## Overview

The Karmat Drainage Flap Valve is a robust, self-activating non-return valve designed for universal 72-100mm sanitary sewage pipes.

Certified to ASTM and ISO standards, it ensures reliable protection for lower floors and plumbing systems.

## 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: buono - ok, ottima per tubi corrugati, ma io dovevo montarla su tubo liscio del diametro 100... il diametro in realtà è un 110 e non un 100.... Ho dovuto procurarmi una riduzione dal costo di pochi euro, ma senza di quella non avrei potuto montare la valvola. spero di non averne bisogno, ma nel caso spero funzioni!
