ABS or PVC safe pans or liners shall be how many or how many mil?

20 30
25 35
30 40
35 45

The correct answer is: 30 40

The correct answer indicates that ABS or PVC safe pans or liners shall have a thickness of 30 mils to 40 mils. This requirement ensures durability and effective containment in plumbing applications, preventing moisture and potential leaks from causing damage to surrounding structures. The specified thickness provides a strong barrier that is necessary for safe drainage installations. Thicker materials like the range offered in this answer ensure that the safe pans or liners can withstand both the weight of the plumbing fixtures and the potential impact from cleaning or maintenance activities. The other ranges in the options do not meet the minimum requirements outlined in the Illinois Plumbing Code for safe pans or liners. Therefore, they would not provide the reliable protection that is critical in plumbing systems.
