Product Description

The OATEY SUREVENT is a one-way air admittance valve designed to allow air to enter a plumbing drain system when negative pressure develops in the piping. It supports up to 160 branch drain fixture units (DFU) and 24 stack DFU, making it suitable for a wide range of residential and light commercial drain-waste-vent applications. The valve ships with a PVC Schedule 40 adapter sized to fit 1.5-inch and 2-inch drain lines. Licensed plumbers install this valve as an alternative to extending a vent pipe through the roof where conventional venting is impractical or code-permitted alternatives are acceptable.

This air admittance valve is used in residential and light commercial plumbing systems where negative pressure in the drain line must be relieved to prevent trap siphonage. Typical applications include island sinks, cabinet installations, remodels, and any location where running a conventional vent to open air is not feasible. The included Schedule 40 PVC adapter allows direct connection to standard 1.5-inch or 2-inch drain piping commonly found in kitchen, lavatory, and utility sink configurations.

Key Features

  • Rated for 160 branch DFU and 24 stack DFU capacity
  • Fits 1.5-inch and 2-inch drain lines via included PVC Schedule 40 adapter
  • One-way valve operation opens under negative pressure and seals under neutral or positive pressure
  • Functions as a code-recognized alternative to conventional through-roof venting where permitted
  • Compatible with standard PVC Schedule 40 drain-waste-vent piping systems

Compatibility

Designed as an OEM-style replacement and new-installation air admittance valve for residential and light commercial PVC drain-waste-vent systems using 1.5-inch or 2-inch Schedule 40 piping.

Installation Notes

Installation must be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC), which governs where air admittance valves are permitted in lieu of conventional venting. Shut off water supply and ensure the drain system is depressurized before beginning work. The valve must be installed in an accessible location, oriented vertically per manufacturer and code requirements. Do not install in locations subject to freezing or where the valve may be permanently sealed within a wall cavity without an access panel.
