What Mike said, I know of a property in Memphis where it wasn't unusual to get 5 gallons of water out of the drum drips, they had several hundred on all their systems. Used to take one man a week just draining drum drips every September. Richard L. Mote ET Designeer Rowe Sprinkler Systems, Inc.

Too many Rookies on here!!!!! It's also called a condensate nipple and you use both valves when draining off the water by removing the plug, leave the bottom valve shut, open the top valve let the water drain into it, shut the top valve and then drain off the water. Keep doing this until there is no longer any water in the condensate nipple (drum drip) Mike > Subject: RE: Drum Drip- why 2 valves? > Date: Tue, 13 Jul 2010 10:43:51 -0500 > From: [email protected] > To: [email protected]; [email protected] > > Brad, > > If the container is plugged and the top valve open, it is exposed to > system pressure which could be anything from 10 to 50 psi.
