RETARDER TEE

• Professionalizes sub-membrane suction penetrations
• Provides a clean look and airtight seal at penetration point
• Creates a 7" high area forming a raised pocket to collect radon gas
• If piping under the retarder is desired, use the Tee or use 3" flex and route your pipe directly through the 4" Tee
• For easy connection to the top side of the Tee, use a schedule 4" PVC coupling or a rubber coupling to reduce down to your pipe size (See page 8 for Couplings)
