Antisyphonage pipe is fitted A. At the end of septic tanks B. On manholes C. With a W.’trap D. At the beginning of sewer line

Here is a brief explanation of each option:

• A. At the end of septic tanks: This is not the correct answer because antisyphonage pipes are typically installed at the beginning of the sewer line, not at the end of the septic tank.
• B. On manholes: This is not the correct answer because antisyphonage pipes are not typically installed on manholes. Manholes are used to access the sewer line, but they do not have a direct connection to the sewer line.
• C. With a W.’trap: This is not the correct answer because antisyphonage pipes are not typically installed with a W.’trap. A W.’trap is a device that is installed in a sink or toilet to prevent sewer gases from entering the home.
• D. At the beginning of sewer line: This is the correct answer because antisyphonage pipes are typically installed at the beginning of the sewer line.
