Frequently Asked Questions About Water Heater Repair in Castle Rock, WA

A gas burner should have a crisp blue flame. A yellow or orange flame indicates that the burner is not getting enough oxygen for complete combustion, which can produce dangerous carbon monoxide. It needs immediate cleaning and adjustment.
Hard water is very tough on tankless heaters because the intense heat causes calcium to rapidly build up inside the narrow heat exchanger. You must have your tankless unit descaled annually to prevent irreversible damage.
A hybrid heat pump water heater uses electricity to pull heat from the surrounding air and transfer it to the water in the tank. This makes them highly energy-efficient, often saving homeowners significantly on their monthly utility bills.
That rumbling or popping sound is caused by a thick layer of mineral sediment at the bottom of your tank. Water gets trapped under the sediment and boils, creating steam bubbles. A professional flush by Water Heater Repair Tech can clear this out and quiet the tank down.
If your home is on a closed plumbing system (such as having a pressure reducing valve), thermal expansion can cause dangerous pressure spikes when water heats up. An expansion tank absorbs this pressure and protects your water heater.
