Common Questions About Water Heater Repair in Mendon, IL

A pilot light that won't stay lit is typically caused by a dirty or defective thermocouple, a clogged pilot tube orifice, or a faulty gas control valve. Call (877) 652-1357 to have our certified technician test the millivolt output and fix the ignition safely.
Traditional storage tank water heaters generally last between 8 and 12 years with routine annual maintenance. Tankless systems can last 20 years or longer when properly descaled and serviced regularly.
Water dripping from the T&P valve typically indicates excessive pressure in your plumbing system, thermal expansion issues, or a worn-out valve spring. We can test your water pressure and install an expansion tank or new safety valve as needed.
