Found it! Wound up putting a smoke cartridge in a vent, then putting
a continuous 20 PSI on it (enough to blow out the hole but not enough
to blow water out of the traps). Found it next to a tub access hole--
someone had widened the access hole and got a little wild with the
sawsall!.

Correction, I had the regulator on the compressor set at 20. Never
got that high in the pipe I suppose because of the leak..
