Why Older San Jose Homes Experience More Water Heater Issues

Many San Jose homes were built before 1980. Aging plumbing systems can place added strain on water heaters, and sediment buildup is often more common in older water lines. Past installations may also be improperly sized for today’s household usage.

Inspection helps identify root causes early so you can avoid damage, disruption, and repeat failures.

Signs You May Need Water Heater Service

No hot water or rapidly cooling water

Often caused by issues with the burner, heating element, thermostat, or sediment buildup inside the tank.

Water is pooling around the heater

May indicate internal tank failure or fitting leaks.

Rusty or discolored hot water

Common with aging tanks or corroded connections.

Popping or rumbling noises

Typically caused by sediment buildup inside the tank.

Sudden increase in utility bills

Reduced efficiency or system malfunction can increase costs.
