Your main sewer line carries every drop of waste water out of the house. When it starts to block, the signs are often subtle at first.
1. Several drains are slow at once
One slow sink is a local clog. A slow tub, sink and toilet together usually means the problem is further downstream.
2. Gurgling from unexpected places
If your toilet gurgles when the washing machine drains, air is being pushed through the system by water that can't get past a restriction.
3. Water at the basement floor drain
The lowest drain in the house is where water appears first when the main line is backed up.
4. Sewage smells
Persistent sewer odours inside — or in the yard above where the line runs — deserve attention.
5. Lush or soggy patches in the yard
An unusually green or wet strip of lawn can indicate a leaking line below.
