What is the minimum drain size for a laundry tub?

• A. 1 inch
• B. 1.5 inches
• C. 2 inches
• D. 3 inches

Answer: (B)

The minimum drain size for a laundry tub is 1.5 inches. This size is specified in plumbing codes to ensure that wastewater can flow freely and efficiently without causing backups or blockages. A 1.5-inch drain provides adequate capacity to handle the volume of water and debris typically generated from laundry tasks, such as washing clothes. Using a drain that is too small can lead to inadequate drainage, resulting in slow drains and possible overflow issues, which can cause problems in both functionality and hygiene. This makes 1.5 inches the standard minimum size to ensure effective operation of a laundry tub without posing risks of drainage issues.
