Common Questions About Water Heater Repair in Williamsville, 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.
We service and repair all major manufacturers, including Rheem, Bradford White, A.O. Smith, Rinnai, Navien, State, Lochinvar, Bosch, and Whirlpool. Our service trucks are stocked with OEM parts for both storage tank and tankless systems. Contact us at (877) 652-1357.
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.
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.
We recommend an annual sediment flush for conventional storage tanks in Williamsville, IL, especially in regions with hard municipal water. Tankless systems should also receive a descaling flush every 12 to 18 months.
