About Studor 20396 Trap-Vent Integrated Trap And Air

The compact Studor Trap-Vent is a combined trap with a 2" water seal and an integrated air admittance valve, reducing the need for secondary ventilating and replacing conventional P-traps. The valve within the Trap-Vent opens and admits fresh air when the negative (suction) pressure occurs from a fixture discharging into the system. This equalizes the pressure within the system and protects the trap seal. When the flow stops, the valve closes by gravity, preventing any transmission of sewer gas. The Trap-Vent is the ideal plumbing solution for remodels, restorations and floating sinks. Trap-Vent is for use on a lavatory, water cooler or sinks that do not receive a discharge from any appliance. Trap-Vent is rated up to 6 DFUs on a horizontal wet vent. The Trap-Vent cannot be installed on kitchen sinks, laundry tubs, or a sink that receives discharge from any kind of appliance. Do not use where pumps or pressurized flushing devices are used. Please follow all instructions carefully during installation. UV stabilized ABS construction with a temperature rating of 32 - 150 deg F.
