1. Several drains are slow at once
One slow sink is usually a local clog. When the tub, toilet and basement drain all slow down together, the issue is more likely in the main line.
2. Gurgling toilets
A toilet that bubbles when you run the washing machine or drain the tub suggests air is being pushed through a partial blockage further down.
3. Sewer odours
Persistent sewer smells in the basement or yard can indicate a crack or break in the line, or a dried-out trap.
4. Lush or soggy patches outside
Leaking wastewater can fertilise the lawn above it, leaving a greener or wetter strip along the path of the sewer line.
5. Backups during heavy rain
If your basement drain backs up during storms, a camera inspection and a conversation about backwater valves are worth considering.
