In most Vancouver-area houses, the main water shut-off valve sits inside the home, on the wall where the water line enters the building. That is usually the front wall of the basement or crawl space, a mechanical room, a utility closet, or next to the water meter. In a condo, the suite valve is often in a bathroom vanity, an entry closet or a utility closet. Find it before you need it, test it, and label it.
TL;DR
- Look first where the water line enters the building: the front basement or crawl-space wall, a mechanical room, a utility closet, or near the meter.
- Slab-on-grade homes and condos hide the valve elsewhere: near the water heater, in the laundry area, or in a vanity or closet.
- Wheel (gate) valves close clockwise over several turns. Lever (ball) valves close with a quarter turn, until the handle sits across the pipe.
- If the indoor valve is missing or seized, the City of Vancouver can shut the water at the property line. Never force a stuck valve.
- Tenants and strata owners should tell the landlord or building management right away and never open locked mechanical rooms.

Where the main valve usually is
The City of Vancouver advises starting where the service line enters the building. Exact locations vary with construction and renovation history, so treat the list below as a search order, not a guarantee.
Houses with a basement or crawl space
This is the most common layout in older Vancouver, Burnaby, Richmond and New Westminster homes. Go to the wall that faces the street. Find the cold-water pipe coming through the foundation wall or, in some homes, up through the concrete floor. The valve is normally within a short distance of where that pipe enters, often just before or after the water meter.
If you have a finished basement, check behind access panels, in the furnace or utility room, and inside storage closets. Renovations often box in plumbing, and the valve can end up behind a small hatch.
Slab-on-grade homes
Without a basement, there is no obvious wall to follow. The same City guidance says to also check near the water heater, the laundry area and under sinks. Trace the cold line feeding the water heater back toward the wall where the water arrives. In many homes the valve is a short distance from the heater.
Condos and townhouses
In a condominium, the suite valve may be in a bathroom vanity, an entry closet or a utility closet. Building-wide valves are controlled by strata or building management. If water is coming from a neighbouring unit or a common pipe, call the property manager or strata emergency line. Do not go looking for riser valves in locked rooms.
Rentals and commercial space
If you rent, ask your landlord at move-in where the shut-off is and whether you are allowed to operate it. For small businesses in shared buildings, the answer is often a valve in a back-of-house utility room. Property managers with multiple units should record each valve location in the building file, not in one person’s memory.
How to confirm you have the right valve
Several valves can look alike. Under every sink, toilet and appliance there is a small fixture valve, and it only isolates that one fixture. The main valve is on the pipe that carries water into the home, usually the largest cold line.
WSSC Water, a utility in Maryland, gives a simple method that applies equally well here. Trace the incoming pipe to the meter, then test the suspected valve briefly: close it, open a faucet, and confirm that flow stops throughout the home. Then reopen it.
Two cautions:
- A pressure-reducing valve is a bell-shaped brass fitting that can sit close to the main valve. It is not a shut-off. Leave it alone.
- Don’t touch the City meter or the City’s valve at the property line. Request City assistance when the property-line shut-off is needed.
Which way to turn it
“Turn it right” is incomplete advice, because the answer depends on the handle. WSSC describes the two common types:
| Handle | Valve type | To close | To reopen |
|---|---|---|---|
| Round wheel | Gate valve | Clockwise, usually several full turns, until snug | Counterclockwise, slowly |
| Straight lever | Ball valve | Quarter turn, until the handle is perpendicular to the pipe | Quarter turn back, until the handle is aligned with the pipe |
WSSC’s guidance also covers restarting. After reopening, check for leaks at the valve and release trapped air through a faucet. Open a faucet on the highest level first to relieve pressure, then open others as needed.
When the valve won’t move
Old gate valves that haven’t been turned in years can seize. More force is not the answer: forcing an old valve can damage the stem or create a new leak at the valve itself. If it will not close with moderate, steady hand pressure, stop and use the property-line shut-off while a plumber replaces the valve.
Shutting off water to the house in an emergency
Speed matters when a pipe bursts or a supply line lets go. The order below follows PreparedBC’s emergency planning guidance, which says households should know how to turn off main utilities before an emergency, and the City guidance above.
- Close the main valve first. Don’t spend time mopping or hunting for the leak.
- Open a faucet at the lowest point (and the highest, to relieve pressure) to drain what remains in the lines.
- Cut power to affected electrical equipment only if it is safe to do so. If water is near outlets, panels or appliances and you would have to stand in water to reach the breaker, don’t. Call an electrician or your utility.
- Protect equipment before draining. WSSC advises de-energizing an electric water heater and addressing boiler or gas water heater settings before the system is drained down. If you aren’t sure how, call a plumber.
- Move valuables out of the water’s path and photograph the damage for your insurer.
- Call a licensed emergency plumber and, if you rent, your landlord or property manager.
