Air-Loc® Leak Location Kit. If the line acceptance test indicates a leak in the sewer line, it becomes necessary to locate the leak(s) so that proper repairs can be made.
A leak location (segment) test is accomplished by first stringing the sewer line using a Cherne Air-Loc Line Stringer or float line. Once strung, a winch cable is used to pull two Air-Loc Leak Locator plugs, which are attached together with an interconnect hose, through the pipeline in 22′ intervals. Air is introduced between the plugs at each 22′ increment until the test fails. Then, by moving the plugs back and forth, the leak can be isolated within two feet.
Air-Loc® leak locator plugs are designed for both low-pressure sewer line acceptance tests as well as leak location testing. Air-Loc® plugs can also be used to block flow by simply plugging the fill and readback ports.
“Front” Air-Loc® Leak Locator Plugs also come equipped with:
AIR LOC LEAK LOCATOR PLUG 200-300MM, AIR LOC LEAK LOCATOR PLUG 300-450MM, AIR LOC LEAK LOCATOR PLUG 150-300MM
