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.
