Sewer intermediate check valves prevent sewage, rodents and odors from backing up inside sewer systems. They are most commonly installed in the inspection manhole for access to the flapper actuator.
Sewer end dampers effectively protect installations from rats entering the building. They are made of plastic with the addition of a stabiliser to increase resistance to sunlight and other weathering.
