What's the best way/ device for pressure testing lines on an inground
I am currently using an expandable plug with a schrader valve for the plug. On the "business end" I am using a collaboration of a brass schrader valve for adding air through a PVC 90 with a gauge hooked to that with a coupler for connecting.
Problem is I have to cut PVC attach my device glue, dry, test, cut. Repeat...
Thanks for all advice.
