In testing successive sections, test at leas t upper 10 feet

(3 m) of next preceding section so that each joint or pipe except upper most 10 feet (3 m) of system has been submitt ed to a test of at least a 10 feet (3 m) head of water. Water shall be kept in the system, or in portion under test, for at least 15 m inutes before inspection starts. System shall then be tight at al l joints.
