Frequently Asked Questions About Water Heater Installation in Petersburg, IL

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.
The T&P relief valve opens to release excess pressure or heat. Leaking can indicate excessive municipal water pressure (above 80 PSI), thermal expansion from a closed plumbing loop, or a defective valve seat that needs replacement.
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.
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.
In electric water heaters, lukewarm water usually means the upper element is functioning but the lower element has burned out. In gas units, it often indicates a damaged dip tube or a miscalibrated thermostat control.

"Our water heater started making loud popping and rumbling noises like a kettle about to burst. The technician from Expert Water Heater Pros flushed pounds of mineral sediment out of the tank and inspected the anode rod. Now it runs whisper quiet!"
