The T&P waste line pipe shall be within ____ inches from the finished floor

The T&P waste line pipe shall be within ____ inches from the finished floor

• A. 2 Inches
• B. 4 Inches
• C. 6 Inches
• D. 8 Inches

Answer: (A)

Temperature and pressure relief valves are safety devices on water heaters. When the valve opens, it releases hot water and steam through a dedicated discharge line. That line must lead to a safe drainage point so any discharge is visible, controllable, and cannot damage surrounding components or create a scald hazard. Placing the discharge pipe close to the finished floor keeps the effluent at a low height where it can drain quickly into a floor drain or other approved drain, and it prevents discharge from running along walls or into cabinets. This proximity also makes it easier to observe the discharge and ensures a clear, unobstructed path for drainage. The standard practice in many codes is to terminate the discharge within about six inches of the finished floor, ensuring a reliable drainage route. Some study materials may list different numbers, but the key idea is to keep the T&P discharge as close to the floor as practical to promote safe, effective drainage. Always follow the local code requirements for the exact distance.
