Frequently Asked Questions About Water Heater Repair in St. Helena, CA
You can improve efficiency by insulating hot water pipes, installing an external fiberglass tank blanket (on electric models), flushing sediment, and setting the thermostat to a safe, efficient 120°F (49°C).
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.
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.
