Question 44

The minimum size trap for a laundry tray is 2 inches.

A laundry tray requires a minimum trap size of 2 inches to ensure proper drainage and prevent clogs.

A) 1 1/4 inches

This option is incorrect as a 1 1/4 inch trap is not sufficient for the drainage needs of a laundry tray. Such a small size may lead to inadequate flow and potential blockages.

B) 1 1/2 inches

While a 1 1/2 inch trap is larger than 1 1/4 inches, it still does not meet the minimum size requirement for a laundry tray. This size may not effectively handle the volume of water typically discharged from a laundry tray.

C) 2 Inches

This is the correct answer, as a 2 inch trap is the minimum size required for a laundry tray. It provides adequate drainage capacity, reducing the risk of overflow and ensuring proper functionality.

D) 2 1/2 inches

Although a 2 1/2 inch trap exceeds the minimum requirement, it is not the minimum size needed. This option may be appropriate for larger installations but is not necessary for a standard laundry tray.

Conclusion

The 2 inch trap size is essential for effective drainage of a laundry tray, ensuring it can handle the necessary water flow without issues. Options A and B are too small, and while D is larger than required, it does not represent the minimum standard. Therefore, C is the definitive correct answer.
