When a lead flashing for a vent stack is used the minimum weight per square foot of the lead is ______________ pounds?

• A. 2
• B. 2.5
• C. 4

Answer: (B)

The minimum weight per square foot of lead used for flashing around a vent stack is 2.5 pounds. This specification is important to ensure that the lead flashing provides adequate protection against water intrusion and is durable enough to withstand environmental factors such as wind and rain. The weight of the flashing material contributes to its effectiveness in creating a watertight seal around the vent stack, helping to prevent leaks that could lead to water damage or other issues within the structure. The use of 2.5 pounds per square foot is a standard set in plumbing code practices, reflecting a balance between sufficient weight for effectiveness and practicality in installation.
