Using the water method, what is the maximum permitted water loss for a 200‑ft section of 24‑inch pipe per day?

• A. 6.0 gallons
• B. 9.2 gallons
• C. 12.0 gallons
• D. 15.0 gallons

Answer: (B)

When using the water method, you’re testing how much water can be lost along a section of pipe while it’s full of water. There’s an established leakage allowance that depends on the pipe diameter and length. For a 24-inch pipe, the standard permit is about 4.6 gallons per day for every 100 feet of pipe. A 200-foot section is two times 100 feet, so you multiply: 2 × 4.6 = 9.2 gallons per day. Therefore, the maximum permitted water loss for a 200-foot section of 24-inch pipe is 9.2 gallons per day. The other values would exceed this standard allowance.
