A plug is a device to temporarily blank a sewer or a house connection.
Most plugs are manufactured with rubber and sometimes reinforced with metal frames to grant better resistance to pressure.
Plugs are often used to :
- blank a sewer network
- isolate a pipe section
- lead air and water tightness tests

There are several plugs to suit any situation :
- plugs for main sewers
- plugs for house connections
- plugs for manholes
- plugs for larger flows
- plugs for high pressure
- plugs for egg shape pipes
