An old gas water heater is safely disconnected and drained before removal, and its steel tank is typically recycled through a metal facility.

Quick answer
An old gas water heater is disposed of by first having a licensed gas fitter shut off and disconnect the gas supply and venting, then draining the tank of water and any sediment before it's removed from the home. Once out, the steel tank is generally recycled through a metal recycling facility, since a water heater is almost entirely steel with a small amount of insulation and plastic components. Removal and recycling should be confirmed as included in your replacement quote so you aren't left arranging it separately.

Before an old gas water heater can be removed, the gas supply is shut off and disconnected by a licensed gas fitter, and the venting is detached. The tank is then drained, which in older units can reveal years of sediment build-up, particularly in areas served by well water in parts of the Fraser Valley where mineral content is higher than Metro Vancouver's soft reservoir supply. That sediment doesn't affect disposal safety, but it's a useful reminder of why periodic tank flushing during the unit's life helps it perform better and last longer.
Disconnecting the gas line is not a task for a homeowner or a general contractor. It requires the same Technical Safety BC licensing used for installing the replacement unit, since an improperly capped or left-open gas connection is a genuine hazard.
A drained gas water heater is still heavy, and in many Metro Vancouver homes it's installed in a closet, crawl space, or a tight utility area that wasn't designed with future removal in mind. Stairs, narrow doorways, and low headroom in older character homes can add time to this step. If your unit is in an unusually tight space, mentioning that when you book your replacement helps the installer plan enough time and the right equipment for a safe removal.
| Approach | What to know |
|---|---|
| Installer removes and recycles | Standard practice, confirm it's stated in the written quote |
| Homeowner arranges separately | Adds cost, time, and coordination that most homeowners would rather avoid |
| Old unit left behind | Creates a heavy disposal problem later and may run against municipal waste rules |
A written quote for a water heater replacement should explicitly state whether removal and recycling of the old unit is included, since this is a common area where an otherwise low quote turns out to have a gap.
Clear a path from the water heater's location to the nearest exit, remove anything stored around or on top of the unit, and mention any unusual access challenges when you book. None of these steps require special tools or licensing on your part, but they help the crew work efficiently and safely on the day of the job.
Scheduling the removal of an old water heater alongside the new installation, rather than as a separate visit, is the norm and keeps your household without hot water for the shortest possible window. If your old unit has been leaking or showing visible corrosion at the base, mention that when you book, since it can affect how carefully the technician handles the drain and removal to avoid tracking water through the home. A little extra notice about the unit's condition helps the crew bring the right equipment for the job on the first visit rather than needing a follow-up.
Safety note
Disconnecting a gas water heater's supply line and venting must be done by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870. If you ever smell gas during or after a water heater is removed, leave the home and call FortisBC at 1-800-663-9911.
Typically yes; confirm removal and recycling are explicitly included in your written replacement quote.
No, disconnecting the gas line requires a Technical Safety BC licensed gas fitter, even though draining water is not itself gas-related work.
The steel tank shell is the main recyclable component; it's generally taken to a metal recycling facility along with other scrap metal.
Mineral content in the water supply, along with normal years of use, causes sediment build-up inside a tank over time; it's more common with well water sources than Metro Vancouver's soft reservoir supply.
Yes, a unit in a cramped closet or crawl space takes longer to remove safely than one in an open utility room; mention this when booking.
Most replacement quotes include removal and disposal as part of the overall price; ask specifically if it isn't stated.
