Frequently Asked Questions About Water Heater Installation in Dennis, OK

Condensation is common when a cold tank is filled with water during initial startup. However, continuous dripping beneath the tank after hours of heating indicates an internal tank leak requiring immediate inspection.
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.
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.
If your water heater is under 10 years old and the problem involves a replaceable component—such as a heating element, thermostat, thermocouple, or relief valve—repair is usually cost-effective. However, if the internal tank has rusted through and is leaking from the base, replacement is necessary.
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.
