Why does the pipe need to do that before (or after?) the valve? Seems like a weird flex.
I'm assuming that it is similar to the trap in your sink. Except because hydrogen is the lightest element, it has to be upside down. Confident that this is for preventing backflow when the valve is closed and the pipe is opened for maintenance.
Edit: I appear to be incorrect and it has to do with handling the expansion and contraction of the pipe.
Yes it is called a lyre-shaped bow. It compensates for expansion/ contraction happening when the pipe heats or cools.
Hey, thanks for the official term.
Thank you, and Novi too!
Pipes are notoriously gay. Can't make them do it.
