Air-Loc® Line Acceptance Test Procedure:
1. Install Back Plug. Attach poly lift line to pipe plug and place plug in line to be tested. Inflate plug to proper inflation pressure from above ground using hand pump.

2. Insert Front Plug. Connect triple hose assembly to front plug and insert plug into line. Connect other end of triple hose to Air-Loc® Control Panel.

3. Conduct Test. Connect air compressor to control panel. Then inflate front plug to proper inflation pressure. Introduce air through control panel until test pressure is achieved. Monitor pressure for the time designated for the test. If the pressure holds for the designated time losing one psi or less, the line passes and is “Accepted."
Cherne Air-Loc® Line Acceptance Test Procedure
   
Leak Location Test Procedure:
A leak location test needs to be conducted if the line acceptance test fails. The leak location test procedure is as follows:

1. String pipe using Cherne's Air-Loc Line Stringer or other method, attaching winch cable which is then pulled back through line.

2. Attach two pipe plugs connected together with interconnect hose to winch cable and place in pipeline.
3. Connect 500' triple hose to front plug.

4. Conduct pressure test on first 22' segment of sewer line and record results.

5. Advance plugs forward 22' using the winch and conduct test, once again recording results. Repeat procedure until entire line has been tested.

 

 

STAY OUT OF THE DANGER ZONE DURING THE TEST!!
Always block plugs when conducting air tests.
