## Summary description

PVC WC connection adapter by VIEGA, model 103668, with nominal dimensions 110 x 150 mm. Designed to connect toilet outlet to soil pipe systems, it provides a rigid PVC transition between fixtures and drainage. Suitable for residential and commercial sanitary installations where a durable PVC coupling of these dimensions is required.

## Long description

The VIEGA WC connection adapter PVC 110 x 150 mm model 103668 is a rigid PVC transition designed to connect a toilet outlet to a soil or drainage pipe with a different diameter. Manufactured by VIEGA, this adapter provides a stable, dimension-matching connection between a 110 mm outlet and a 150 mm drain, intended for use in sanitary installations where a change in pipe size is required. The component is intended for fixed installation within concealed or accessible drainage runs and is compatible with standard PVC soil pipes and fittings of the corresponding diameters.
Advantages
This PVC adapter delivers a durable, corrosion-resistant connection that resists common chemical and moisture exposure in sanitary systems. Its rigid construction maintains alignment between the toilet outlet and downstream pipework, reducing the risk of deformation under load. The adapter simplifies installation where a direct match between fixture outlet and soil pipe is not available, avoiding on-site fabrication or multiple couplings.
Suitable for
Connecting a toilet outlet (110 mm) to a 150 mm PVC soil or drainage pipe
Residential bathroom and toilet installations
Commercial sanitary installations such as public restrooms and office buildings
Replacement or retrofit projects requiring a secure diameter transition
Key specifications
Material: Rigid PVC suitable for sanitary drainage applications
Connection sizes: inlet 110 mm, outlet 150 mm
Function: fixed transition between different pipe diameters in drainage systems
Compatibility: designed to mate with standard PVC soil pipes and fittings of corresponding diameters
Typical installation location: concealed or accessible drainage runs behind fixtures
How to use
Ensure both the toilet outlet and the receiving soil pipe are clean and free of debris before fitting. Dry-fit the adapter to confirm alignment and length required. Apply appropriate PVC solvent cement or follow the manufacturer’s recommended joining method for the specific pipe system in use; observe recommended drying and curing times. Position the toilet fixture and secure according to the fixture manufacturer’s instructions, verifying that the adapter maintains a straight, unstressed connection between outlet and soil pipe.
Usage recommendations
Verify compatibility with the existing drainage system materials and local plumbing codes prior to installation. For installations involving different materials (for example, transition to cast-iron or ABS), use appropriate transition fittings or adapters and sealing methods. Avoid excessive mechanical stress or bending at the connection point; support adjacent pipe runs and fixtures to prevent movement that could compromise the seal.
