Just being cranky tonight. That's not exactly what the Certificate says. The section reads "Do you certify that you have a control feature to ensure that all cutouts (discs) are retrieved?"
Yep, I certify I have a control feature. Doesn't say anything to the effect I actually followed the feature or even removed the cutouts. And of course beer cans aren't addressed from leaving open ended pipes at night. It should read "I certify I have inspected and retrieved all the cutouts and any other materials that may cause an internal obstruction in the piping, sprinkler orifice or other system component." Of course we're still at the mercy of the fitter because there ain't a piece of paper in the world that makes a sprinkler system more reliable. I agree with all the should's. Hanging the cutout is a fantastic idea, ain't required though which was the original question.

Attaching the coupon to the tee is a pretty good SOP for the field work.
