Sisäviemärin

Sisäviemäri refers to the part of a building's plumbing system responsible for carrying wastewater and sewage from interior fixtures and appliances to the building's main sewer line or septic system. This system typically comprises a network of pipes, traps, and vents. The pipes are usually made of plastic (like PVC or ABS) or cast iron, designed to withstand the corrosive nature of wastewater and prevent leaks.

A crucial component of the sisäviemäri is the trap, commonly found under sinks and toilets. These traps hold a small amount of water, creating a water seal that prevents sewer gases from escaping into the building. Without these traps, unpleasant and potentially harmful odors would enter living spaces.

The venting system is another vital part of the sisäviemäri. Vent pipes, connected to the drainage system, allow air to enter the pipes. This air flow equalizes the pressure within the drainage system, preventing a vacuum from forming. A vacuum could otherwise siphon water out of the traps, compromising the water seal and allowing sewer gases to enter. Proper venting ensures that wastewater flows smoothly down the drain by gravity and air pressure.

Regular maintenance and inspections are important for the longevity and functionality of the sisäviemäri system. Blockages can occur due to grease, hair, or other debris, leading to backups and potential water damage. Addressing issues promptly helps maintain hygiene and prevents more significant problems.
