📐 What is a Reducing Manhole?
A reducing manhole is a type of inspection chamber used where there is a change in the diameter of sewer pipes — usually from a larger to a smaller size or vice versa. It allows for easy maintenance, cleaning, and inspection of underground drainage systems. This type of manhole ensures a smooth transition of flow and minimizes the risk of blockage.
