#1 Water Heater Repair Service in St George, UT

Common warning signs include rusty or discolored water, water pooling near the unit, rumbling or banging noises, inconsistent hot water, slow heating, and a unit that constantly runs out of hot water. If your water heater is 8–12 years old and showing these issues, it likely needs repair.

The average tank water heater lasts 8 to 12 years with proper maintenance. After this age, repairs become more frequent, and replacement may be the most cost-effective option. Tankless water heaters can last 15 to 20 years with professional care.

A faulty water heater can be hazardous. Risks include gas leaks (leading to fire or asphyxiation), electrical shock in electric units, scalding hot water leaks, and even explosions if the pressure relief valve fails. If you suspect a problem, shut off the unit and call Iron Mountain Plumbing immediately.

We repair gas, electric, tankless, and hybrid water heaters. Our licensed plumbers have the training and equipment to diagnose and fix issues with all major brands and models.

Routine maintenance is key. We recommend flushing your tank at least once a year to remove sediment buildup, checking the anode rod to prevent corrosion, and scheduling regular professional inspections. Preventative care extends your water heater’s lifespan and keeps it running efficiently.

These noises are usually caused by sediment buildup at the bottom of the tank. As the sediment hardens, it traps water beneath it, creating loud pops or rumbles when the water is heated. Flushing the tank can often resolve this issue.
