A manhole bottom backflow preventer is a device that effectively blocks the backflow of sewage. Advantages of a backflow preventer: effective protection of buildings low cost and easy installation possibility of removing the check damper on the ground surface without entering the manhole no need to call a specialist for maintenance resistance to corrosion, negative temperatures and chemicals the valve has successfully passed a series of tests required by PN-EN 13564 and has been awarded the CE marking The manhole is installed on the sewer pipe, usually to allow the possibility of inserting a mole in the sewer pipe to clean the branch when it becomes clogged. If the sewer pipe is longer, we recommend inserting a manhole every 20-25m. A manhole with a check valve will prevent the sewer backing up into the building or rodents crossing into dwellings. The maximum permissible depth of a manhole with a built-in check valve is 5m and the maximum operating temperature is 95°C. The inspection shaft with non-return flap is easy to install and can be mastered even by a novice hobbyist.
