Sioux Chief 250-11A TurboVent Air Admittance Valve with 1-1/2" ABS Adapter

The Sioux Chief 250-11A TurboVent is an air admittance valve (AAV) designed for DWV rough-in installations where a conventional vent stack is impractical. This boxed unit ships with an included DWV connection adapter sized for 1-1/2" ABS pipe, letting a plumber tie the valve directly into the drain-waste-vent system without running additional vent piping to the roof. The valve's internal actuating device spins with every activation cycle, which helps keep the sealing surface free of dust and debris over repeated use. During drainage the valve opens to admit air and then seals tight, holding against up to 13 PSIG of back-pressure to maintain trap seals throughout the fixture branch.

Key Features

  • DWV Connection Adapter Included: Comes with an ABS adapter sized for 1-1/2" connections, simplifying tie-in to existing DWV piping.
  • Self-Cleaning Action: The internal actuating device spins with each activation, keeping the seal free of dust and debris for reliable long-term operation.
  • Back-Pressure Rated Seal: Valve opens during drainage and seals tight against up to 13 PSIG of back-pressure, helping protect trap seals.
  • Protective Debris Cover: Each unit ships with a protective cover to keep the valve clean prior to and during installation.
  • No Pipe Dope Required: Installation instructions specify that pipe dope should not be used on this valve's connections.
  • Boxed, Individually Packaged: Supplied as an individually boxed unit, with 6 EA per master pack.

Sioux Chief 250-11A – Frequently Asked Questions

1) Will the Sioux Chief 250-11A TurboVent connect to 1-1/2 inch ABS DWV pipe?
Yes. The 250-11A ships with an ABS DWV adapter sized for 1-1/2 inch connections, so the valve ties straight into a 1-1/2 inch ABS branch with no extra bushing. The adapter is ABS, so it solvent-welds to ABS piping. If your rough-in is PVC or a different pipe size, this is not the right version to order.
2) Can I use an air admittance valve instead of running a new vent to the roof?
That is exactly what the 250-11A TurboVent is for. It admits air into the drain line during drainage to protect trap seals, so a fixture branch can be vented without extending vent piping through the roof. Typical uses are remodels adding a fixture where no vent run exists, island sinks and other spots where a conventional stack is impractical, and new ABS DWV work. A roof vent stack is still required somewhere on the system; an AAV vents the branch, it does not replace the building's main vent.
3) How much back-pressure will the 250-11A TurboVent hold before it leaks?
The valve seals tight against up to 13 PSIG of back-pressure. That matters on a branch that can see positive pressure surges from upstream discharge: the valve opens one way to admit air, then closes and holds, so the surge does not push sewer gas out through the vent or break the trap seals downstream.
4) Should I use pipe dope or sealant on the TurboVent connection?
No. The installation instructions for the 250-11A specifically say not to use pipe dope on the valve's connections. Make the joint dry at the valve and use the included ABS adapter for the solvent-weld tie-in to the pipe.
5) Do air admittance valves clog up with dust over time?
The TurboVent's internal actuating device spins on every activation cycle, which wipes the sealing surface clear of dust and debris as it works. Each unit also ships with a protective cover so construction dust does not reach the valve before and during rough-in. Leave that cover on until the opening is closed up.
6) How is the Sioux Chief 250-11A packaged for a multi-unit job?
Each 250-11A comes individually boxed with its adapter and debris cover, and master packs hold 6 each per case. Useful if you are stocking a truck or roughing in a run of fixtures and want them to arrive protected rather than loose.
7) Is the Sioux Chief TurboVent AAV made in the USA?
Yes, the 250-11A TurboVent is manufactured in the United States, which matters on public and institutional work with domestic sourcing requirements.
8) What part number do I order for the 1-1/2 inch ABS TurboVent?
Order Sioux Chief 250-11A. That is the TurboVent air admittance valve supplied with the 1-1/2 inch ABS DWV adapter, debris cover, and instructions in one box.
