Our Work ยท Hot Water
Gas Water Heater Replacement in Newmarket
Gas tanks give a lot of warning before they quit. When the warnings run out, we swap the unit, check the venting and gas line, and take the old one away.
- Same-visit diagnosis on gas and electric tanks
- Draft and gas-leak tests on every heater we touch
- Old tank drained, hauled and disposed of
- Owned or rented tanks both serviced
Cues for gas water heater replacement
- Rust-coloured water from the hot tap only.
- Moisture or a slow drip at the base of the tank, not the fittings.
- Popping and rumbling as the burner fires, from sediment baked on the bottom.
- Hot water that runs out noticeably faster than it used to.
- A pilot that will not stay lit even after the thermocouple has been looked at.
Age matters too. A tank past the age printed on its warranty is living on borrowed time, and a leak at the seam cannot be patched.
Water heater job sheet
- Tools on the truck
- Combustion analyser, manometer, multimeter, anode socket, drain hose and dolly
- Parts we check first
- Thermocouple or flame sensor, igniter, gas valve, elements, thermostat, T&P valve
- What we disconnect
- Gas at the appliance valve, venting at the draft hood, water at the unions
- How we prove it
- Draft test at the hood, leak test on the gas joints, a full tank to temperature
What fails inside the pipe, and why
York Region water carries enough minerals that sediment builds up inside tanks, especially those that have never been flushed. That layer insulates the water from the burner, so the unit works harder and the steel overheats. Many homes in subdivisions such as Stonehaven-Wyndham were built in a short window, which means their original heaters tend to reach the end of life at about the same time, street by street.
Plenty of local households also rent their tanks. If yours is a rental, the swap involves the rental company; see our page on electric replacement for the alternative fuel option if you are reconsidering.
On the job: tools, parts and steps
- We confirm the size you need from the household, the fixtures and the existing tank, rather than simply matching the old label.
- Gas is shut, the tank drained and disconnected.
- The new unit is set, the gas connection made and leak-tested, and the venting checked for correct slope and draft. Power-vented models need a nearby outlet and a clear path for the plastic vent.
- The temperature is set, a relief line run to within reach of the floor, and the old tank leaves with us.
What decides how big the job gets
The biggest swing is natural-draft versus power-vent. Converting between them changes the venting work. Tank size, a move to a different spot in the basement, and any corrections needed to an older gas line or chimney liner also change the figure. We quote the whole job up front. If you are weighing a different technology, read tank versus tankless before you decide.
Shut it off and call, or book it?
A tank that is actively leaking should be shut off at the cold inlet and the gas valve set to pilot or off, then replaced soon. A tank that is merely old and noisy gives you time to plan, compare models and book a convenient morning. Either way, the number is (365) 517-0623. Water near the tank can also reach a sump pit, so if the pit pump is acting up, look at sump pump repair too.
Asked on site
How long does a swap take?
A like-for-like replacement is normally done the same day. Venting changes or a move to a new location can stretch it.
Do I need a permit?
Gas appliance work is regulated in Ontario and must be done by a licensed gas technician. We handle the required paperwork for the work we do.
Should I flush my new tank?
Yes. Draining a few litres from the valve once or twice a year cuts down sediment from hard water and helps the tank last.
