City Water Leak Notice · For homeowners & residential landlords
The city says your home has a leak. Here's how to make that letter cheap.
A residential leak notice almost always means one thing: water has been moving through your meter non-stop, and the utility's system noticed before you did. For homes, the usual suspects are the buried service line between the meter and the house, a running indoor fixture, the irrigation system, or — in slab-on-grade homes — a pipe under the concrete. None of them announce themselves; all of them show up on the meter.

The path from letter to closed file is short when it's done in order: confirm at the meter, split inside from outside with the main shut-off, pinpoint professionally, repair small, and submit the documentation. Many BC utilities offer a leak adjustment on the bill for promptly repaired, documented leaks — done right, the adjustment and the avoided waste cover much of what the whole exercise costs.
What's usually behind the notice
- Buried service line leaks between meter and house — invisible at the surface, often for months
- Running indoor fixtures quietly passing water around the clock
- Irrigation systems: cracked laterals, weeping valves, a zone that never fully closes
- Slab leaks in homes with in-floor plumbing — warm spots and high bills before any visible water
- Pool, spa, and water-feature auto-fill systems concealing a real loss
- Aging poly-B or galvanized supply piping at end-of-life
Why the clock matters
- Service-line leaks commonly waste thousands of litres per day — billed to you
- Saturated ground undermines driveways, slabs, and foundations over time
- Adjustment programs typically require prompt, documented repair — slow responses forfeit money
- Insurance outcomes are better with early, professionally documented action
From letter to closed file
- 1
Read the notice properly
Note what triggered it (continuous flow, abnormal consumption, estimated vs actual read), any response window it sets, and whether it mentions a leak adjustment program. Keep the letter — it becomes part of your adjustment and insurance paper trail.
- 2
Run the meter test
Shut every fixture and water-using appliance off, then watch your water meter for five minutes. Movement with everything off confirms water is leaving the system somewhere on your side. Our free DIY tool at test.leak.ca walks you through it step by step.

Split inside from outside
Close the building's main shut-off valve and read the meter again. Still moving? The leak is between the meter and the building — usually the buried service line or irrigation. Stopped? It's inside: running fixtures, a slab leak, or concealed plumbing.

Get it located, not guessed at
This is where we come in: acoustic, thermal, and tracer-gas methods pinpoint the leak — service line, slab, irrigation, or in-wall — typically within centimetres, before anyone excavates or opens finishes. One precise location instead of exploratory holes.
- 5
Repair with the right trade
Your plumber or excavation contractor repairs exactly where the mark says. Because the location is precise, the repair is small — and fast enough to matter for any response window your notice set.

Document everything for the adjustment
Many BC utilities offer a leak adjustment on the bill when a leak is repaired promptly and documented. Our written detection report plus your repair invoice is exactly the evidence package those applications ask for — and the same file supports an insurance claim if damage occurred.

ViewResidential owners ask
I got the letter but I can't see any water anywhere. Is it real?
Almost certainly — invisibility is the normal case, not the exception. Service-line leaks drain into subsoil, slab leaks evaporate or travel under flooring, and irrigation losses just look like watering. The meter doesn't speculate: if it spins with everything off, water is leaving. The split test (main valve closed vs open) then tells you inside versus outside in ten minutes.
Will my home insurance cover any of this?
Policies commonly cover resulting damage (what the water ruined) rather than the pipe repair itself, and insurers respond far better to early, documented action than to long-running neglect. Our detection report — dated, specific, professional — anchors both the claim file and the utility adjustment application. See our BC insurance claims guide for the full picture.
My house is older — does that change where you look first?
It sharpens the priors. Pre-1970s homes may still carry galvanized service lines at end-of-life; 1980s–90s construction brought poly-B piping with a known failure record; postwar neighbourhoods have mature trees whose roots find service-line joints. Era plus the split-test result usually narrows the hunt before equipment even comes off the truck.
Can I just wait for the next bill to see if it's serious?
You can — it's the most expensive monitoring plan available. Notice-level flow wastes water every hour while you wait, the billing cycle adds weeks, and adjustment programs reward promptness. A free five-minute meter check today tells you more than next month's bill will, for $0.
