Sewer/ventilation valve 50 mm

The 50 mm sewer/vent valve is installed on non-ventilated sewer risers to prevent the water seals of plumbing fixtures from being blown during peak flow hours. Under normal conditions, the water seals block odors. 

This trap trap is a small amount of water that remains in the bend of the trap, preventing sewer gases from entering the room. Sometimes, when several plumbing fixtures are in operation simultaneously, these seals are blown off—a sudden change in pressure forces water out, and sewer gases escape into the room.
