How to Locate a Leak
Manhole testing is performed by creating a vacuum in the manhole and monitoring a gauge for vacuum loss. If a loss does occur, there is a simple way to locate the leak. You simply pour soapy water on the inside walls of the manhole, draw another vacuum and then look for the bubbles and you have identified the location of your leak.
*Always block plugs when conducting air tests!