We cover the stages that follow in our emergency plumbing repair process guide, and our piece on types of household plumbing emergencies helps you judge what you are dealing with.
A burst water heater is a special case
A failed tank can release dozens of gallons quickly. Closing the main stops the refill, and shutting the heater’s own cold inlet valve and its power or gas supply is the next step. This homeowner walkthrough of what to do when a water heater bursts explains the cleanup side. For the repair or replacement itself, that is a job for a licensed plumber.
When the indoor valve fails: the City’s shut-off
There are two shut-off points on a Vancouver property, and they belong to different parties. The City owns the service from the water main to the curb stop. The property owner owns the service from the curb stop into the building.
If you can’t find or operate the indoor valve, the City can locate and operate the property-line shut-off. According to the City of Vancouver:
- Owners can borrow a water-line shut-off key free for up to 48 hours, for lines 50 mm (2 inches) or smaller.
- Lines 75 mm (3 inches) or larger require a City crew.
- A crew visit may generate charges.
Other municipalities in Greater Vancouver run their own programs, so check with your city’s utilities department if you live in Richmond, Burnaby, New Westminster or the North Shore. The Vancouver details above should not be assumed to apply there.
Who pays for the leak
Where the leak is decides who is responsible. A leak on the owner’s side of the curb stop is the property owner’s responsibility. The City’s water and sewer repair cost guidance says owners are not charged when the source of a leak on private property is determined to be on the City-owned portion of the line. Before you call anyone, work out which side of the curb stop the water is coming from. That tells you whether the right call is a plumber or the City.
Tenants, strata owners and managers
PreparedBC points out that posting shut-off instructions matters most where the person who discovers a leak may not be the owner. That describes rentals, businesses and multi-occupant buildings.
If you are a tenant:
- Ask where the suite valve is when you move in, and note it down.
- If a pipe lets go, close the suite valve if you can reach it, then notify the landlord or property manager promptly.
- Don’t enter locked mechanical rooms or operate building-wide valves without authorization.
If you manage property:
- Put a laminated tag on each valve and a floor plan in the building file.
- Give after-hours staff and on-call contractors the same information.
- Exercise each valve once a year (a quarter turn or a few rotations, then back), so it doesn’t seize.
Our guide to common rental property plumbing failures lists the problems that most often send tenants looking for this valve.
Label it, test it, plan for it
A ten-minute job now saves a frantic search later.
- Find the valve using the search order above.
- Close it, open a faucet, confirm the flow stops, then reopen the valve slowly.
- Mark it with a durable label and keep the area clear. Don’t stack boxes in front of it.
- Write the instructions down and post them where everyone in the household can see them, as PreparedBC recommends.
- Show every adult and older child. Teach them wheel or lever.
- Note the property-line shut-off location and whether you would need the City.
If your valve is a hard-to-turn gate valve, consider asking a plumber to replace it with a full-port ball valve, which closes in a quarter turn. It is far easier to use in a panic. New and permitted plumbing work in BC falls under the 2024 BC Plumbing Code, which applies to building-permit applications submitted on or after March 8, 2024. A plumber should confirm current permit and installation requirements for your job.
Our perspective: the valve nobody has touched
In our work across Vancouver, Richmond, New Westminster and Burnaby, the most common surprise is not a missing valve. It is a valve that exists but has not been operated for years, and that nobody in the house can identify. By the time water is on the floor, that is the worst moment to learn it.
Our advice is plain. Know where the valve is, know whether it is a wheel or a lever, and know that it works. If it does not close fully or it weeps at the stem, replace it as planned work, not as part of an emergency. Replacing a failing valve on a quiet afternoon is a small job. Doing it with the water running is not.
We also tell people not to fight a stuck valve. Close what you can, use the City’s property-line shut-off if needed, and call us. We would sooner replace a valve than a ruptured stem and the ceiling below it.

Frequently asked questions
Where is the main water shut-off valve typically located in a home?
Usually inside, on the wall where the water line enters the building: the front basement or crawl-space wall, a mechanical room, a utility closet, or near the meter. In slab homes, check near the water heater, the laundry area and under sinks. In condos, look in a bathroom vanity, entry closet or utility closet.
How do I know I’ve found the main valve and not a fixture valve?
The main valve is on the large cold-water pipe entering the home, often near the meter. Close it, then open a faucet. If the flow stops throughout the house, it is the right one. A valve under a sink or behind a toilet only isolates that one fixture.
Which way do I turn the main water shut-off?
It depends on the handle. A round wheel closes clockwise, usually over several turns. A lever closes with a quarter turn, until the handle is perpendicular to the pipe. If it resists, stop rather than forcing it.
What if I can’t find or turn the valve in Vancouver?
The City of Vancouver can shut off water at the property line. You can borrow a shut-off key free for up to 48 hours if your line is 50 mm (2 inches) or smaller, or request a City crew, which may involve charges. Call a plumber to fix or replace the failed indoor valve.
