Sitech+ Pipes & Fittings

The WAVIN SiTech+ 3067775 is an 87.5° acoustic reducing drainage tee, designed for creating a 50 mm branch connection from a 75 mm drainage line. It is intended for internal soil and waste drainage installations where effective drainage and reduced operating noise are required. The fitting forms part of the WAVIN SiTech+ sound-reducing drainage system. Its 75 x 50 mm reducing configuration allows pipes of different diameters to be incorporated into the same drainage installation without requiring a separate reducer. The fitting uses socket/push-fit connections and incorporates SBR sealing rings, allowing straightforward and secure installation with compatible WAVIN SiTech+ components.

The WAVIN SiTech+ 3067778 is an 87.5° acoustic reducing drainage tee, designed to create a 50 mm branch from a 110 mm main drainage line. It is part of the WAVIN SiTech+ sound-reducing system for internal building drainage. Manufactured from mineral-reinforced polypropylene (PP-MD), the fitting combines durable construction with the acoustic properties of the SiTech+ system. Its reducing 110 x 50 mm configuration allows pipes of different diameters to be connected without requiring a separate reducer. The fitting incorporates SBR sealing material for secure installation with compatible SiTech+ components. Its 87.5° configuration is suitable for installations requiring an almost perpendicular branch from the main drainage line.

The WAVIN SiTech+ 262246 is an 87.5° acoustic reducing drainage tee designed to create a 75 mm branch from a 110 mm main drainage line. It is part of the WAVIN SiTech+ sound-reducing drainage system for internal soil and waste installations. Its 110 x 75 mm reducing configuration allows drainage pipes of different diameters to be connected directly, eliminating the need for an additional reducer. The 87.5° branch provides an almost perpendicular connection to the main drainage line. Designed for reliable installation within the SiTech+ system, the fitting combines secure push-fit assembly with the low-noise characteristics of WAVIN SiTech+ drainage components.

The WAVIN Sovent Airmix 3003791 is a 110 mm soil stack ventilation fitting designed for building drainage systems. Installed on the vertical soil stack, typically at each floor, it allows air to circulate within the drainage system and helps prevent negative pressure from developing even when wastewater flow rates are high. The fitting is manufactured from PE-80 polyethylene and features multiple connections for integrating branch drainage lines into the main 110 mm stack. Its design helps control the interaction between wastewater and air within the stack, supporting efficient drainage and reducing the need for a separate parallel ventilation stack in suitable Sovent system designs. With a total length of 732 mm and a continuous maximum medium temperature of 90°C, the Sovent Airmix is designed for professional building drainage applications.  

The WAVIN SiTech+ 3067837 is an acoustic double drainage tee with 45° branches, designed for connecting two branch drainage lines to a 110 mm main soil or waste pipe. The fitting incorporates two 50 mm branch connections, positioned to provide an efficient double connection within a single fitting. Part of the WAVIN SiTech+ low-noise drainage system, it is designed for internal building drainage where reduced wastewater noise and reliable performance are required. SiTech+ uses mineral-reinforced polypropylene, with heavier fittings helping to reduce the transmission of water-flow noise. The 45° branch configuration promotes a smoother entry of wastewater into the main drainage line and provides a practical solution where two 50 mm drainage branches need to connect to the same 110 mm line.

The WAVIN SiTech+ A110X3 is an acoustic drainage pipe designed for internal soil and waste drainage systems where reduced operating noise is required. With a diameter of 110 mm and a length of 3 m, it is suitable for residential, commercial and multi-storey building installations. The SiTech+ pipe features a multi-layer polypropylene construction with mineral-reinforced material, designed to increase mass and reduce the transmission of noise generated by wastewater flow. Its smooth inner surface supports efficient drainage flow, while its durable construction provides reliable performance under the demanding conditions of sanitary wastewater systems. Designed as part of the WAVIN SiTech+ low-noise drainage system, the pipe can be combined with compatible SiTech+ fittings and accessories to create a complete acoustic internal drainage installation.
