What is the designation of the trap used to separate the internal house drainage from the municipal sewer_________________?
Show answer Hide answer
Answer: D. All the above
Explanation
Master traps, intercepting traps, and interception manholes perform identical functions in plumbing networks. These specialized devices prevent foul sewer gases from entering internal building drainage systems. Plumbing codes recognize all these interchangeable terms for sewer isolation equipment installations. Drainage separation is a critical public health requirement for modern urban building construction. Intercepting traps maintain a water seal that blocks vermin and noxious gases from municipal mains. Access manholes allow maintenance workers to clear blockages and inspect the main drainage connection.
Municipal authorities mandate these isolation devices to protect community health and sewer infrastructure. Plumbers install intercepting traps at the boundary where private property drains meet public sewers. Proper trap maintenance prevents unpleasant odors and dangerous gas accumulations inside residential dwellings. Limiting the definition to only master traps ignores alternative accepted terminology used by engineers. Excluding interception manholes misses the broader structural chambers used for municipal drainage separation. Treating these terms as distinct device types contradicts standard sanitary engineering definitions.
