Gas tank checks
- Look through the sight glass near the bottom of the tank. A small blue flame means the pilot is lit.
- Check the gas control knob is on ON, not PILOT or VACATION.
- Make sure the gas cock on the supply pipe is in line with the pipe (open).
- On power-vent units, check the plug and the breaker for the blower on top of the tank.
- If the pilot is out, follow the lighting instructions on the tank label if the steps make sense to you.
Smell gas? No lighters, no switches. Get everyone outside, and only from the driveway dial the gas utility.
Electric tank checks
- Check the breaker. Electric heaters are on a double-pole breaker; a tripped one sits in the middle position.
- If it trips again right away, leave it off. That is an element or wiring fault.
- Some tanks have a red high-limit reset button behind the upper access panel. Only press it with the breaker off and the cover handled carefully, or leave it to us.

Signs the tank itself is done
- Water pooling under the tank or dripping from the bottom seam.
- Rust-coloured hot water only.
- Rumbling or popping from heavy sediment.
- Water from the relief valve pipe that will not stop.
| What you find | Usual cause |
|---|---|
| Pilot out, relights and stays | Thermocouple or draft issue worth checking |
| Pilot will not stay lit | Thermocouple or gas control |
| Breaker trips | Element shorted |
| Leak at the base | Tank failure, plan a replacement |
If the tank is leaking
Turn the gas knob to OFF or switch off the breaker, shut the cold supply valve feeding the tank, and put a pail or towels down. Many Vaughan tanks are rentals; if yours is, your rental provider may be the first call. If you own it, see water heater repair and gas water heater replacement.
Questions from callers
How long does a tank take to reheat?
Usually under an hour for a gas tank after it relights; electric takes longer.
Can I relight the pilot on my own?
If the label instructions are clear and there is no gas smell, many homeowners do. If unsure, call.
Why is there only lukewarm water?
A failed dip tube, a bad element on an electric tank, or a mixing valve set too low.
