What is the size of the trap for a dental cuspidor?

The correct size for a trap used in a dental cuspidor is indeed 2 inches. This size is specifically selected to accommodate the typical waste flow from a cuspidor, which may include larger volumes of liquid waste due to its function in dental practices.

A 2-inch trap is designed to prevent clogs while also providing adequate ventilation and drainage for the specific waste produced in dental procedures. Using a trap that is too small could lead to blockages, while a trap that is too large would not be necessary for the relatively modest volume of waste typically generated from a cuspidor.

In dental settings, hygiene and efficient waste management are crucial, which makes the proper size of the trap essential for maintaining overall plumbing integrity and preventing backflow or drainage issues.

While the other options may be common in various plumbing applications, they do not align with the specific requirements for a dental cuspidor, which necessitates the 2-inch trap for optimal performance.
