Product Description

Backflow Prevention Device (BPD) for 110mm Vertical Pipes

This Backwater Non Return Valve (NRV) protect buildings against flooding from back flow of storm water and sewage travelling back up the sewerage, drain or toilet systems during intense rains, thaws, or floods.

Suitable for Sewage (Soil) Pipes as well as Water and Rainwater Pipes. The simple and effective design also inhibits unpleasant smells from the sewage or drainage system.

KARMAT backwater valves are equipped with a manual closure lever. Changing of the lever from OPEN position A to CLOSED position B causes a complete arrest of sewage backflow. The interior of the non return valve is smooth ensuring non-interrupted flow of sewage through the device.

The flap guard (as well as all assembly elements (screws, nuts, washers)) are made from corrosion resistant chromium nickel giving effective protection against rats and other rodents.

The backflow valves can be installed in vertical pipes within the building or outside the building.

How does the Backflow Valve Work?

The Backflow Prevention Device has a Single Flap that allows sewage to flow through it from one direction, but the flap closes tightly shut when sewage or water pushes at it from the other direction. This simple mechanism ensures that, during flood events, basements and rooms located at lower levels are protected from sewage from the sewer system. It is a fully automatic operation that requires no external power supply and includes a lockable lever for emergency lockdown of the pipe network or for maintenance.
