Sisäviemäri

Sisäviemäri refers to the internal drainage system within a building that collects and transports wastewater and greywater to the main sewer line or a septic system. It is a critical component of a building's plumbing infrastructure, ensuring hygienic conditions and preventing the accumulation of waste. The system comprises a network of pipes, fittings, traps, and vents.

Wastewater from toilets, sinks, showers, and washing machines flows through these pipes. Each fixture is typically connected to a trap, a U-shaped section of pipe that holds water. This water seal prevents sewer gases from entering the building. Vent pipes are also an integral part of the system. They extend upwards, often through the roof, and are crucial for equalizing air pressure within the drainage pipes. This pressure equalization allows wastewater to flow smoothly and prevents the water seals in traps from being siphoned out.

The pipes used in sisäviemäri systems are generally made of durable materials like PVC, cast iron, or copper. The gradient of the pipes is carefully designed to ensure gravity-driven flow. Proper installation, maintenance, and adherence to building codes are essential for the efficient and safe operation of a sisäviemäri system. Blockages, leaks, or improper ventilation can lead to significant problems, including foul odors, unsanitary conditions, and structural damage. Regular inspection and cleaning can help prevent these issues.
