Protect the area first
A plumbing emergency in Chambly?
An expanding leak, an overflowing toilet or sewage coming back into the building needs prompt attention. Start your call by explaining what is happening right now. An old, dry stain raises different questions from water actively spraying behind a wall. Also tell us if you have already shut off the water.
If you know the correct valve and can reach it safely, close the supply to the affected fixture. If the leak continues, shutting off the main supply may be necessary. Do not force a stuck valve. Stay away from water near electrical equipment and contact emergency services when there is an immediate danger.
For a backup, stop using fixtures connected to the affected drainage system. Keep children and pets away from wastewater. Repeated flushing can add water to an overflow, so avoid testing the toilet again and again. Our sewer backup page explains the symptoms worth reporting and the distinction between an urgent overflow and a recurring drainage problem.
Availability and the timing of a visit depend on your address, the access conditions and the situation. Do not delay an urgent call to take photos or search for building documents. Explain the immediate risk first.
