Live dispatcher available nowHow to know it's time
Most water heaters last 8–12 years. In El Cajon, hard water shortens that lifespan unless the unit's been regularly flushed. Signs it's time to replace, not repair:
-
!
Rusty or discolored hot water
Usually means the tank's interior is corroding from the inside out.
-
!
Pooling water around the base
A leaking tank can't be repaired — only replaced.
-
!
Loud rumbling or popping
Sediment buildup is overheating the tank — a sign of late-stage failure.
-
!
Over 10 years old & unreliable
Repair costs start to outweigh replacement once a unit ages out.
-
!
Hot water runs out way too fast
Could be a failing dip tube or end-of-life heating element.
