What is the permitted leakage per 24 hours when testing a 1 inch pipe 1,000 feet long?

• A. 100 gal
• B. 200 gal
• C. 300 gal
• D. 400 gal

Answer: (B)

During hydrostatic leakage testing of a pipe, there is a standard allowance for how much water can be lost in 24 hours, based on the pipe size and length. For a 1-inch diameter line, the accepted leakage is 200 gallons per 24 hours for every 1,000 feet of pipe. So, with a 1,000-foot length, the test may lose up to 200 gallons in a day and still be considered acceptable. This allowance accounts for minor seepage at joints and fittings under test pressure. If the observed leakage is more than 200 gallons in 24 hours, the test would not pass; less than or equal to 200 gallons passes. The other numbers correspond to different sizes or lengths and don’t match this scenario.
