Sand traps require a trap size of what inches?

Sand traps require a trap size of what inches?

• A. 4 inches
• B. 2 inches
• C. 3 inches
• D. 5 inches

Answer: (A)

Sand traps are built to intercept and hold sand and other heavy sediment before wastewater enters the drain, so the trap must be large enough to slow flow, capture solids, and allow easy cleaning. Four inches in diameter is the standard size because it provides sufficient capacity to settle out sediment and still be practical to service. Smaller sizes would clog more quickly and offer less sediment capacity, while a larger size isn’t typically required for ordinary installations. So, four inches is the typical trap size for sand traps.
