How the job is handled
Sizing starts with how your household uses hot water: number of bathrooms, simultaneous showers, and large tubs. We compare conventional atmospheric vent, power-vented and direct-vent options because venting often decides what fits your house. A power-vented unit, for example, needs an electrical outlet nearby.
We drain and haul out the retired tank, set its replacement level with proper clearances, and connections, venting and gas lines are tested. Gas work is done by appropriately certified technicians.
Signs you need this work
- Tank is leaking from the shell or bottom seam
- Rust-coloured hot water from every tap
- Repeated burner or venting faults
- Tank is near or past its expected service life
What the plumber brings
Tools and parts that come in from the truck for this kind of call, so the fix can usually be made on the first visit:
- Gas leak detector and soap solution
- Appliance dolly and straps
- Venting pieces matched to the new unit
- Expansion tank and new relief valve line
The job, step by step
- 01
Gas is shut at the appliance valve and the cold supply is closed
- 02
The old tank is emptied by hose into the floor drain
- 03
Gas, water and vent are disconnected and the old tank is removed
- 04
The replacement is stood in place, piped, vented and bubble-tested
- 05
Burner is lit, draft is checked at the vent and hot water is confirmed at a tap
Symptom, cause and fix
| What you see | Usual cause | What we do |
|---|---|---|
| Atmospheric vent tank | Uses the existing chimney or B-vent | Like-for-like swap if the vent is sound |
| Power-vent tank | Vents sideways through the wall with a fan | Needs a plug and correct PVC venting |
| Rental tank removal | Owned by a rental company | Arrange return with the company before swapping |
Local card: Whitby houses
If your current heater is a rental, the rental company must be contacted about returning the old tank and closing the agreement. Read the terms first, as some agreements include buyout or removal conditions.
The visit, in order
- Household use and venting assessed
- Model and size confirmed with you
- Old tank removed and new tank installed
- Gas, venting and water connections tested
Ring us when
Plan replacement before failure if your tank is old. Waiting until it leaks often means a wet basement and fewer choices.
Common questions
Should I switch to tankless?
It can suit homes with high demand and space limits, but it costs more up front and may need gas line upgrades. We compare both honestly.
Is installation a long job?
Swapping one tank for a similar one usually fits in a single visit. Changes to venting or gas lines can add time.
