We have discussed standpipes in the past, but I think it is worth mentioning again. Standpipes in large and high rise buildings are our water source. It is important to know the location of these devices and to ensure that they are not obstructed.
In addition we need to know and understand if they have pressure reducing devices and how that affects our operations. Study up on these systems and know how to adapt and trouble shoot the stand pipes in your area.
The picture shown is a stand pipe in a hotel. I went to ice in the hotel I was staying in and this was right next to the ice machine. I didn't measure it, but this standpipe would be very difficult to connect to. Additionally, if we did get connected with hose only, there would certainly be a kink at the coupling, further reducing our pressure.
This might be a time when we would try to put an elbow on the connection prior to connecting our hose. However, I think that with this particular standpipe connection, it would be a stretch just to get the elbow connected as well.
Know your buildings and their systems. Prepare for these types of problems and come up with solutions before you have a fire. Thanks for reading and train hard.
