ABSTRACT:
A cesspool for handling waste water passed through the cesspool to an associated drainage system has two separate odor locks for preventing the escape of odoress gas from the drainage system through the cesspool. A downwardly extending inlet member is surrounded by and protrudes downwardly into a vertically movable cup. Water held by the cup normally provides a first odor lock between the cup and the inlet member. The cup is biased upwardly and has an upper edge which is engagable with an elastic seal to provide a second odor lock. The second odor lock assures an odor seal between the inlet member and the cup even when the water in the cup falls below the level required to maintain the first odor lock.
