Leaks and water lines
Water spreading through a room or a valve that will not shut off may need urgent attention. The first step is to determine what can be isolated safely and what needs to be examined on site.
Need a plumber in Verdun for a plumbing emergency, a leak in your unit, a basement drain backing up, or a leaking hot water tank? If the situation is urgent, tell us where the water is spreading and whether it can be shut off safely. Plomberie Anjou also receives requests for planned work across Wellington–De L’Église, Desmarchais–Crawford and Nuns’ Island (L’Île-des-Sœurs).
If water is spreading, say so when you call. Do not reach for a shutoff valve through an area with an electrical hazard.

If you need an emergency plumber in Verdun, start with what is happening now: water that will not stop, wastewater coming up, or more than one unit affected. For a planned repair, the location and access still matter. You do not need to diagnose the fault before calling.
Tell us whether the leak is visible, whether an indoor shutoff valve works, and whether water has reached another room or unit. A stain on a ceiling may be some distance from the source.
Name the fixtures involved and when the problem occurs. Several drains reacting together call for a different assessment from a single slow sink.
If the pipe, valve or mechanical room is in a common area, contact the person who can provide access. That helps prepare a useful visit from the outset.
This local page helps you describe what is happening. The service pages explain the possible work and the checks involved in each type of visit.
Water spreading through a room or a valve that will not shut off may need urgent attention. The first step is to determine what can be isolated safely and what needs to be examined on site.
A single clog is different from wastewater rising in a basement. An active backup is urgent. Tell us which fixtures are affected and stop using the affected drains.
When a drain repeatedly clogs or the cause remains unclear, a camera inspection may help assess an accessible pipe before choosing the next step.
Describe any leak, loss of hot water or unusual sound. If you know the tank’s location and capacity, include those details. An on-site assessment determines whether repair or replacement makes sense.
The City identifies Wellington–De L’Église, Desmarchais–Crawford and L’Île-des-Sœurs as parts of Verdun. The building and the pipe’s location affect how a plumbing visit should be prepared.
In a duplex or plex, a drain stack or water line may serve more than one unit. If the same problem appears on another floor, mention it and arrange basement access when possible.
On Nuns’ Island and elsewhere in Verdun, if the valve or pipe to be examined is in a shared mechanical room, contact the person responsible for access and work authorization.
For premises on a commercial street such as Wellington, explain which fixtures cannot be used, whether water is on the floor, and when the plumbing can be reached.
Some work depends on an exterior water shutoff or on the sewer connection leading to the street. Tell us what can be accessed indoors so the next step and any municipal request can be assessed.
If the water cannot be stopped inside, the City explains how to request an exterior shutoff or valve location. The owner or an authorized representative may need to make the request and be present.
A blocked line beneath the street does not automatically mean the City will repair it. Montréal lists the conditions for a structural issue and the inspection documents required for a request.
Describe what you see, even if you do not know the cause. For an emergency, lead with active water, a backup or an immediate hazard. For planned work, these details help arrange access.
The reviews below describe individual experiences. They can help you understand the service received, but they do not guarantee a response time, diagnosis or outcome for a new request in Verdun.
A few answers to help you prepare without taking a fixture apart or assuming you know the source of the trouble.
No. The affected fixture, how often it clogs and whether other drains react help determine the approach. A camera can be more useful when a blockage returns or the condition of a pipe needs to be checked.
It could, but an assessment is needed to establish the source. Mention any other rooms or units affected and the location of accessible shutoffs. In a condo or rental building, alert the person who manages common areas.
If water is flowing, call and explain what is happening. Do not enter an unsafe area to reach a valve. Depending on the cause and access, an exterior shutoff may require a City request from the owner or an authorized representative.
Share the address, building type, fixture or pipe involved, your availability and the person who can authorize access. Photos may help when they show a label, valve or affected area, but they cannot replace an on-site assessment.
