## Long description

The TECE WC connection reduction is a high-quality polypropylene adapter engineered to facilitate the transition between DN 90 and DN 100 soil and waste pipe systems.

Its polypropylene construction is highly resistant to chemical degradation and mechanical stress, making it an ideal choice for waste water systems. The design simplifies the installation process, allowing for efficient retrofitting or new construction without the need for complex modifications to existing pipework.
Suitable for
Connecting DN 90 toilet outlets to DN 100 waste pipes

Retrofitting older plumbing systems
When it may not be suitable
This product is specifically designed for DN 90 to DN 100 transitions and will not be compatible with pipe systems of different nominal diameters. It is intended for use in standard gravity-fed waste water systems and should not be used in high-pressure piping applications.
Key specifications

How to use
To install the adapter, ensure that both the DN 90 pipe and the DN 100 pipe ends are clean, dry, and free of debris. Insert the adapter into the larger pipe while sliding the smaller pipe into the corresponding side of the reduction. Use appropriate plumbing lubricant if necessary to facilitate a smooth fit. Ensure the connection is fully seated to maintain a secure seal and prevent leaks.
What to consider before purchase
Verify the nominal diameter of your existing waste pipe
Check for sufficient space in the installation area
Ensure compatibility with your specific toilet outlet type
Usage recommendations: Always inspect the seals and pipe ends for damage before installation. It is recommended to test the connection for leaks by flushing the toilet several times after the installation is complete to ensure the integrity of the joint.
