Pääviemäri

Pääviemäri, also known as the main sewer line or the building drain, is a crucial component of a plumbing system. It is the primary pipe that collects wastewater from all the drains within a building and carries it away to the municipal sewer system or a private septic system. This pipe typically originates from the lowest point of the building's plumbing, often near the foundation, and extends underground to its connection point with the public sewer main or septic tank.

The Pääviemäri is usually a larger diameter pipe than the individual drain pipes within the building to accommodate the combined flow of wastewater. Its proper functioning is essential for preventing sewage backups, unpleasant odors, and potential health hazards within the property. Blockages or damage to the Pääviemäri can lead to significant plumbing issues that require professional attention.

Maintenance of the Pääviemäri often involves periodic inspections and occasional cleaning to remove accumulated debris, grease, or roots that may have infiltrated the pipe. Understanding the location and condition of the Pääviemäri is important for homeowners and building managers to ensure the efficient and safe disposal of wastewater.
