Ive witness it several times before. A RP was welded without the weep hole. Pad bulges. And we never plug (fitting) the weep holes.

Aside from venting gas during welding and providing you with a telltale  hole (notice of leaks as Chris said)udring operation, the weep hole is also use to perform a soap and bubble test (part of testing/exam prior to signoff). Received on Tue Sep 13 01:53:00 2005
