A leak keeps running
If the indoor shutoff valve is accessible and working, close it without forcing it. Tell us whether the leak appears to come from a visible connection, an appliance, or the supply line.

Need a plumber in Rivière-des-Prairies–Pointe-aux-Trembles for a drain backing up, a leak that needs isolating, or a failing hot water tank? Plomberie Anjou takes requests across both neighbourhoods and the Bout-de-l’Île area, for urgent problems and planned work. Tell us what you noticed first so the right checks can be planned.
Before you call
A short, precise description helps more than a guessed diagnosis. Note where water appears and whether one fixture or several are affected.
If the indoor shutoff valve is accessible and working, close it without forcing it. Tell us whether the leak appears to come from a visible connection, an appliance, or the supply line.
Stop using fixtures connected to the affected drain. Let us know whether it is just one sink or whether the floor drain and other fixtures are reacting as well.
Look for water at a connection or around the tank without taking the unit apart. Mention how to access the hot water tank and whether water is near electrical equipment.

Services across the borough
Whether you need a Rivière-des-Prairies plumber or a Pointe-aux-Trembles plumber, the building’s actual plumbing layout matters. Access to the drain, valve, and fixtures shapes the work.
Drain cleaning may be enough for a localized blockage. If it keeps returning or affects several fixtures, a camera drain inspection can help establish the condition of the line after an initial assessment.
A leaking connection indoors differs from a problem on the main water service line. If the exterior service box must be shut off, that work needs to be coordinated with the borough.
After wastewater comes back through a fixture or floor drain, both the cause and the protection of fixtures below street level need attention. A backwater valve must also remain accessible for inspection and maintenance.
A leaking tank, loss of hot water, and a faulty connection do not always call for the same solution. The electric water heater, its condition, and its connections all affect the recommendation.
Basements and heavy rain
Both can happen after heavy rain, but they call for different checks. A wet basement alone does not establish that a sewer backup occurred.
The City of Montréal explains surface water entry and drainage risks. The first place you saw water is worth noting before a visit.
A sewer backup may be involved. Stop using the affected fixtures and identify every point where water appeared. A plumber can check the drainage system and the backwater valves where appropriate.
Water may be infiltrating or collecting on the surface. Note the entry point; the source has to be identified before plumbing work can be recommended.
A useful service visit
In a house, rental unit, or commercial space, available access and the number of affected fixtures shape what can be checked.
Show the first affected spot and then the other signs. A drain that has been slow for weeks and a sudden backup tell different stories.
The plumber examines accessible points and determines whether unclogging, a repair, or closer inspection makes sense. A camera is not automatic.
We distinguish work that can be done on site from work needing another access point, a part, or city coordination. The scope follows the findings.

Common questions
These answers help you prepare your call. The final diagnosis depends on the installation and what can be accessed on site.
No. A localized blockage may be cleared without one. If the blockage keeps returning, several fixtures are affected, or the condition of the pipe remains uncertain, the plumber may recommend a camera inspection after initial checks.
No. Note whether water rises from a drain or enters through an opening or wall. The City of Montréal describes these different entry paths; the source needs checking before work is chosen.
If planned work requires the exterior city service box to be shut off, the owner or the owner’s representative contacts the borough, including through 311. See the City of Montréal’s instructions for the address. An accessible indoor valve is a separate matter.
Yes. Plomberie Anjou takes urgent requests 24/7 at 514 312-1521. Give the address, describe the problem, and explain what access is available; service and timing are confirmed for the specific situation.
