## Overview

The KARMAT 160mm Horizontal PVC Backwater Valve is a high-quality, chemical-resistant check valve designed to prevent sewage and stormwater backflow in lower-floor rooms.

## Description

Karmat Backwater Valves (Check Valves) effectively ensure chambers located on the lower floors against flooding caused by backflow of stormwater and sewage. Return flow can be caused by heavy rain, thaw or flooding. The use of anti-flood devices for rooms located on the lower floors is required by mandatory regulations related to technical conditions that must be met by building codes. The shape of the seal guard and guard has been designed to protect against damage to the trim by rodents and by slipping during sewage flow. Advantages: - Karmat check valves work automatically and do not require external power supply. All operations related to the use of the device are very simple and possible to be carried out by any user; - Due to the manufacturing care and high-quality materials used in the manufacturing process guarantee the efficient operation and high durability of the product; - The interior of the device with its well-profiled smooth surface, protects against the collection of sediment and subsidies complete and intact sewage flow. - Seals were made from rubber of high resistance to atmospheric influences and aging Due to its construction, the Karmat check valve can successfully replace an access pipe installed in the outlet of sanitary sewage pipes of buildings. Check valves are installed in horizontal sewer pipes before they exit a building or sewer drain outside the building before its connection to an external network.
