This provides a settling place for dirt particles which may be present in the spray solution or equipment. This also prevents drainage when the boom shut-off is closed. Occa- sionally, such a boom should be flushed out through removable caps on the ends. Nozzles may be brought into the bottom of the boom with a nipple or coupling raised into the boom to provide settling space. However, the coupling obstructs the boom line, making it impossible to force rod cleaners through from the ends. The boom may be drilled, and a 90- degree elbow (1) or a coupling (2) welded over the hole. Or openings may be made in the boom for the nozzles by drill- ing and tapping the boom, screwing in a street elbow (3) or a nipple (4), and welding in place. Welding is necessary to preserve structural strength. Suitable el- [26].
