From older Maillardville homes to new Burke Mountain builds, gas water heater inspections in Coquitlam cover the same fundamentals with a few local wrinkles.

Quick answer
A gas water heater safety inspection checks the venting for integrity and correct routing, confirms clean combustion at the burner, tests the gas connection for leaks, and verifies the pressure relief valve and shutoff are functioning and accessible, all performed by a Technical Safety BC licensed gas fitter. In Coquitlam, the same core checklist applies whether the home is an older property in Maillardville or a newer build on the hillside, but the specifics of what a technician is watching for, aging components versus commissioning issues, differ by age of the installation.

Every gas water heater inspection starts with the venting: confirming the flue or power vent is intact, properly pitched or routed, and clear of blockage or corrosion, since this is the most direct link to combustion safety. From there, the technician checks the burner assembly for clean combustion, tests the gas line connection for leaks, and confirms the pressure relief valve and main shutoff are both functioning and reachable without tools.
Tank condition rounds out the inspection: checking for corrosion or leaking at the base and fittings, and assessing anode rod wear where the design allows access, since the anode is a sacrificial component meant to corrode in place of the tank itself.
A number of post-war and 1970s-era homes in Maillardville and Austin Heights have had their water heater replaced at least once over the decades, sometimes with venting or gas connection work from a previous era that hasn't been reassessed against current standards since. An inspection on one of these properties checks that the venting configuration still matches the appliance actually installed, since a mismatch between an older flue setup and a newer, different type of water heater is one of the more common issues found in established neighbourhoods.
Water heaters in newer Westwood Plateau and Burke Mountain homes are less likely to show age-related wear, but a below-grade or tightly enclosed mechanical room, more common in these newer builds, needs adequate combustion air for the appliance, and this is worth confirming during an inspection rather than assuming it was set up correctly at construction. A laneway home with its own gas water heater also needs its venting and combustion air assessed independently from the main house, not assumed to be equivalent.
| Item | What's checked |
|---|---|
| Venting | Intact, correctly routed, matches the installed appliance |
| Combustion | Clean burn at the burner assembly |
| Gas connection | No leaks at fittings |
| Pressure relief valve | Functioning and unobstructed |
| Anode rod | Condition checked where accessible |
| Combustion air | Confirmed adequate, especially in below-grade or enclosed spaces |
An annual inspection is a reasonable baseline for any gas water heater in Coquitlam, regardless of the home's age. Any noticeable change, reduced hot water temperature, unusual sound, or visible moisture near the base of the tank, is worth a prompt inspection rather than waiting for the annual visit to come around.
Safety note
A gas water heater safety inspection, including checks of the gas connection, venting, and combustion, must be performed by a Technical Safety BC licensed gas fitter. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450. If you ever smell gas near the water heater, leave the home and call FortisBC at 1-800-663-9911.
A mismatch between an older venting configuration and a newer water heater that's since replaced it is one of the more common findings in established neighbourhoods like Maillardville.
Yes. Age doesn't exempt an appliance from needing its pressure relief valve, gas connection, and combustion air checked on a regular basis.
Yes, it should be assessed as its own independent system with its own venting and combustion air, not assumed to match the main house's setup.
An annual inspection is a reasonable baseline for most homes, with a prompt check any time there's a noticeable change in performance or sound.
Whether the mechanical room, particularly if it's below grade or tightly enclosed, has enough air supply for the appliance to combust safely.
It's checked where the water heater's design allows access; the anode is a sacrificial part meant to corrode instead of the tank itself, so its condition matters for tank longevity.
