Clues that point to gas water heater replacement
- Water leaking from the body or the bottom seam of the tank
- Rusty hot water from every tap
- A tank older than about twelve years that now needs a major part
- Hot water that no longer covers a normal morning
Our method, in order
We begin by sizing the new heater to the house rather than simply matching the old label. A family that has added a basement bathroom or a soaker tub since the last tank went in may need a larger tank or one that reheats faster.
- Isolate gas and water, then drain and unhook the old tank.
- Look over the vent: atmospheric tanks rely on a sound chimney or B-vent; power-vented models exhaust through the wall with plastic pipe and need an electrical outlet.
- Stand the new tank on a level base, connect water with new fittings, add a thermal expansion tank where the plumbing calls for one, and pipe the relief valve to end a short way above the floor.
- Connect gas with a proper sediment trap and leak-test every joint.
- Light, set the temperature and confirm draft at the vent.
- Remove the old tank from your home.
Bench note
In Ontario, gas appliance work has to be carried out by a licensed gas technician. Confirm the credentials of anyone who connects or vents a gas heater in your home.
Newmarket houses and this job
When a high-efficiency furnace is installed, the old water heater sometimes ends up alone on a chimney that was sized for two appliances. That oversized flue can cool too much and condense. In those houses a power-vented tank, or a chimney liner, is often the better choice. We check this every time.
Basement layout matters too. Many homes in Stonehaven, Woodland Hill and other newer areas have the tank in a finished utility room with little space around it. We measure clearances before ordering so the new heater fits and stays serviceable.
Owners deciding between owning and renting can read our circular on renting or buying a water heater. If the rental agreement is still active, check its buyout terms before removing the tank.
Arranging a replacement
Call us with the label details and a photo of the venting if you can. We will tell you what fits and what is involved well before anything is disconnected.
Phoned-in questions
How many hours does the swap take?
A straight swap on the same venting usually takes part of a day. Changing to power venting takes longer.
Do I need an expansion tank?
If your home has a check valve or a pressure reducing valve on the main, an expansion tank protects the heater from pressure spikes. We check during the visit.
