Made from durable polypropylene and stainless steel with UV and chemical resistance, it fits standard 160mm sewage pipes and ensures reliable, maintenance-free protection against stormwater and sewage backflow. ## Description Flap valves of Karmat are innovative devices protecting rooms on the lower levels against flooding caused by backward flow of storm water and sewage. These devices are fully self-activating. Flap valves effectively protect plumbing systems from rats entering the buildings. Flap valves are installed at the end of sanitary sewage pipes entering collection wells, cesspits or drainage pipes leading storm water to ditches or rivers. Advantages: - high quality polypropylene and stainless steel ending; - sun light/high temperature resistance; - immunity to aggressive chemical compounds Review: Macht wofür es entwickelt wurde - Die Funktion ist auch am Ende einer Abwasserleitung, z.B. in einem 1 m Kontroll-Schacht, gegeben. Der Schutz gegen eindringendes Ungeziefer ist gegeben. Bei richtigen Einbau (Gefälle 1%) sollten auch keine Toilettenrückstände vor der Klappe liegen bleiben. Review: FUNCIONA - Deja salir las aguas grises y evita los retornos de la arqueta general, funciona. Han pasado ya unos años desde que la instalé y no se han vuelto a producir retornos de aguas residuales desde la arqueta general. Muy buena compra. ## Features - Flap valves of Karmat are innovative devices protecting rooms on the lower levels; - Installed at the end of 160mm sanitary sewage pipes leading storm water to ditches or rivers; - Prevents against rodents entering building interiors through the sewage and other sanitary systems; - Secure the lower floors against flooding caused by back flow of storm water and sewage; - High quality PVC Plastic and stainless steel ending, sun light/high temperature resistance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BWS5V8A | | Best Sellers Rank | 184,616 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 490 in Check Valves | | Brand | PLUMBING4HOME | | Customer Reviews | 4.4 out of 5 stars 10 Reviews | | Exterior Finish | Nickel | | Exterior finish | Nickel | | Inlet Connection Size | 160 Millimeters | | Inlet connection size | 160 Millimeters | | Item Type Name | 160mm non return valve | | Item Weight | 0.75 Kilograms | | Manufacturer | Karmat | | Material | Nickel, Polypropylene (PP) , Polyvinyl Ch | | Model Number | [POSSIBLE] PLUMBING4HOME-RV160 | | Number of Ports | 2 | | Number of ports | 2 | | Outlet Connection Size | 1.6E+2 Millimeters | | Outlet connection size | 1.6E+2 Millimeters | | Part Number | 452c | | Unit Count | 1.0 count | | Valve Type | Flap Valve | ## Product Details - **Brand:** PLUMBING4HOME - **Exterior finish:** Nickel - **Inlet connection size:** 160 Millimeters - **Manufacturer:** Karmat - **Material:** Nickel, Polypropylene (PP), Polyvinyl Ch - **Number of ports:** 2 - **Outlet connection size:** 1.6E+2 Millimeters ## Images ![PVC Plastic Check Flap Valve Self Activating End Drainage Backwater 160mm - Image 1](https://m.media-amazon.com/images/I/511ysPT6r0L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Macht wofür es entwickelt wurde *by M***. on 5 November 2024* Die Funktion ist auch am Ende einer Abwasserleitung, z.B. in einem 1 m Kontroll-Schacht, gegeben.
