@bigmark75f What is a standpipe? (I'm thinking I know this but I'm brain pharting; isomnia)
Is that how they "hung" upside down.
It makes some sense being emptied of water. It's the hanging that has me baffled. I've not seen a bucket handle I could use to hang a bucket upside down due to pivot height above center of gravity and lips rolled to the outer.diameter vs i.d where a hook could catch if hung sideways.
Hey, water would penetrate the sand clear to the bottom if it rained heavy too.
Then again firehouse maintenance is no joke and buckets not as numerous anymore..? 😁
I installed a lot of those yellow exhaust tubes for removing vehicle fumes from stations during start up and motor temp. retention. I was in more firehouses for more hours a week than many of the individual firemen would be, except a few super devoted brass here and there.
