Sewer smells, slow drains and blockages: when to call for help

Persistent sewer odours, multiple slow drains or water backing up through a fitting can indicate a problem beyond one sink or toilet. Avoid adding strong chemicals or flushing unsuitable materials to force the issue.

Keep children and pets away from wastewater, ventilate the area if possible and note which fixtures are affected. If water is backing up, contact a plumbing professional promptly.

Explain whether the issue started suddenly, follows rainfall or affects indoor and outdoor drainage. Those details help determine the most appropriate next step.
