I vote for the top valve being open providing the plug is in place and tight in the bottom one. I thought the reason for the bell couplings and larger nipple was more volume for condensate. I've stashed the handles in the spare head cabinet before just to be safe. One more thing, take out the plug and put in a fused head and bushing and it's a good inspectors test too.
Tom GRS Hello Ed, In this area we usually keep both valves closed... Kids and Tourist like to mess with with ANYTHING they can get their hands on... And of course the maintenance person "forgot to put it back" or "lost" the plug when they drained it "a couple of days ago" (or that had already been stolen). In the last 2 years we have sent people to rental car companies at the airport 5 times to retrieve fire extinguishers that have been left in rental cars when they were returned.... We sell 15-20 fire hose nozzles each year that come up "missing". Sunday, May 13, 2007, 1:10:39 PM, you wrote: > We are being sort of nit picky here, but it is interesting.
