Connection set for wall-hung WC GEBERIT 152.426.46.1 PE d90/110 180 mm with cover caps

Connection set for wall-hung WC GEBERIT 152.426.46.1 PE d90/110 180 mm with cover caps is a factory-made plumbing accessory intended for connecting a wall-hung toilet to the building soil/waste system in concealed installations. Made of PE (polyethylene), the set accommodates both d90 and d110 pipe diameters and provides a 180 mm centre-to-centre spacing to match standard in-wall carrier frames. Cover caps are included to provide a neat visible finish and to protect connection points during installation and commissioning.

Advantages

The PE construction offers chemical resistance and durability while remaining lightweight and easy to handle. Compatibility with two common pipe diameters (d90 and d110) and the 180 mm spacing reduces the need for additional adapters or on-site modifications. Integrated cover caps improve the aesthetic outcome and protect connection surfaces from dirt and damage until the final toilet fitting. The prefabricated nature of the set simplifies installation time and helps ensure consistent alignment with the wall-hung WC outlet.

Suitable for

• Connection of wall-hung toilets to concealed soil/waste systems in new buildings
• Renovation projects where existing in-wall carrier frames use 180 mm spacing
• Installations requiring compatibility with d90 or d110 soil pipes
• Situations where a tidy finished appearance and temporary protection of outlets is needed

Key specifications

• Material: polyethylene (PE)
• Compatible pipe diameters: d90 and d110
• Centre-to-centre spacing: 180 mm
• Includes protective cover caps for visible outlet area
• Designed for concealed/wall-hung WC connections

How to use

Position the connection set so that the 180 mm spacing aligns with the wall-hung WC outlet and the in-wall carrier frame. Connect the set to the building soil pipe using the appropriate d90 or d110 end, ensuring a secure fit and correct orientation. Fit the wall-hung WC onto the carrier frame and make the final mechanical and seal connections according to the toilet and frame manufacturer instructions. Leave the included cover caps in place during construction to protect the outlet and remove them only when final fixtures are installed.

Usage recommendations

Verify compatibility of the set with the chosen wall-hung WC and in-wall carrier frame before installation. Use appropriate seals and follow local plumbing codes. During renovation, check existing soil pipe diameter and clear any debris prior to connection. For a durable installation, avoid excessive mechanical stress on the polyethylene connections and perform a leak test after completion.
