A broken main sewer line affects your whole home. Catching the warning signs early can save you from a messy backup and a bigger repair bill.
1. Several drains back up at once
One slow sink is a local clog. When toilets, tubs and floor drains back up together, the main line is the likely problem.
2. Gurgling toilets and drains
Gurgling when other fixtures run means air is being pushed through a partly blocked or broken line.
3. Sewage smells inside or outside
A healthy sewer system is sealed. Persistent odors suggest a crack or leak.
4. Soggy, green or sunken yard spots
A leaking lateral feeds the soil above it, creating extra-green patches or soft, sunken areas.
5. Clogs that keep coming back
If cleaning helps for a few weeks or months, roots or a break are probably letting debris collect.
6. Water in the lowest drain
Water rising in a shower or floor drain when you flush means waste cannot get past a blockage.
7. Pests near drains or foundations
Rodents and insects use broken sewer lines as highways into homes.
