Introduction
This manual provides essential information for the proper installation, operation, and maintenance of the Sioux Chief TurboVent 250 Series Schedule 40 1-1/2 in. Hub x 2 in. Dia. Hub PVC Air Admittance Valve. Please read this manual thoroughly before installation and retain it for future reference. This valve is designed to allow air into the plumbing drainage system when negative pressure occurs, preventing siphonage of fixture traps, and to close tightly when positive pressure is present, preventing the escape of sewer gases.
Product Overview

Safety Information
- Always consult and comply with local plumbing codes and regulations before installation.
- Wear appropriate personal protective equipment (PPE), such as safety glasses and gloves, during installation.
- Ensure the work area is well-ventilated.
- Do not use this air admittance valve in pressurized systems. It is designed for drainage, waste, and vent (DWV) systems only.
- Keep out of reach of children.
Setup and Installation
- Location: Install the air admittance valve in an accessible location, typically within the branch drain or stack, above the flood level rim of the highest fixture it serves. Ensure it is installed vertically.
- Preparation: Ensure all PVC pipes and fittings are clean and free of burrs. Dry fit the valve to confirm proper alignment.
- Solvent Welding: Apply appropriate PVC primer and solvent cement to both the valve's hub connections and the mating PVC pipe ends. Follow the solvent cement manufacturer's instructions for application and curing times.
- Connection: Firmly insert the pipe into the valve's hub, twisting slightly to ensure even distribution of cement. Hold in place for a few seconds to allow the bond to set.
- Curing: Allow sufficient curing time before testing the system, as recommended by the solvent cement manufacturer.
- Ventilation: Ensure the valve's screened opening is not obstructed, allowing for proper air intake.
Note: This valve is designed for Schedule 40 PVC systems. Verify pipe compatibility before installation.
Operation
The Sioux Chief TurboVent 250 Series Air Admittance Valve operates automatically based on pressure differentials within the plumbing drainage system. When water drains, it creates negative pressure (a vacuum) in the pipe. The valve's internal mechanism opens, allowing fresh air from the room to enter the drainage system, preventing trap siphonage and ensuring smooth flow.
When the flow stops, or positive pressure is present (e.g., from sewer gases), the valve's internal seal closes tightly, preventing the escape of foul odors and gases into the living space. No manual intervention is required for its operation.
Maintenance
The TurboVent 250 Series Air Admittance Valve is designed to be largely maintenance-free. However, periodic inspection is recommended:
- Visual Inspection: Periodically check the valve for any visible damage, cracks, or obstructions around the screened vent opening.
- Cleanliness: Ensure the vent opening is clear of dust, debris, or lint that could impede airflow. Gently clean with a soft brush if necessary.
- Functionality Check: If you suspect a venting issue (e.g., gurgling drains, slow drainage), inspect the valve. A properly functioning AAV should allow air in when a fixture drains and seal when not in use.
Do not attempt to disassemble the valve, as it is a sealed unit and not designed for internal servicing.
Troubleshooting
If you experience issues with your plumbing system that you suspect are related to the air admittance valve, consider the following:
- Slow Drainage or Gurgling Sounds:
- Check for Obstructions: Ensure the valve's vent opening is not blocked by debris.
- Valve Failure: An AAV that fails to open will cause negative pressure issues. Temporarily remove the valve (if possible and safe to do so, ensuring no sewer gas escape) to see if drainage improves. If it does, the valve may need replacement.
- Improper Installation: Verify the valve is installed vertically and at the correct height according to local codes.
- Sewer Gas Odors:
- Valve Failure: An AAV that fails to close can allow sewer gases to escape. This indicates the valve needs replacement.
- Loose Connections: Check for any leaks or loose connections at the valve's hub.
If troubleshooting steps do not resolve the issue, it is recommended to consult a qualified plumbing professional.
