Advice that helps you make the next decision
A plumbing guide should do more than repeat a service description. It should help you understand what the symptom may mean, what information to collect and where a do-it-yourself check should stop.
A direct answer
Each guide begins with the observable signs and the safest useful first step.
A clear boundary
We distinguish simple observations from work that requires tools, access or a licensed contractor.
Quebec context
Code, public-health or municipal information is linked to an official source when it matters.
Start with the symptom
Choose the situation closest to what you see
You do not need to diagnose the plumbing system yourself. Begin with what is happening now; the appropriate service can be determined from there.
Water supply
Water is visible or continues to flow
If an accessible shutoff can be used safely, stop the water and protect the surrounding area. Keep away from wet electrical equipment. An active or spreading leak should be reported promptly.
Drainage
A fixture drains slowly, gurgles or backs up
One affected fixture often points to a local branch. Several fixtures reacting together, sewage odours or wastewater at the lowest drain can indicate a problem farther along the system.
Basement protection
Water appears near the floor drain or sump
Stop using plumbing fixtures if wastewater is backing up and avoid contact with contaminated water. Backwater valves and sump pumps have different roles, so the source of the water matters.
Hot water
Hot water changes or disappears
Note whether the change affects every fixture, when it began and whether the electric water heater shows visible leakage. Do not remove panels or touch wet electrical components.
