VIEGA Viega 3815 pipe section, inner diameter 100 mm, length 4000 mm

VIEGA Viega 3815 pipe section with a 100 mm inner diameter and 4000 mm length is a straight plastic pipe designed for use in plumbing and drainage systems. The pipe provides a long-run, smooth bore for wastewater, venting and conduit applications and is compatible with matching Viega fittings incorporating lip-seal connections. Its straight profile and consistent internal diameter support reliable flow and integration into residential and commercial installations.

Advantages

The pipe's plastic construction offers corrosion resistance and low weight compared with metal alternatives, simplifying handling and installation. The consistent 100 mm bore and long 4000 mm length reduce the number of joints required for extended runs, lowering potential leak points. Compatibility with lip-seal fittings ensures secure, water-tight connections without the need for bonding or welding.

Suitable for

• Wastewater drainage runs in residential and commercial buildings
• Venting and air admittance lines
• Conduit and service routing where a straight 100 mm bore is required
• Integration into sanitary stacks with compatible fittings

How to use

Measure and cut the pipe to the required run length if shorter pieces are needed, ensuring clean, square ends. Insert the pipe into compatible lip-seal fittings or couplers following the fitting manufacturer's insertion depth guidelines. Ensure alignment and full engagement of the lip seal to achieve a water-tight joint. Support the pipe at regular intervals along its length according to local plumbing codes and the fitting manufacturer's recommendations to prevent sagging and maintain proper slope for drainage.

Usage recommendations

Store and handle the pipe in a manner that avoids prolonged UV exposure and mechanical damage. When joining, verify that both the pipe and fittings are free of debris, and use appropriate supports, slopes and access points to facilitate inspection and maintenance in installed systems.
