I have a similar issue and its a small leak at the interface between the DL T fitting and the shiny plastic round gasket on the fabric. Only noticeable when doing a negative test. Could only find it when doing a negative check with wet CL's and my ear clse to the T when sucking it negative.

Thanks John,
Sounds like a similar problem and I'll take a closer look at the joint between the fabric and plastic on the counter lung.
