Frequently Asked Questions About Water Heater Repair in Warrenville, IL
Low hot water pressure is typically caused by heavy mineral scale clogging the water heater's hot outlet nipple, a partially closed shut-off valve, or a defective heat trap. Our technicians can clean or replace the fittings to restore full flow.
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.
Direct vent units vent combustion gases naturally through a vertical chimney or B-vent flue. Power vent units use an electric fan motor to push exhaust horizontally through PVC or polypropylene pipes out a sidewall.
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.
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.
