When boring under a hardscape, the sleeve for a 1 inch pipe must be at least which size?

• A. 1 1/2 Inch
• B. 1 Inch
• C. 2 Inch
• D. 3/4 Inch

Answer: (A)

When boring under a hardscape, you need a sleeve that provides space around the pipe so it can be laid or pulled through without rubbing or snagging on the bore edges. For a 1 inch pipe, the minimum practical sleeve size is 1 1/2 inches. That extra clearance protects the pipe from abrasion and makes installation smoother, while still avoiding excessive trenching. A sleeve that's only as large as the pipe would be tight and prone to damage; a much larger sleeve isn’t usually necessary and adds unnecessary work.
