Water Heater Repair in Montana

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.

This occurs when you turn off the hot water briefly and turn it back on. You get the hot water already in the pipe, followed by a brief burst of unheated water, then hot water again. Modern units or recirculation pumps can fix this.

Hissing usually happens when condensation from the tank drips down onto the hot burner beneath it. It can also happen if there is a tiny leak spraying onto a hot surface. Have a professional inspect it to be safe.

First, find the cold water valve above the heater and turn it clockwise to stop the water flow. Second, turn off the power (flip the breaker for electric, or turn the gas valve to 'off' for gas). Finally, call Water Heater Repair Tech at (877) 415-0636 for emergency service in Montana.

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.
