______________________ is the minimum trap size for a bidet?

The minimum trap size for a bidet is 1-1/2 inches. This size is specified in plumbing codes to ensure that adequate drainage and waste removal can occur without risking clogging or backup. Bidets typically have a lower flow rate and smaller waste load compared to other plumbing fixtures. Therefore, a 1-1/2 inch trap provides sufficient capacity for the bidet's drainage requirements. Additionally, this dimension aligns with the standard practices outlined in plumbing codes, which aim to maintain efficient waste disposal systems while adhering to safety and health standards.

When sizing traps for different fixtures, it’s important to consider the volume of water and waste that will pass through them, but for a bidet, the specified minimum of 1-1/2 inches is adequate for efficient operation.
