What is the maximum seal of fixture traps in inches?

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

Answer: (C)

The correct response for the maximum seal of fixture traps is based on plumbing codes that dictate how much water should be retained in a trap to effectively prevent sewer gases from entering the living space while still allowing proper drainage. A seal of 4 inches is the standard measurement established in plumbing regulations, ensuring that the trap has enough water to maintain its seal even under varying conditions, such as changes in flow or pressure within the drainage system. A seal less than this could risk allowing sewer gases to escape, while a seal greater than 4 inches does not provide any significant additional benefit and could potentially lead to drainage issues. Therefore, the established maximum seal of fixture traps is correctly set at 4 inches in order to balance effective drainage with the prevention of harmful gases entering the home.
