Storm drain or sewer cannot be layed within how many feet of a wall?

• A. 1 foot
• B. 2 feet
• C. 3 feet
• D. 4 feet

Answer: (B)

A basic clearance rule for storm drains and sewers is to keep them at least two feet away from any wall. This spacing gives enough room to excavate, lay and backfill the pipe, and still access the line for maintenance or future cleanouts without the wall getting in the way. Having this buffer also protects both the pipe and the wall: it helps prevent accidental damage to the wall’s waterproofing or foundation from backfill pressure, and it accommodates any movement or settling of the piping without crowding the wall. If the pipe were closer than two feet, working space would be cramped, making installation and future repairs difficult and increasing the risk of compromising the wall or its finishes. So, two feet is the practical minimum that aligns with safe installation, good maintenance access, and protecting the structural-walling interface.
