What replacement covers
A gas tank heater is removed and a new one set in place, connected to cold supply, hot outlet, gas line and venting. Most Oakville homes have either a conventional atmospheric unit vented up a chimney or a power-vented unit that exhausts sideways through the wall with plastic pipe. The replacement must match the venting the house can support, or the venting must be changed to suit.

Why tanks wear out
Every tank has a sacrificial anode rod that corrodes in place of the steel. When the rod is spent, the tank itself begins to rust. Sediment from hard water settles on the bottom and makes the burner work harder. Most tanks give years of service, but once the bottom leaks, there is no repair.
Signs you need this now
- Tank older than its warranty with rust at the base
- Leaking from the tank body itself
- Rusty water from the hot side only
- Repeated repairs on the same unit
- Not enough hot water for the household any more
Things to check first
- Is the pilot lit, or does the unit show a status light error?
- Is the water on the floor coming from the tank, the relief valve pipe or a fitting above?
- Is the heater owned, or rented? Look for a rental company sticker. See rented water heaters.
If you smell gas, leave the home and call Enbridge Gas from outdoors. Do not operate switches.
The visit in five steps
- 1Close the gas cock and cold inlet, then drain the tank
- 2Unhook the vent connector, gas line and both water pipes
- 3Stand the new heater and pipe it in
- 4Fit the vent and sediment trap
- 5Fill, purge, light and test for leaks
The day of the swap
The old tank is drained and disconnected. The new one is placed on a stable base, piped with a new shut-off where needed, fitted with a temperature and pressure relief valve and a discharge pipe, and leak-tested on both gas and water sides. The burner is lit, venting is checked for proper draft, and you are shown how the controls work.
