Keeping the top valve closed removes the latter reason from the equation and you might as well just have a valve with a plug in it. If the 2x1 or the lower valve breaks, closing the top valve stops the water flow while working on draining the system and returning it to normal dry service and installing the new parts on the drum drip - if the top valve or next fitting breaks, no such safety mechanism exists. This is of much greater consequence when dealing with a drum drip installed with a shoulder nipple into a system tee rather than at the bottom of a long drop pipe.

The purpose of the low point drain, of course, is to be able to drain water. Some is condensate, and some may be residual after a dump. Once all drains have been cleared, any water that accumulates will be condensate. > > The purpose of the drum is to allow draining without tripping the DPV. It is not specifically to contain water.
