Sediment buildup from Aurora’s mineral heavy water is one of the most common culprits behind water heater problems, from rumbling noises to reduced hot water capacity. Our plumbers check for sediment along with more mechanical issues like a failing thermostat or heating element.

If a repair is not going to be cost effective given the unit’s age, our water heater replacement team can provide a straight comparison of repair versus replacement costs. Gas fired units may also need attention from our gas line team if the issue traces back to supply pressure.

• Rumbling or popping noises: Almost always sediment buildup hardening at the bottom of the tank.
• Not enough hot water: Can point to a failing heating element or thermostat, or a tank that has become undersized for household needs.
• Water heater leaking: May be a fixable fitting or valve issue, or a sign the tank itself has failed.
• Pilot light won’t stay lit on gas units: Often a thermocouple issue rather than a full unit failure.

A few issues show up repeatedly in Aurora water heaters, largely tied to water hardness and elevation.

Should I repair or replace my Aurora water heater?

If the unit is under six years old and the issue is isolated to a single component, like a thermostat or heating element, repair is usually the more cost effective choice. Once a water heater passes the eight to ten year mark, especially with Aurora’s hard water accelerating internal wear, replacement often makes more financial sense than investing in a repair for a tank nearing the end of its expected life anyway.

Why does my water heater make rumbling noises?

Rumbling or popping sounds are almost always caused by sediment that has settled and hardened at the bottom of the tank, which is common in Aurora given the mineral content in local water. As water heats beneath that sediment layer, it creates the popping sound. A professional flush can often resolve this if caught before it causes more significant efficiency loss.

Can a water heater repair extend the unit’s life significantly?

Yes, addressing an isolated issue like a failing thermostat or sediment buildup can often add several years of reliable service to a water heater that would otherwise be at risk of premature failure, making repair a smart investment for units still within a reasonable age range.
