by a brief surge of unheated water while the flow sensor triggers the burner. Installing an internal or external recirculating buffer tank eliminates this issue completely.
