Frequently Asked Questions About Water Heater Installation in Ontario, OR

The anode rod is a magnesium or aluminum core inside the tank that attracts corrosive minerals, sacrificing itself to prevent the steel tank from rusting. It should be inspected every 2 to 3 years and replaced when more than 50% depleted.
A hissing sound in gas heaters often occurs when condensation drips onto the hot burner assembly. Whistling usually indicates restricted water flow through a valve or excessive internal pressure escaping past a safety seal.
We service all leading manufacturers including Rheem, Bradford White, A.O. Smith, Rinnai, Navien, State, Lochinvar, Bosch, and Kenmore. Our field vehicles carry factory OEM parts for both storage tanks and tankless systems. Contact us at (877) 552-4213.
