Manhole Vacuum Testing

Vacuum testing is a quick, safe and practical way to validate manhole system integrity. Manhole sections can be tested at the precast concrete plant prior to delivery or on site prior to backfilling.

All Pipeline TV & Air Testing, Inc. performs manhole testing by creating a vacuum in the manhole and monitoring a gauge for vacuum loss.  The goal is an airtight environment and the test insures there are no leaks with a negative pressure test.
