Signs a drain problem may be more than a simple clog
A single slow sink can have a local blockage, while several slow drains may point to a concern farther along the drainage system. Gurgling, water returning through another fixture, sewage odors, and recurring clogs are details worth reporting.
Repeatedly forcing the same drain with store-bought chemicals does not explain why the problem returns. It can also make the area more hazardous to inspect or work on.
- Water drains slowly or stands in the fixture
- Toilets bubble when another fixture drains
- More than one room has drainage trouble
- Odors or backup appear after water use
