Double elbow DN40 / 32 / 17-23 with check valve, connection for washing machine and dryer P155Z

Universal connection for household appliances

This double elbow with a check valve is designed to connect two household appliances – washing machine, dishwasher, dryer, or even a condensing boiler – to a single drain. It eliminates the need for additional siphons during the installation of subsequent devices, simplifying the installation and saving space. The polypropylene construction ensures durability and resistance to chemicals present in wastewater.

Functionality and construction

The elbow combines the functions of drainage and protection against backflow. The check valve prevents wastewater from flowing back from the sewer, which is especially important in buildings without their own protection. This avoids unpleasant odors and potential flooding. Two elbows with diameters of 17-23 mm allow connection of most standard drain hoses. In addition, the set includes a red plug that allows you to cap the unused elbow, preparing it for future connection of another device.

Advantages for the installer and user

• Quick installation: Direct connection to HT DN40/DN32 pipe eliminates the need for additional elements and shortens installation time.
• Versatility: The ability to connect two devices to one drain saves space and costs.
• Safety: The check valve protects against backflow of water and unpleasant odors.
• Flexibility: The plug allows you to secure the unused elbow and prepare it for future connections.
• Durability: Made of polypropylene (PP) – a material resistant to corrosion and mechanical damage.
• Future-proof: Easy connection of another device without the need to rebuild the installation.
• Simple maintenance: The construction allows easy access to the check valve if cleaning or replacement is necessary.

The hose connection diameter is 17-23 mm, and the material is polypropylene (PP).
