LEAK TESTING

Polyethylene pipe may be hydrostatically tested to determine system integrity for leaks. When testing is required, observe all safety measures. Leak test procedures are given in Performance Pipe PP 802 Technical Note, Leak Testing of Polyethylene Pipe. Typically, HDPE pipe is leak tested to 1.5 times its Pressure Rating (PR). Allowable leak test pressures are shown in the following table.
