Gas tanks
- On older standing-pilot heaters, a pilot that keeps going out usually points at a tired thermocouple. On newer models with flame sensors and electronic ignition, a clogged flame arrestor screen under the burner can starve the burner of air and trip a safety lockout. We clean, test and replace in that order.
- Power-vented gas heaters, common in Richmond Hill homes where the tank vents out a side wall, add a fan and a pressure switch. A blocked vent or a failed switch shuts the heater down. We check the vent termination outside, especially after snowfall.
Electric tanks
- An electric heater has two elements and two thermostats. If you get a short burst of hot water and then cold, the lower element has usually failed. If there is no hot water at all, the upper element or the high-limit switch has tripped. We test each with a meter and replace only the failed part.
- Before any element is replaced, the tank is drained below the element level. We flush sediment at the same time, since sediment is a common reason elements fail early.
Signs you need this
- No hot water at all
- The hot water lasts half as long as it used to
- Rumbling or popping from the tank
- A puddle around the tank base
- Pilot light will not stay lit
Leaks
- Water at the base of a tank may be from the T&P relief valve, the drain cock, a fitting on top, or the tank itself. Valves and fittings can be fixed. A leaking tank cannot; it means the inner lining has failed and the tank needs replacing.
- Many Richmond Hill homes have rental water heaters. Rented tanks are fixed by the company that owns them; check the label on the tank and call them. If you own it, we are glad to repair it.
How the job runs
- 1
We confirm the fuel or power supply to the tank.
- 2
Ignition, burners or elements are tested in order.
- 3
The failed part is replaced and the tank is flushed if needed.
- 4
Hot water is restored and temperature is checked at a tap.
Richmond Hill note: most houses here sit on York Region municipal water with fairly hard supply, and many basements have a floor drain tied to the sanitary lateral. Mention both on the phone; it changes what goes on the truck.
