摘要：
Methods and apparatus for checking emitter bonds in an irrigation drip line and for manufacturing drip line in a manner that allows the bond between the in-line emitter and surrounding conduit to be checked. In one form, a downstream in-line vacuum tester is provided for monitoring the amount of air escaping from outlet openings in the drip line to detect excessive air associated with poorly bonded emitters.
