A sanitary tee may be turned on its back or side at an angle of not more than how many degrees?

The correct answer is 45 degrees because sanitary tees are designed to connect horizontal and vertical pipes while allowing wastewater to flow efficiently and to help prevent blockages or clogs. When a sanitary tee is installed at an angle, it is critical to maintain proper flow characteristics to ensure that gravity drains waste effectively without creating areas where debris can settle.

Installing a sanitary tee at an angle greater than 45 degrees could disrupt the smooth flow of wastewater, leading to potential slowdowns and blockages in the drainage system. Angles beyond this degree may also increase the risk of material buildup, which can compromise the system's integrity over time. Therefore, adhering to the 45-degree limitation is crucial for maintaining optimal functionality in plumbing systems.
