Frequently Asked Questions About Water Heater Repair in Onset, MA

This unpleasant odor happens when bacteria in your water react with the magnesium anode rod inside the tank. We can resolve this in Onset, MA by flushing the tank and replacing the standard rod with an aluminum-zinc or powered anode rod.
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.
An anode rod is a crucial component that attracts corrosive elements in the water. It rusts so your steel tank doesn't have to. You should have it checked every few years and replaced before it completely dissolves.
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.
Low hot water pressure is usually caused by scale buildup inside the water heater's pipes, or a faulty shut-off valve. If cold water pressure is fine, the issue is isolated to the hot water system and our technicians can clear the blockage.
