Why is it not necessary to provide a high-point vent for pipes with a nominal diameter of less than 40 mm?

RT, why? Is it because it’s difficult to connect the branch valve?
It has nothing to do with the valve, right? 1/2\" valves are also very common. Given such a small volume and some gas inside, it’s easy for that gas to be carried out as the internal medium moves, right?
Really? I’m not sure of the specific reason
Analyzing each specific issue on its own – that sounds a bit absolute, doesn’t it?
Where did I see this? It just means it’s not necessary to set it, but it’s better if you do: lol
It’s SEI’s piping specification; it’s available online
Weren’t you the one who wanted to get to the bottom of things? ;P
Come on, there’s no need for something so simple; besides, I can’t do simulations either, so making it that complicated would just add more trouble
