TL;DR
A Studor vent is a brand of air admittance valve, a one-way device that opens under drain-flow suction to let air into the plumbing system and reseals by gravity to keep sewer gas out. It substitutes for a vent pipe through the roof where running one is impractical, as with island sinks, basement baths, and some remodels.
What it means
A Studor vent is a brand of air admittance valve, a one-way device that opens under drain-flow suction to let air into the plumbing system and reseals by gravity to keep sewer gas out. It substitutes for a vent pipe through the roof where running one is impractical, as with island sinks, basement baths, and some remodels. Plumbing codes accept them with conditions, requiring accessible installation above the trap arm, and a worn one announces itself with gurgling drains or a sewer smell under the cabinet.
