## Overview

The KARMAT Horizontal PVC Sewage Drain Check Valve is a 110mm non-return valve designed to prevent backflow flooding and rodent intrusion in lower-floor sewage systems.

## Description

KARMAT Backwater Valves (non-return valves) effectively secure any rooms located on the lower floors against flooding caused by back flow of storm water and sewage. Back flow may be caused by intense rains, thaw or floods. Use of anti-flooding devices for rooms located on the lower floors is required by obligatory regulations related to technical conditions that are to be satisfied by building codes. The shape of the protecting guard and gasket has been designed to protect against damage of the gasket by rodents and sliding during sewage flow. Advantages: - Karmat backwater valves operate automatically and do not require any external power supply. Any operations related to the device’s use are very simple and possible to be carried out by any user; - Due care of workmanship and high quality materials used in the manufacturing process guarantee efficient operation and high durability of the product; - The device’s interior with its smooth surface properly profiled, protects against sediment collection and grants complete and undisturbed sewage flow. - Gaskets have been manufactured from a rubber of high resistance to atmospheric influences and to aging Owing to its construction the Karmat backwater valve may successfully replace an access pipe installed in the outlet of sanitary sewage pipes from buildings. Backwater valves are installed in horizontal sewage pipes before they exit a building or sewage drain outside the building before its connection to an external network. They are also installed in inspection chambers made of concrete or plastic. Backwater valves are made of high-quality polypropylene (PP), a very durable and environment-friendly material. Polypropylene is resistant to the effects of aggressive chemicals and hot sewage (up to 95°C). Movable construction elements of valves are made of a material strengthened with fiberglass.
