The warning signs
- Age. Check the rating plate; many tanks last ten to fifteen years.
- Rusty hot water. Brown water from hot taps only suggests tank corrosion.
- Rumbling or popping. Sediment buildup overheating at the bottom.
- Moisture at the base. Small leaks become large ones.
- Less hot water. Sediment or a failed element reduces capacity.
- Relief valve dripping. Excess pressure or temperature.
What to check
Read the serial number: many manufacturers encode the manufacture date. Look at the fittings on top for rust and white crust. Feel around the base for damp. Run a hot tap into a white bucket to see the colour.
Rust at the cold inlet fitting is often the first visible sign of a tank near its end.
Repair or replace?
| Problem | Usually |
|---|---|
| Thermocouple, element, thermostat | Repair |
| Relief valve | Repair |
| Tank body leak | Replace |
| Older tank with repeated faults | Replace |
Planning a replacement
Measure the space and doorways, note the vent type and fuel, and think about whether your household needs more or less capacity. Read tank vs tankless, then call (365) 387-8531.
Stop and call a plumber if
- Pilot will not stay lit, or elements trip the breaker
- Hot water runs out halfway through one shower
- Rumbling or popping from the tank as the burner fires
Common questions
Is a weeping tank repairable?
Water from the shell itself means the lining and steel have failed. Only replacement fixes that.
