Pin down the affected drain
A slow bathroom basin in a Vancouver apartment may be a fixture-level problem. Wastewater rising in a shower when a toilet is flushed can point to a different section of the system. Tell us when the symptom began, which drains are involved and whether it has returned after previous cleaning.
Access and next steps
In a strata or rental building, the affected pipe may be shared. Building management may need to coordinate access or confirm responsibility before work starts. We can explain whether cleaning, a camera inspection or another assessment is the sensible next step. For an active sewage backup, avoid using the affected fixtures and call directly.
Record what happens when another fixture runs
If flushing a toilet makes a shower drain rise, or a washing machine causes water to appear at a floor drain, note that connection. It can help distinguish a local fixture clog from a problem farther along the line. In a Vancouver building, ask whether nearby units have seen the same thing and pass that information to management. Please do not keep testing an active backup by running more water; call and describe the pattern you have already observed.
